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

October 15, 2020
Author(s)
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

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

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

May 3, 2017
Author(s)
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
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
