Non-Markovian delay-assisted sensing with waveguide-coupled quantum emitters

Prajit Dhara, Isack Padilla, Saikat Guha +2

We show that in a minimal setup of two waveguide-coupled quantum emitters, separated by long distances and subject to an external field, time-delayed feedback can be a resource for…

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…

Towards quantum-enhanced long-baseline optical/near-IR interferometry

Jayadev K. Rajagopal, Ryan M. Lau, Isack Padilla +10

Microarcsecond resolutions afforded by an optical-NIR array with kilometer-baselines would enable breakthrough science. However significant technology barriers exist in transportin…

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,…
