Optimal qubit circuits for quantum-enhanced telescopes
Robert Czupryniak, John Steinmetz, Paul G. Kwiat +1
We propose two optimal phase-estimation schemes that can be used for quantum-enhanced long-baseline interferometry. By using distributed entanglement, it is possible to eliminate t…
Continuous measurement of a qudit using dispersively coupled radiation
John Steinmetz, Debmalya Das, Irfan Siddiqi +1
We analyze the continuous monitoring of a qudit coupled to a cavity using both phase-preserving and phase-sensitive amplification. The quantum trajectories of the system are descri…
Enhanced on-chip frequency measurement using weak value amplification
John Steinmetz, Kevin Lyons, Meiting Song +2
We present an integrated design to precisely measure optical frequency using weak value amplification with a multi-mode interferometer. The technique involves introducing a weak pe…
