      Entanglement and relativistic effects for Gaussian states
      We present for the first time an analytic formula for the entanglement of formation (EoF) of general bipartite Gaussian states. We show through physical examples that EoF is a superior measure of entanglement than Negativity. We also discuss an unexpected decoherence effect when detecting the radiation from accelerated quantum sources.
    • 09:45 Patrick Maletinsky
      Single spin quantum sensing and imaging
      Electronic spins yield excellent quantum sensors, offering quantitative, nanoscale sensing down to single spin levels. I will present our recent achievements in employing electronic spins for nanoscale magnetometry of solid-state systems. I will focus on quantitative quantum sensing of antiferromagnets and superconductors and how it competes with state-of-the-art magnetic imaging.
    • 10:15 David Hunger
      Purcell-enhanced single-photon emission from colour centers in diamond coupled to tunable microcavities
      We use a fully tunable microcavity to demonstrate the control of spontaneous emission from nitrogen-vacancy and silicon-vacancy centers in diamond. This allows us to realize efficient and narrow-band single photon sources under ambient conditions.

    • 11:15 Stefano Pirandola
      Capacities of repeater-assisted quantum communications
      We bound the ultimate rates for distributing secret keys via quantum repeaters, from the basic scenario of a single repeater chain to an arbitrarily-complex quantum network, where systems may be routed through single or multiple paths. We establish the end-to-end capacities under fundamental noise models, including optical loss.
    • 11:45 Robert J. Sewell
      Simultaneous tracking of spin angle and amplitude beyond classical limits
      We simultaneously squeeze two non component of the angular momentum of an atomic ensemble. We show how to reduce the quantum mechanical back action below δF~N^1/2, the classical limit for N spins.
    • 12:05 Lambert Giner
      Hacking heisenberg’s uncertainty principle with quantum clones
      Performing simultaneous non-commuting measurements on a single quantum system is impossible because of the disturbances generated by the measurements. However, if one possesses two copies of the system, this problem can be overcome. We perform simultaneous non-commuting measurements and fully determine the state of the system using quantum clones.
    • 12:25 Anaelle Hertz
      A tight entropy-power uncertainty relations
      A proper expression of the uncertainty relation relies on entropy power. The resulting entropy-power uncertainty relation is equivalent to the entropic formulation of the uncertainty relation, but can be further extended to rotated variables. Hence, we prove a tighter form of the entropy-power uncertainty relation taking correlations into account.
    • 12:45 Lunch
    • 14:00 Konrad Banaszek
      Mode engineering for realistic quantum-enhanced interferometry
      We show that appropriate preparation and detection of the modal structure of photons used in quantum-enhanced interferometry can alleviate deleterious effects caused by other, experimentally inaccessible, degrees of freedom. We present an experiment in which spatial mode engineering restores sub-shot noise precision of two-photon interference degraded by residual spectral distinguishability.
    • 14:30 Stephan Götzinger
      Efficient generation and manipulation of photons with single molecules
      I will first discuss our efforts to deterministically generate single photons by using planar dielectric antennas. In the second part I will present experiments where photons and single molecules strongly interact. A single molecule can amplify a weak laser beam and generate nonlinear effects like three-photon amplification and four-wave mixing.
    • 15:00 Jake Iles-Smith
      Phonon limit to simultaneous near-unity efficiency and indistinguishability in semiconductor single photon sources
      We develop a non-Markovian theory describing the role of phonons on the indistinguishability and efficiency of semiconductor single photon sources.
    • 15:20 Thomas Kauten
      Observation of genuine three-photon interference
      In this work we present the experimental demonstration of a three-photon energy-time entanglement realized via cascaded down-conversion in nonlinear crystals. The entanglement was analyzed with three imbalanced Franson interferometers, resulting in a visibility of the three-fold coincidences of (92.7 +/- 4.6)%, with negligible two-photon and single-photon visibility.

      Quantum optical magnetometry for biomedical applications
      We have developed a quantum optical magnetometer which is capable of detecting tiny bio-magnetic fields. In proof-of-principle experiments on isolated animal nerves and hearts, we demonstrate that we can detect nerve impulses and the heartbeat. Possible applications include non-invasive diagnostics of diseases related to the brain, heart and nervous system.
    • 16:30 Fedor Jelezko
      Quantum sensing with diamond qubits
      Novel sensing techniques are at the heart of a wide variety of modern technologies. Nanomedicine, molecular biology, chemistry and material science require the ability to measure properties of matter at the atomic scale. Here we show that diamond spin sensors can provide new tool for sensing at nanoscale. We also show how quantum error correction protocols allows to improve performance of diamond spin magnetometers.

