Deriving tight error-trade-off relations for approximate joint measurements of incompatible quantum observables
Cyril Branciard
The quantification of the "measurement uncertainty" aspect of Heisenberg's Uncertainty Principle---that is, the study of trade-offs between accuracy and disturbance, or between acc…
Proposal for demonstrating the Hong-Ou-Mandel effect with matter waves
R. J. Lewis-Swan, K. V. Kheruntsyan
The Hong-Ou-Mandel (HOM) effect is a striking demonstration of destructive quantum interference between pairs of indistinguishable bosons, realised so far only with massless photon…
Generation and stabilization of a three-qubit entangled W state in circuit QED via quantum feedback control
Shang-Yu Huang, Hsi-Sheng Goan, Xin-Qi Li +1
Circuit cavity quantum electrodynamics (QED) is proving to be a powerful platform to implement quantum feedback control schemes due to the ability to control superconducting qubits…
Device-dependent and device-independent quantum key distribution without a shared reference frame
Joshua A. Slater, Cyril Branciard, Nicolas Brunner +1
Standard quantum key distribution (QKD) protocols typically assume that the distant parties share a common reference frame. In practice, however, establishing and maintaining a goo…
Configurable unitary transformations and linear logic gates using quantum memories
G. T. Campbell, O. Pinel, M. Hosseini +3
We show that a set of optical memories can act as a configurable linear optical network operating on frequency-multiplexed optical states. Our protocol is applicable to any quantum…
Universal decoherence due to gravitational time dilation
Igor Pikovski, Magdalena Zych, Fabio Costa +1
The physics of low-energy quantum systems is usually studied without explicit consideration of the background spacetime. Phenomena inherent to quantum theory on curved space-time,…
Generation of distributed entangled coherent states over a lossy environment with inefficient detectors
A. P. Lund, T. C. Ralph, H. Jeong
Entangled coherent states are useful for various applications in quantum information processing but they are are sensitive to loss. We propose a scheme to generate distributed enta…
Investigation of nonlinear effects in Josephson parametric oscillators used in circuit QED
Philip Krantz, Yarema Reshitnyk, Waltraut Wustmann +6
We experimentally study the behavior of a parametrically pumped nonlinear oscillator, which is based on a superconducting λ/4 resonator, and is terminated by a flux-tunable SQUID.…
Experimental Verification of Quantum Discord in Continuous-Variable States
S. Hosseini, S. Rahimi-Keshari, J. Y. Haw +6
We introduce a simple and efficient technique to verify quantum discord in unknown Gaussian states and a certain class of non-Gaussian states. We show that any separation in the pe…
Reduced dimensionality and spatial entanglement in highly anisotropic Bose-Einstein condensates
Alexandre B. Tacla, Carlton M. Caves
We investigate the reduced dimensionality of highly anisotropic Bose-Einstein condensates (BECs) in connection to the entanglement between its spatial degrees of freedom. We argue…
Entangling quantum and classical states of light
Hyunseok Jeong, Alessandro Zavatta, Minsu Kang +5
Entanglement between quantum and classical objects is of special interest in the context of fundamental studies of quantum mechanics and potential applications to quantum informati…
Implementation of a Quantum Metamaterial
Pascal Macha, Gregor Oelsner, Jan-Michael Reiner +7
Manipulating the propagation of electromagnetic waves through sub-wavelength sized artificial structures is the core function of metamaterials. Resonant structures, such as split r…
Spacetime effects on satellite-based quantum communications
David Edward Bruschi, Tim Ralph, Ivette Fuentes +2
We investigate the consequences of space-time being curved on space-based quantum communication protocols. We analyze tasks that require either the exchange of single photons in a…
Joint quantum measurements with minimum uncertainty
Martin Ringbauer, Devon N. Biggerstaff, Matthew A. Broome +3
Quantum physics constrains the accuracy of joint measurements of incompatible observables. Here we test tight measurement-uncertainty relations using single photons. We implement t…
Asymmetric Gaussian harmonic steering in second harmonic generation
M. K. Olsen
Intracavity second harmonic generation is one of the simplest of the quantum optical processes and is well within the expertise of most optical laboratories. It is well understood…
An all-optical feedback assisted steady state of an optomechanical array
Chaitanya Joshi, Uzma Akram, G. J. Milburn
We explore the effect of all-optical feedback on the steady state dynamics of optomechanical arrays arising from various topologies. First we consider an array comprised of a pair…
Quantum nondemolition detection of a propagating microwave photon
Sankar R. Sathyamoorthy, L. Tornberg, Anton F. Kockum +5
The ability to nondestructively detect the presence of a single, traveling photon has been a long-standing goal in optics, with applications in quantum information and measurement.…
Spectral compression of single photons
Jonathan Lavoie, John M. Donohue, Logan G. Wright +2
Photons are critical to quantum technologies since they can be used for virtually all quantum information tasks: in quantum metrology, as the information carrier in photonic quantu…
