Resource optimization of quantum-enabled channels using novel modulation schemes

July 21, 2021
Jabir Marakkarakath Vadakkepurayil, FNU Nur Fajar Rizqi Annafianto, Ivan Burenkov, Abdella Battou, Sergey Polyakov
We introduce new practical modulation schemes inspired by the quantum measurement. We experimentally show that our quantum-enabled communication system optimizes the combined resource efficiency (CRE) beyond the classical, shot-noise-limited CRE.

Portable bioluminescent platform for in vivo monitoring of biological processes in non-transgenic animals

May 11, 2021
Aleksey Yevtodiyenko, Arkadiy Bazhin, Pavlo Khodakivskyi, Aurelien Godinat, Gyslain Budin, Marina Kunchulia, Giorgio Pietramaggiori, Sandra Scherer, Elena Goun, Sergey Polyakov, George P. Eppeldauer
Bioluminescent imaging (BLI) is one of the most powerful and widely used preclinical imaging modalities. However, the current technology relies on the use of transgenic luciferase-expressing cells and animals and therefore can only be applied to a limited

Practical quantum-enhanced receivers for classical communication

April 20, 2021
Ivan Burenkov, Jabir Marakkarakath Vadakkepurayil, Sergey Polyakov
Communication is an integral part of human life. Today, optical pulses are the preferred information carriers for long-distance communication. The exponential growth in data leads to a "capacity crunch" in the underlying physical systems. One of the

Coherent optical processes with an all-optical atomic simulator

January 4, 2021
Ivan Burenkov, Sergey Polyakov, Olga Tikhonova, Irina Novikova
We show how novel photonic devices such as broadband quantum memory and efficient quantum frequency transduction can be implemented using three-wave mixing processes in a 1D array of nonlinear waveguides evanescently coupled to nearest neighbors. We do

Experimental demonstration of the near-quantum optimal receiver

November 19, 2020
Jabir Marakkarakath Vadakkepurayil, Ivan Burenkov, FNU Nur Fajar Rizqi Annafianto, Abdella Battou, Sergey Polyakov
We implement the cyclic quantum receiver based on the theoretical proposal of Roy Bondurant and demonstrate experimentally below the shot-noise limit (SNL) discrimination of quadrature phase-shift keying signals (PSK). We also experimentally test the

FPGA Implementation of a Low Latency and High SFDR Direct Digital Synthesizer for Resource-Efficient Quantum-Enhanced Communication

October 15, 2020
FNU Nur Fajar Rizqi Annafianto, Jabir Marakkarakath Vadakkepurayil, Ivan Burenkov, Hasan Urgurdag, Abdella Battou, Sergey Polyakov
In most modulation schemes for a telecommunication system, a fast and efficient sinusoidal signal generator is needed. Here we report on an FPGA implementation of a versatile CORDIC Based Direct Digital Synthesizer (DDS). Most commercial lightwave

Time-Resolving Quantum Measurement Enables Energy-Efficient, Large-Alphabet Communication

September 21, 2020
Ivan Burenkov, Jabir Marakkarakath Vadakkepurayil, Abdella Battou, Sergey Polyakov
Information exchange requires a measurement of physical states. Because quantum measurements enable accuracy beyond the classical shot-noise limit, they are successfully used to develop measurement tools and applications. In particular, quantum-measurement

Electromagnetically induced transparency in inhomogeneously broadened solid media

May 15, 2019
Kumel H. Kagalwala, Fan Haoquan, Sergey Polyakov, Alan L. Migdall, Elizabeth A. Goldschmidt
We study, theoretically and experimentally, electromagnetically induced transparency (EIT) in two di erent solid-state systems. Unlike many implementations in homogeneously broadened media, these systems exhibit inhomogeneous broadening of their optical

Effects of resonant-laser excitation on the emission properties in a single quantum dot

March 27, 2018
Sergey Polyakov, Vivien Loo, Edward Flagg, Glenn S. Solomon, Olivier Gazzano, Tobias Huber
While many solid-state emitters can be optically excited non-resonantly, resonant excitation is necessary for many quantum information protocols as it often maximizes the non-classicality of the emitted light. Here, we study the resonance fluorescence in a

Quantum receiver for large alphabet communication

February 21, 2018
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
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
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

May 3, 2017
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

Full statistical mode reconstruction of a light field via a photon-number resolved measurement

May 2, 2017
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

November 15, 2016
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

July 9, 2015
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

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

December 10, 2014
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

Photomultiplier tubes

November 29, 2013
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
