Quantum Communication with an Accelerated Partner
T. G. Downes, T. C. Ralph, N. Walk
An unsolved problem in relativistic quantum information research is how to model efficient, directional quantum communication between localised parties in a fully quantum field the…
Noiseless Linear Amplification and Distillation of Entanglement
G. Y. Xiang, T. C. Ralph, A. P. Lund +2
The idea of signal amplification is ubiquitous in the control of physical systems, and the ultimate performance limit of amplifiers is set by quantum physics. Increasing the amplit…
Below-threshold error reduction in single photons through photon distillation
F. H. B. Somhorst, J. Saied, N. Kannan +14
Photonic quantum computers use the bosonic statistics of photons to construct, through quantum interference, the large entangled states required for measurement-based quantum compu…
Quantum simulation of thermodynamics in an integrated quantum photonic processor
F. H. B. Somhorst, R. van der Meer, M. Correa Anguita +16
One of the core questions of quantum physics is how to reconcile the unitary evolution of quantum states, which is information-preserving and time-reversible, with evolution follow…
Simplified intensity- and phase-modulated transmitter for modulator-free decoy-state quantum key distribution
Y. S. Lo, R. I. Woodward, N. Walk +8
Quantum key distribution (QKD) allows secret key exchange between two users with unconditional security. For QKD to be widely deployed, low cost and compactness are crucial require…
Stationary optomechanical entanglement between a mechanical oscillator and its measurement apparatus
C. Gut, K. Winkler, J. Hoelscher-Obermaier +9
We provide an argument to infer stationary entanglement between light and a mechanical oscillator based on continuous measurement of light only. We propose an experimentally realiz…
