Comment on "Quantum Limits to Incoherent Imaging are Achieved by Linear Interferometry"
George Brumpton, Aiman Khan, Helia Hooshmand +2
We show that the construction of the linear interferometer in the Supplemental Material of arXiv:1909.09581 is flawed, leading to a generally suboptimal solution. We then provide t…
Multiphoton Hong-Ou-Mandel Interference Enables Superresolution of Bright Thermal Sources
Aiman Khan, Danilo Triggiani, Vincenzo Tamma
We present a quantum optical scheme for imaging transversely displaced thermal sources of arbitrary intensities by employing multiphoton interference with a reference single-photon…
Pulsed single-photon spectroscopy of an emitter with vibrational coupling
Sourav Das, Aiman Khan, Elnaz Darsheshdar +2
We analytically derive the quantum state of a single-photon pulse scattered from a single quantum two-level emitter interacting with a vibrational bath. This solution for the quadr…
Optimal quantum spectroscopy using single-photon pulses
Sourav Das, Aiman Khan, Francesco Albarelli +1
We provide the ultimate precision attainable in spectroscopy of a quantum emitter using single-photon pulses. We find the maximum for estimating the linewidth to be independent of…
A tensor network approach to sensing quantum light-matter interactions
Aiman Khan, Francesco Albarelli, Animesh Datta
We present the fundamental limits to the precision of estimating parameters of a quantum matter system probed by light, even when some of the light is lost. This practically inevit…
