Passive Imaging with Quantum Advantage
Li Gong, Aonan Zhang, Madhura Ghosh Dastidar +2
Far-field optical imaging inevitably involves low-pass spatial filtering, limiting the resolution. Moreover, conventional imaging suppresses high spatial frequency components close…
Signatures of superradiance in intensity correlation measurements in a two-emitter solid-state system
Madhura Ghosh Dastidar, Aprameyan Desikan, Gniewomir Sarbicki +1
We perform intensity correlation () measurements on nitrogen-vacancy (NV) emitters embedded in diamond nanopillars. We observe an increase in transition rates from both…
Using Entangled Generalized Coherent States for Photonic Quantum Metrology
Madhura Ghosh Dastidar, Aprameyan Desikan, Vidya Praveen Bhallamudi
Quantum metrology aims at achieving enhanced performance in measuring unknown parameters by utilizing quantum resources. Thus, quantum metrology is an important application of quan…
Synchronized Bell protocol for detecting non-locality between modes of light
Madhura Ghosh Dastidar, Gniewomir Sarbicki, Vidya Praveen Bhallamudi
In the following paper, we discuss a possible detection of non-locality in two-mode light states in the Bell protocol, where the local observables are constructed using displacemen…
Detecting Entanglement Between Modes of Light
Madhura Ghosh Dastidar, Gniewomir Sarbicki
We consider a subgroup of unitary transformations on a mode of light induced by a Mach-Zehnder Interferometer and an algebra of observables describing a photon-number detector proc…
