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…
Sensing with Quantum Light: A perspective
Animesh Datta
I present my perspective on sensing with quantum light. I summarise the motivations and methodology for identifying quantum enhancements in sensing over a classical sensor. In the…
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…
On the role of chirping in pulsed single photon spectroscopy
Elnaz Darsheshdar, Aiman Khan, Francesco Albarelli +1
We investigate the precision of estimating the interaction strength between a two-level system (TLS) and a single-photon pulse when the latter is subject to chirping. We consider l…
