Attaining Fundamental Limits of Multiparameter Incoherent Optical Imaging Using Joint-Detection Quantum Measurements
Nico Deshler, Aakash Warke, Michael R. Grace +2
Resolving extended incoherent objects below the diffraction limit poses an application-rich imaging challenge whose solution may enable a new generation of observational instrument…

Quantum-limited imaging using diffractive optical neural networks
Aakash Warke, Aonan Zhang, A. I. Lvovsky
We cast general imaging as multiparameter quantum estimation of band-limited spatial-frequency amplitudes. For separable (single-copy) measurements, we compute precision limits usi…

Photonic Quantum Receiver Attaining the Helstrom Bound
Aakash Warke, Janis Nötzel, Kan Takase +6
We propose an efficient decomposition scheme for a quantum receiver that attains the Helstrom bound in the low-photon regime for discriminating binary coherent states. Our method,…
