Hybrid Heralded Noiseless Amplification with Finite-Cutoff Quantum Scissors
Haixi Miao, Timothy C. Ralph
A noiseless linear amplifier (NLA) can probabilistically amplify an optical state without the noise required by deterministic phase-insensitive amplification. We study a hybrid amp…
Observing relativistic trajectories of single photons
Sayantan Das, Daniel S. Dahl, Daniel Peace +6
While the standard interpretation of quantum mechanics does not assign definite trajectories to particles, the Bohmian interpretation does. Only recently has an operational method…
Co-transmission of classical data and continuous-variable entanglement over a single quantum channel
Nicholas Zaunders, Timothy C. Ralph
Displacement-based simultaneous quantum-classical communications (SQCC) protocols, as originally proposed, are generally incompatible with the majority of useful quantum communicat…
Can a quantum circuit detect the Unruh effect?
Pravin Kumar Dahal, Timothy C. Ralph, William J. Munro +2
The Unruh effect predicts that an accelerating observer perceives the Minkowski vacuum as a thermal bath, yet direct detection remains experimentally inaccessible. Its timelike cou…
Generalised simultaneous transmission of arbitrary quantum states and classical information
Nicholas Zaunders, Timothy C. Ralph
We present a protocol which allows for arbitrary optical quantum states to simultaneously carry and transmit classical data, without sacrificing the integrity of either the quantum…
Time-energy uncertainty relation from subcycle mode vacuum fluctuations of a quantum field
Achintya Sajeendran, Timothy C. Ralph
The time-energy uncertainty relation is often invoked as a heuristic explanation for virtual particles in interacting quantum field theories. However, this interpretation breaks do…
