A photon transport problem with a time-dependent point source [PDF]

, 2009
We consider a time-dependent problem of photon transport in an interstellar cloud with a point photon source modeled by a Dirac δ functional. The existence of a unique distributional solution to this problem is established by using the theory of ...

Quantum detector tomography of a time-multiplexed superconducting nanowire single-photon detector at telecom wavelengths [PDF]

, 2013
Superconducting nanowire single-photon detectors (SNSPDs) are widely used in telecom wavelength optical quantum information science applications. Quantum detector tomography allows the positive-operator-valued measure (POVM) of a single-photon detector ...

Effect of loss on multiplexed single-photon sources

New Journal of Physics, 2015
An on-demand single-photon source is a key requirement for scaling many optical quantum technologies. A promising approach to realize an on-demand single-photon source is to multiplex an array of heralded single-photon sources using an active optical ...
