Extending single-photon optimized superconducting transition edge sensors beyond the single-photon counting regime

May 6, 2012
Author(s)
Thomas Gerrits, Brice R. Calkins, Nathan A. Tomlin, Adriana E. Lita, Alan L. Migdall, Richard P. Mirin, Sae Woo Nam
We illuminate a photon-number-resolving transition edge sensor with strong pulses of light containing up to 6.7 million photons (0.85 pJ per pulse). These bright pulses heat the sensor far beyond its transition edge into the normal resistance regime. We

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

Extending single-photon optimized superconducting transition edge sensors beyond the single-photon counting regime

September 19, 2011
Author(s)
Thomas Gerrits, Brice R. Calkins, Nathan A. Tomlin, Adriana E. Lita, Alan L. Migdall, Sae Woo Nam, Richard P. Mirin
Photon number resolving transition-edge sensors (TES) are the cutting-edge enabling technology for high quantum efficiency photon number counting. The TES developed at NIST reliably show system detection efficiencies of more than 95%, and even approach 99%

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

Polarization-Entangled Photon Pairs From a Periodically Poled Cystalline Waveguide

March 23, 2011
Author(s)
Zachary H. Levine, Jingyun Fan, Jun Chen, Alan L. Migdall
A proposal is made for the generation of polarization-entangled photon pairs from a periodically poled crystal. The theory is formulated in terms of colinear propagation for application to waveguides. The key feature of the theory is the use of type 2

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
