Experimental test of an event-based corpuscular model modification as an alternative to quantum mechanics

February 13, 2013
Author(s)
Giorgio Brida, Ivo P. Degiovanni, Marco Genovese, Alan L. Migdall, Fabrizio Piacentini, Sergey Polyakov, Paola Traina
We present the first experimental test that distinguishes between an Event-Based Corpuscular Model (EBCM)9) of the interaction of photons with matter and quantum mechanics. The test looks at the interference that results as a single photon passes through a

Dynamics of a pulsed single photon source

December 18, 2012
Author(s)
Sergey V. Polyakov, Edward B. Flagg, Tim O. Thomay, Glenn S. Solomon
We propose and demonstrate a method for an independent verification of a degree of single photon purity and coherence applicable for all single-photon emitters used in pulsed mode. Using two-time second-order correlation measurements, we reconstruct the

Dynamics of the non-classical light from a single solid-state quantum emitter

October 18, 2012
Author(s)
Edward B. Flagg, Sergey Polyakov, Tim O. Thomay, Glenn S. Solomon
We measure the dynamics of a non-classical optical field using two-time second-order correlations in conjunction with pulsed excitation. The technique quantifies single-photon purity and coherence during the excitation-relaxation cycle of an emitter, which

Ancilla assisted calibration of a measuring apparatus

June 19, 2012
Author(s)
Alan L. Migdall, Giorgio Brida, L. Ciavarella, Ivo P. Degiovanni, Marco Genovese, M. G. Mingolla, M. G. A. Paris, Fabrizio Piacentini, Sergey Polyakov
The rapid development of quantum systems has enabled a wide range of novel and innovative technologies, from quantum information processing to quantum etrology and imaging [113], mainly based on optical systems. Precise characterization techniques of

M-ary state phase-shift keying discrimination below the homodyne limit

December 22, 2011
Author(s)
Francisco E. Becerra Chavez, Jingyun Fan, Gerald Baumgartner, Sergey V. Polyakov, Julius Goldhar, Jonathan Kosloski, Alan L. Migdall
We investigate a strategy for M-ary discrimination of nonorthogonal phase states with error rates below the homodyne limit. This strategy uses feed forward to update a reference field and Signal nulling for the state discrimination. We experimentally

Coalescence of Single Photons Emitted by Disparate Single Photon Sources: The Example of InAs Quantum Dots and Parametric Down-Conversion Sources

October 5, 2011
Author(s)
Sergey V. Polyakov, Andreas Muller, Alexander E. Ling, Natalia B. Rutter, Edward B. Flagg, Edward Van Keuren, Alan L. Migdall, Glenn S. Solomon
In quantum mechanics, particles in identical states are indistinguishable, giving rise to effects with no classical analog. Single photons produced by fundamentally dissimilar physical processes will in general not be indistinguishable. We show how photons

State Discriminiation Signal Nulling Receivers

September 6, 2011
Author(s)
Francisco E. Becerra Chavez, Jingyun Fan, Gerald Baumgartner, Sergey V. Polyakov, Julius Goldhar, Jonathan Kosloski, Alan L. Migdall
Optimized state-discrimination receiver strategies for nonorthogonal states can improve the capacity of the communication channels operating with error rates below the ones corresponding to conventional receivers. Coherent signal-nulling receivers use a

Single-Photon Sources and Detectors

July 27, 2011
Author(s)
M D. Eisaman, Jingyun Fan, Alan L. Migdall, Sergey Polyakov
We review the current status of single-photon-source and single-photon-detector technologies operating at wavelengths from the ultraviolet to the infrared. We discuss applications of these technologies to quantum communication, a field that is currently

Indistinguishability of single photons from dissimilar single-photon sources

June 14, 2011
Author(s)
Sergey V. Polyakov, Glenn S. Solomon, Edward B. Flagg, Alan L. Migdall, Andreas Muller
In quantum mechanics, particles in identical states are indistinguishable, giving rise to effects with no classical analog. For instance, the bosonic nature of light insures that upon interference two indistinguishable photons will coalesce into a single

Introduction to special issue on single-photon technologies

March 10, 2011
Author(s)
Alan L. Migdall, Sergey V. Polyakov, Jingyun Fan, Ivo P. Degiovanni, Jessica Cheung
This special issue accompanies the 4th international conference on single-photon technologies held at the National Institute of Standards and Technology (NIST) Boulder in November 2009. This community has met every two years at national metrology

Experimental realization of a low-noise heralded single photon source

January 17, 2011
Author(s)
Alan L. Migdall, Sergey V. Polyakov, Marco Genovese, Fabrizio Piacentini, I. Ruo Berchera, Ivo P. Degiovanni, Giorgio Brida
We present a heralded single-photon source with a much lower level of unwanted background photons in the output channel by using the herald photon to control a shutter in the heralded channel. The shutter is implemented using a simple field programmable