      Quantum communications using semiconductor devices
      Quantum key distribution has the unique advantage of allowing secure communications with long term secrecy. Here I discuss recent work to realise practical and reliable systems that operate with high key rates on data carrying, installed fibres, as well as next generation quantum networks based on entanglement.
    • 09:45 Dirk Englund
      Semiconductor quantum technologies for communications and computing
      The Internet is among the most significant inventions of the 20th Century. We are now poised for the development of a quantum internet to exchange quantum information and distribute entanglement among quantum memories (and ultimately quantum computers) that could be great distances apart. This kind of quantum internet would have a range of applications that aren't possible in a classical world, including long-distance unconditionally-secure communication, certain types of precision sensing and navigation, and distributed quantum computing. But we still need to develop or perfect many types of components and protocols to build such a quantum internet. This talk will consider some of these components, focusing on photonic integrated circuits, diamond spin-based quantum memories, and prototype networks. Specifically, the first part of this talk will review our recent progress in adapting one of the leading PIC architectures—silicon photonics—for different types of quantum secure communications protocols. The second part of the talk will consider how photonic integrated circuits technology may extend the reach of quantum communications through all-optical and memory-based quantum repeaters, as well as extensions to modular quantum computers.

      Quantum-limited single molecule sensing: Probing nanoscale biological machinery in its native state
      We introduce a new optical nanofibre-based biosensor that, for the first time, reaches the quantum noise limit. We achieve state-of-the-art sensitivity, tracking single 3.5 nm unlabelled biomolecules with a four order-of-magnitude reduction in optical intensity. This provides a pathway to explore the machinery of life without labels or photochemical damage.

    • 11:45 Giacomo De Palma
      Gaussian states minimize the output entropy of one-mode quantum Gaussian channels
      We prove the longstanding conjecture stating that Gaussian input states minimize the output entropy of one-mode quantum Gaussian channels for fixed input entropy. Our result is crucial to prove the converse theorems for both the triple trade-off region and the capacity region for broadcast communication of the noiseless Gaussian amplifier.
    • 12:05 Nathan Walk
      Composably secure time-frequency quantum key distribution
      We present a composable, finite-size security proof, valid against arbitrary attacks, for high dimensional time-frequency quantum key distribution. Combining advances in entropic uncertainty relations with decoy state analysis, our proof predicts key rates of Mbits/s over metropolitan distances (40 km) and maximum transmission distances of up to 140 km.
    • 12:25 Raj Patel
      An experimental quantum Bernoulli factory
      The Bernoulli factory is an algorithm which takes a sequence of Bernoulli random variables (or coin flips) and outputs a new function. We report an experiment using linear optics which demonstrates a clear quantum advantage in resource consumption when coins exist in superpositions and exhibit non-classical correlations.

    • 09:45 Simon Gröblacher
      Quantum experiments exploiting the radiation pressure interaction between light and matter
      Mechanical oscillators coupled to light via the radiation pressure force have attracted significant attention over the past years for allowing tests of quantum physics with massive objects and for their potential use in quantum information processing. Recently demonstrated quantum experiments include entanglement and squeezing of both the mechanical and the optical mode. So far these quantum experiments have almost exclusively operated in a regime where the light field oscillates at microwave frequencies. Here we would like to discuss recent experiments where we demonstrate non-classical mechanical states by coupling a mechanical oscillator to single optical photons. These results are a promising route towards using mechanical systems as quantum memories, for quantum communication purposes and as light-matter quantum interfaces.
    • 10:15 Marco Bellini
      Measurement-induced quantum state engineering and emulation of strong optical nonlinearities
      Appropriate combinations of elementary quantum operations can faithfully emulate the effect of a strong Kerr nonlinearity on weak states of light. We experimentally demonstrate a nonlinear phase shift at the single-photon level by using coherent states as probes and full quantum tomography of the output states.

