Resource optimization of quantum-enabled channels using novel modulation schemes

July 21, 2021
Author(s)
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

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

April 20, 2021
Author(s)
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

Author(s)
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

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

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
Author(s)
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
Author(s)
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
Author(s)
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
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

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

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
