Eliminating photon transport in long-baseline optical interferometry using quantum memories
Yousef K. Chahine, Chaohan Cui, William DeRocco +11
In this paper, we describe the fundamental operating mechanisms of optical interferometry using quantum memory and entanglement. We show how these remove the optical delay line bot…
Fundamental Limit for One versus Two Point Sources Detection using Direct Imaging
Parth Hemant Darekar, Amit Kumar Jha, Michael R. Grace +2
We consider the task of distinguishing between a single weak incoherent optical point source and two weak incoherent optical point sources located symmetrically about the first sou…
Lower bounds on bipartite entanglement in noisy graph states
Aqil Sajjad, Eneet Kaur, Kenneth Goodenough +2
Graph states are a key resource for a number of applications in quantum information theory. Due to the inherent noise in noisy intermediate-scale quantum (NISQ) era devices, it is…
Boosted linear-optical measurements on single-rail qubits with unentangled ancillas
Aqil Sajjad, Isack Padilla, Saikat Guha
Any quantum state of the radiation field, sliced in small non-overlapping space-time bins is a collection of single-rail qubits, each spanning the vacuum and single-photon Fock sta…
Superresolution imaging with entanglement-enhanced telescopy
Isack Padilla, Aqil Sajjad, Babak N. Saif +1
Long-baseline interferometry will be possible using pre-shared entanglement between two telescope sites to mimic the standard phase-scanning interferometer, but without physical be…
Quantum resolution limit of long-baseline imaging using distributed entanglement
Isack Padilla, Aqil Sajjad, Babak N. Saif +1
It has been shown that shared entanglement between two telescope sites can in principle be used to localize a point source by mimicking the standard phase-scanning interferometer,…