      Testing fully quantum repeaters on a quantum internet
      A future quantum internet connects small quantum processors by long distance quantum communication. Possibly the most well known application of quantum communication is quantum key distribution, but many other interesting applications already exist. Here, we propose stages towards the development of a full blown quantum internet, where each stage is distinguished by the successively larger type of applications that it supports. We continue by presenting a test to assess the performance of quantum repeaters for transmitting qubits, rather than key bits, which is required by many protocols.
    • 11:45 Sebastian Steinlechner
      Quantum-dense metrology
      Quantum-dense metrology (QDM) enables simultaneous sensing of two orthogonal phase space projections of a signal by using continuous-variable two-mode entanglement. We show how this approach can be used to achieve sub-shot noise sensitivity even in the presence of classical disturbances, i.e. when the measurement was not even shot-noise limited.
    • 12:05 Milena D'Angelo
      Correlation plenoptic imaging
      Correlation plenoptic imaging pushes imaging to its fundamental limits of both resolution and depth of field, thus enabling diffraction limited imaging with an higly improved DOF. We demonstrate CPI with both chaotic light and entangled photon sources. Both theoretical and experimental results are presented.
    • 12:25 Ivano Ruo-Berchera
      Quantum enhanced absorption measurement and wide field microscopy
      We realized a quantum enhanced wide field microscope exploiting spatially multimode photon number correlations. It provides true (without postselection) sub-shot noise sensitivity for each one of the 10^4 pixels of the image. Absorption sensitivity approaching the best (known) strategy is also reported and discussed.

    • 11:45 Pau Farrera
      Tunable single photon source from an atomic quantum memory for storage in a highly excited Rydberg state
      Strong interaction between two single photons is of broad fundamental interest and would enable several new tools in the field of quantum information. It requires two main ingredients: a strong non-linear medium and a source of single photons compatible with the medium. We show the combination of two such systems.
    • 12:05 Jaromír Fiurášek

      Ultimate precision limit for noisy frequency estimation
      We show how the classical asymptotic scaling of the estimation error can be surpassed using initially entangled states, if a general and realistic kind of noise is considered. The ultimate precision is determined by the short-time behavior, which when departing from a memoryless (LIndbladian) regime leads to super-classical asymptotic resolution.

      Coherent cancellation of measurement back-action-noise in hybrid atom-optomechancis
      Continuous position of force measurements of massive systems are subject to measurement back-action resulting in the standard quantum limit of measurement sensitivity. Current experiments with optomechanical systems reached the regime where measurement sensitivity is limited by back-action-noise. I will discuss an approach towards surpassing the standard quantum limit by coherent cancellation of back noise using an auxiliary system exhibiting an effective negative mass. The auxiliary system is a spin polarized atomic ensemble. This method of back action cancellation was recently demonstrated in the lab of Eugene Polzik (Copenhagen).

      Ultimate precision bounds for the estimation and discrimination of quantum channels
      We consider adaptive metrology and draw a novel connection with teleportation. For teleportation-covariant channels we find that adaptive estimation cannot beat the standard quantum limit, with the quantum Fisher information determined by the Choi-Jamiolkowski matrix. As an example, we establish the ultimate precision for estimating excess noise for quantum cryptography.

Getting there

Venue, access and accommodation

  • Accommodation

    There are not a lot of hotels in the vicinity of DTU, but getting from any of the train stations in central Copenhagen to the conference venue takes 35-40 minutes, so it is perfectly feasible (and perhaps more interesting) to stay in Copenhagen.
    Please note that we do not provide any assistance with booking of hotels or other accommodation.
    That said, here is a list of suggested hotels with convenient access to public transportation.
    Scandic Eremitage, Lyngby
    There is one big hotel in Lyngby, the Scandic Eremitage, 20 minutes walk from the venue.
    We have secured 30 rooms at a discounted price of 1448 DKK single / 1648 DKK double per night for a flexible booking, incl. breakfast. To take advantage of this offer, please fill out this form and return to the hotel at latest 12 May.
    Danhostel Copenhagen City
    The Danhostel Copenhagen City hostel is located in the very center of Copenhagen.
    Conference attendants receive a 10% discount off the regular price. To obtain this discount, send a reservation request to gb@cphhostel.dk which includes the discount booking code DTU17 as well as the following info:
    Name; phone number; email address; dates of your stay; desired room type.
    Suggested hotels in Copenhagen

  • From Copenhagen Airport

    Whether you are going to Copenhagen city centre or directly to DTU, you will take either the train (Öresundstog) towards Copenhagen/Helsingør or the metro towards Vanløse.
