Enhancing Optical Imaging via Quantum Computation
Aleksandr Mokeev, Babak Saif, Mikhail D. Lukin +1
Extracting information from weak optical signals is a critical challenge across a broad range of technologies. Conventional imaging techniques, constrained to integrating over dete…
Superadditive Communication with the Green Machine: A Practical Demonstration of Nonlocality without Entanglement
Chaohan Cui, Jack Postlewaite, Babak N. Saif +2
Achieving the ultimate Holevo limit of optical communication capacity requires a joint-detection receiver which makes a collective quantum measurement over multiple modulated symbo…
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,…
