Multiplexing photons with a binary division strategy
(Springer, 2013-11)
We present a scheme to produce clock-synchronized photons from a single parametric downconversion source with a binary division strategy. The time difference between a clock and detections of the herald photons determines ...
Performance of a temporally multiplexed single photon source with imperfect devices
(Springer, 2019-10)
Scalable photonic quantum technologies require highly efficient sources of single photons on demand. Although much progress has been done in the field within the last decade, the requirements impose stringent conditions ...
Scheme for sub-shot-noise transmission measurement using a time-multiplexed single-photon source
(Optical Society of America, 2021-09)
Sub-shot-noise performance in transmission measurements can be achieved in optical quantum metrology owing to significantly lower uncertainty in light intensity of quantum beams compared to their classical counterparts. ...
Master equation approach to propagation in nonlinear fibers
(Optical Society of America, 2021-02)
In this Letter, we revisit the quantum theory of propagation in nonlinear fibers. Unlike previous works, we present an effective propagation equation for the reduced density matrix of the complex envelope of the electric ...
Contagem de fótons únicos com CCD em experimentos de óptica quântica
(Universidade Federal de Minas GeraisUFMG, 2017-08-04)
In this work we discuss topics such as the theory of photon detectors, showing its operation mode, characteristics and types. In addition, we also study the quantum detection theory, how photons interact with the detector's ...
ENTANGLEMENT BETWEEN TWO SINGLE-PHOTON SOURCES DUE TO A BEAM SPLITTER
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Física, 2014-07-01)
We consider a quantum dot of frequency w_s embedded in a semiconductor microcavity interacting with an electromagnetic mode of frequency w_a. The cavity is subject to a pumping laser of power W and frequency w_L, and to ...
Beat structure in the solution of scattering problems with nondecaying sources*
(Springer, 2017-03)
Abstract: In this contribution we study mathematical properties of scattering solutions of Schrödinger-type equations with nondecaying, outgoing type, driven terms. We analyze in some details the two-body frame, where an ...
