Quantum-optimized phase closure for robust interferometric imaging
Zhenning Liu, Emil T. Khabiboulline, Lorcan O. Conlon +7
Closure phase enables imaging with ground-based interferometric arrays by canceling telescope-dependent phase errors due to atmospheric fluctuations. It can be obtained by measurin…
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…
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,…
Bipartite entanglement of noisy stabilizer states through the lens of stabilizer codes
Kenneth Goodenough, Aqil Sajjad, Eneet Kaur +2
Stabilizer states are a prime resource for a number of applications in quantum information science, such as secret-sharing and measurement-based quantum computation. This motivates…
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…
Quantum limits of parameter estimation in long-baseline imaging
Aqil Sajjad, Michael R Grace, Saikat Guha
Distributed aperture telescopes are a well-established approach for boosting resolution in astronomical imaging. However, theoretical limits on quantitative imaging precision, and…
Attaining quantum limited precision of localizing an object in passive imaging
Aqil Sajjad, Michael R Grace, Quntao Zhuang +1
We investigate our ability to determine the mean position, or centroid, of a linear array of equally-bright incoherent point sources of light, whose continuum limit is the problem…
