Cavity-free scheme for nondestructive detection of a single optical photon

K Xia, M Johnsson, PL Knight, J Twamley - Physical review letters, 2016 - APS
Detecting a single photon without absorbing it is a long-standing challenge in quantum
optics. All experiments demonstrating the nondestructive detection of a photon make use of …

Analytical results for a conditional phase shift between single-photon pulses in a nonlocal nonlinear medium

B Viswanathan, J Gea-Banacloche - Physical Review A, 2018 - APS
It has been suggested that second-order nonlinearities could be used for quantum logic at
the single-photon level. Specifically, successive two-photon processes in principle could …

Self-organization and Fourier selection of optical patterns in a nonlinear photorefractive feedback system

O Sandfuchs, F Kaiser, MR Belić - Physical Review A, 2001 - APS
The formation of patterns in two transverse dimensions in photorefractive two-wave mixing
with a single feedback mirror is investigated theoretically. We perform numerical simulations …

[图书][B] A Study of Optical Nonlinearities at the Single-Photon Level for Quantum Logic

B Viswanathan - 2020 - search.proquest.com
In this dissertation, we shall focus on theoretically studying quantum nonlinear optical
schemes to construct a conditional phase gate at the single-photon level. With an aim to …
