1. Single-photon detection efficiency up to 50% at 1310 nm with an InGaAs/InP avalanche diode gated at 1.25 GHz
Published: 4/10/2013
Authors: Alessandro Restelli, Joshua C Bienfang, Alan L Migdall
Abstract: We describe a gated Geiger-mode single-photon avalanche diode (SPAD) detection system in which both gating and avalanche discrimination are implemented by coherent addition of discrete harmonics of the fundamental gate frequency. With amplitude a ...

2. Experimental demonstration of a receiver beating the standard quantum limit for multiple nonorthogonal coherent-state discrimination
Published: 1/6/2013
Authors: Francisco Elohim Becerra Chavez, Jingyun Fan, Gerald Baumgartner, Julius Goldhar, Jonathan Kosloski, Alan L Migdall
Abstract: The measurement of the state of a quantum system with inherent quantum uncertainty (noise) approaching the ultimate physical limits is of both technological and fundamental interest. Quantum noise prevents any mutually nonorthogonal quantum states ...

3. M-ary state phase-shift keying discrimination below the homodyne limit
Published: 12/22/2011
Authors: Francisco Elohim Becerra Chavez, Jingyun Fan, Gerald Baumgartner, Sergey V Polyakov, Julius Goldhar, Jonathan Kosloski, Alan L Migdall
Abstract: 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 discriminati ...

4. State Discriminiation Signal Nulling Receivers
Published: 9/6/2011
Authors: Francisco Elohim Becerra Chavez, Jingyun Fan, Gerald Baumgartner, Sergey V Polyakov, Julius Goldhar, Jonathan Kosloski, Alan L Migdall
Abstract: 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 us ...

5. Single-Photon Sources and Detectors
Published: 7/27/2011
Authors: M D. Eisaman, Jingyun Fan, Alan L Migdall, Sergey V Polyakov
Abstract: 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 curre ...

6. Introduction to special issue on single-photon technologies
Published: 3/10/2011
Authors: Alan L Migdall, Sergey V Polyakov, Jingyun Fan, Ivo Pietro Degiovanni, Jessica Cheung
Abstract: 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 ins ...

7. Experimental realization of a low-noise heralded single photon source
Published: 1/17/2011
Authors: Alan L Migdall, Sergey V Polyakov, Marco Genovese, Fabrizio Piacentini, I. Ruo Berchera, Ivo P Degiovanni, Giorgio Brida
Abstract: 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 program ...

8. Frequency-bin Entangled Comb of Photon Pairs From a Silicon-on-Insulator Micro-Resonator
Published: 1/13/2011
Authors: Jun Chen, Zachary H Levine, Jingyun Fan, Alan L Migdall
Abstract: We present a quantum-mechanical theory to describe narrow-band photon- pair generation via four-wave mixing in a Silicon-on-Insulator (SOI) micro- resonator. We also provide design principles for efficient photon-pair generation in an SOI mic ...

9. Generation of optical coherent-state superpositions by number-resolved photon subtraction from the squeezed vacuum
Published: 9/9/2010
Authors: Thomas Gerrits, Scott C Glancy, Tracy S. Clement, Brice Robert Calkins, Adriana Eleni Lita, Aaron Miller, Aaron Joseph Miller, Alan L Migdall, Sae Woo Nam, Richard P Mirin, Emanuel H Knill
Abstract: We have created heralded coherent-state superpositions (CSSs) by subtracting up to three photons from a pulse of squeezed vacuum light. To produce such CSSs at a sufficient rate, we used our high-efficiency photon-number-resolving transition edge sen ...

10. Generation of optical Schrödinger cat states by number-resolved squeezed photon subtraction
Published: 7/23/2010
Authors: Thomas Gerrits, Scott C Glancy, Tracy S. Clement, Brice Robert Calkins, Adriana Eleni Lita, Aaron Joseph Miller, Alan L Migdall, Aaron J Miller, Sae Woo Nam, Richard P Mirin, Emanuel H Knill
Abstract: We have generated and measured an approximation of an optical Schrödinger cat state by photon subtraction from squeezed vacuum. Figure 1 shows the experimental scheme. Photons are probabilistically subtracted from squeezed vacuum and detected with a ...
