Quantum receiver for large alphabet communication

February 21, 2018
Author(s)
Sergey Polyakov, Ivan Burenkov, Olga Tikhonova
Quantum mechanics allows measurements that surpass the fundamental sensitivity limits of classical methods. To benefit from the quantum advantage in a practical setting, the receiver should use communication channel resources optimally; this can be done

Simultaneous, Full Characterization of a Single-Photon State

November 15, 2017
Author(s)
Tim O. Thomay, Sergey Polyakov, Elizabeth A. Goldschmidt, Glenn S. Solomon, Olivier Gazzano, Vivien Loo
As single-photon sources become more mature and are used more often in quantum information, communications, and measurement applications, their characterization becomes more important. Single-photon-like light is often characterized by its brightness, as

Software for complete mode structure analysis of a light field

June 26, 2017
Author(s)
Ivan A. Burenkov, Sergey V. Polyakov
We present a software package aimed at simulating photon-number probability distributions of a range of naturally occurring classical and non-classical states of light. This software can generate arbitrary probability distributions based on the known mode

Coherent quantum frequency bridge: phase preserving, nearly-noiseless parametric frequency converter

Ivan A. Burenkov, Yu-Hsiang Cheng, Tim O. Thomay, Glenn S. Solomon, Alan L. Migdall, Thomas Gerrits, Adriana E. Lita, Sae Woo Nam, Lynden K. Shalm, Sergey V. Polyakov
We characterize an efficient and nearly-noiseless parametric frequency upconverter. The ultra- low noise regime is reached by the wide spectral separation between the input and pump frequencies and the low pump frequency relative to the input photons. The

May 2, 2017
Author(s)
Ivan A. Burenkov, Sergey V. Polyakov, Thomas Gerrits, Timothy J. Bartley, Georg Harder, Christine Silberhorn, Ankita Sharma, Elizabeth A. Goldschmidt
We present a method to reconstruct the mode structure and optical losses of multimode conjugated optical fields using an experimentally measured joint photon-number probability distribution. We demonstrate nearly-perfect reconstruction of a multimode field

Scalable, chip-based optically-controlled gates for quantum information processing

November 15, 2016
Author(s)
Sergey V. Polyakov, Ivan Burenkov, Olga Tikhonova
Here we present a simple and robust method to build on-the-fly configurable quantum gates based on photonic exchange between quantum nodes. The idea is based on a high reflectivity of Bragg grating structures near resonant wavelengths. The control is

Statistically background-free, phase-preserving parametric up-conversion with faint light

July 9, 2015
Author(s)
Yu-Hsiang Cheng, Tim O. Thomay, Glenn S. Solomon, Alan L. Migdall, Sergey Polyakov
We demonstrate phase preservation in a frequency up-conversion process at the single-photon level. This phase preservation enables the applications of frequency conversion of entangled photon pairs. Periodically poled lithium niobate waveguides and a 1550

Single-Photon Detector Calibration

July 7, 2015
Author(s)
Sergey V. Polyakov
In this chapter we introduce the set of detector properties, common to most contemporary detectors, that should be determined for a complete characterization. Then we introduce methods for detector characterization, and finally we present practical recipes

Sergey V. Polyakov, Fabrizio Piacentini, Filippo Levi, A Avella, M Lopez, Stefan Kuck, Ivo P. Degiovanni, Giorgio Brida, Marco Genovese
Here we present a reconstruction of the Positive Operator-Value Measurement of a photon-number-resolving detector comprised of three 50:50 beamsplitters in a tree configuration, terminated with four single-photon avalanche detectors.

Author(s)
Sergey V. Polyakov, Alan L. Migdall, Elizabeth A. Goldschmidt, Giorgio Brida, Stefan Kuck, Fabrizio Piacentini, Ivo P. Degiovanni, I. Ruo Berchera, Marco Genovese
We build upon our newly developed mode reconstruction technique that takes advantage of higher-order photon number statistics and propose new experiments.

Experimental Bounds on Classical Random Field Theories

December 10, 2014
Author(s)
Joffrey K. Peters, Sergey V. Polyakov, Jingyun Fan, Alan L. Migdall
Alternative theories to quantum mechanics motivate important fundamental tests of our understanding and description of the smallest physical systems. Here we place experimental limits on those classical field theories which result in power-dependent

Hybrid Detectors

November 29, 2013
Author(s)
Sergey V. Polyakov, Alan L. Migdall, Franco N. Wong, Ivo P. Degiovanni, Ian Walmsley, Hendrik B. Coldenstrodt-Ronge
We present an overview of e orts to improve photon-counting detection systems through the use of hybrid detection techniques such as spatial- and time-multiplexing of conventional detectors, and frequency up-conversion. We review the basic operation for

Photomultiplier tubes

November 29, 2013
Author(s)
Sergey V. Polyakov
Photomultiplier tubes (PMTs), also known as photomultipliers, are remarkable devices. While a PMT was the rst device to detect light at the single photon level, invented more than 80 years ago, they are widely used to this day, particularly in biological

Single-Photon Sources and Detectors Book: Chapter 1: Introduction

November 29, 2013
Author(s)
Joshua C. Bienfang, Jingyun Fan, Alan L. Migdall, Sergey V. Polyakov
In the beginning there was light. And it was good. Not long thereafter people began to look for a comprehensive understanding of its nature. While the publication record starts o a little spotty, in the fth century BC the Greek philosopher Empedocles

Mode reconstruction of a light field by multi-photon statistics
