Abstract

We experimentally demonstrate a quantum-measurement-based receiver for a range of modulation schemes and alphabet lengths in a telecom C-band. We attain symbol error rates below the shot noise limit for all the studied modulation schemes and the alphabet lengths 4≤M≤16. In doing so, we achieve the record energy sensitivity for telecom receivers. We investigate the trade-off between energy and bandwidth use and its dependence on the alphabet length. We identify the combined (energy and bandwidth) resource efficiency as a figure of merit and experimentally confirm that the quantum-inspired hybrid frequency/phase encoding has the highest combined resource efficiency.

A versatile telecom quantum receiver for energy and bandwidth efficient communication

Jabir M. V., N. Fajar R. Annafianto, Ivan A. Burenkov +2 more

Quantum enabled optical receivers can achieve a symbol error rate below the shot noise limit and have been extensively studied at visible wavelengths. Yet, the practical use of a quantum receiver requires the implementation at telecom wavelengths. Here we report a successful implementation of a telecom-enabled, versatile time resolving quantum receiver testbed that enables a range of modulation schemes and supports long communication alphabets. We achieved the record sensitivity for a legacy 4-symbol modulation and implemented other modulations and longer alphabets for the first time by combining a highly efficient single photon detector with the time-resolved receiver design.

Abstract We present a systematic study of quantum receivers and modulation methods enabling resource efficient quantum-enhanced optical communication. We introduce quantum-inspired modulation schemes that theoretically yield a better resource efficiency than legacy protocols. Experimentally, we demonstrate below the shot-noise limit symbol error rates for M ≤ 16 legacy and quantum-inspired communication alphabets using software-configurable optical communication time-resolving quantum receiver testbed. Further, we experimentally verify that our quantum-inspired modulation schemes boost the accuracy of practical quantum measurements and significantly optimize the combined use of energy and bandwidth for communication alphabets that are longer than M = 4 symbols.

Jabir M. V., Ivan A. Burenkov, N. Fajar R. Annafianto +2 more

The exponential growth of the internet is currently fulfilled by optical communication, but photonic communication channels are on the verge of a capacity crunch. We systematically study the use of bandwidth and energy of quantum-enhanced communication channels for classical information with different practical encodings. We introduce hybrid encoding protocols with a simultaneous coherent frequency and phase modulation and optimize them for the most advantageous quantum measurement at the receiver. We experimentally map the energy and bandwidth use for the optimization of practical resource-limited channels using a tabletop platform. We also report the initial progress on developing an integrated telecom testbed.

Quantum coherent frequency-shift keying beyond the standard quantum limit (Conference Presentation)

Ivan A. Burenkov, Sergey V. Polykov

The efficient use of communication channels motivates extensive research in novel communication protocols. Modern communication protocols use large alphabets contain up to a few thousand symbols, thus optimizing the use of power and available frequency space. To date, quantum receivers that discriminate up to approximately 20 symbols were theoretically investigated and receivers with as many as 4 nonorthogonal coherent states have been experimentally demonstrated. However, all heretofore explored quantum receivers suffer from the sensitivity degradation with the alphabet size. Particularly, their Helstrom Bound (HB) nearly reaches the classical standard quantum limit (SQL). Here we introduce an M-ary quantum receiver based on a coherent frequency shift keying (CFSK) protocol with a record power sensitivity, free of the above deficiency. The CFSK not only provides better accuracy for longer alphabets but also allows discrimination with a practically attainable symbol error rate (SER) situated much below the HBs of other encodings for large alphabets. Our receiver operates with a classical transmitter, and with any communication channel, including the existing global fiber network. It can be used to increase the amplification-free range in a network and/or reduce power requirements on the transmitter by more than 1000 times. In addition, the quantum measurement advantage can significantly optimize the use of the frequency space in comparison to classical frequency keying protocols. This advantage can be used in deep-space telecom links to enhance the satellite power budget. In existing fiber network links, quantum CFSK receivers can improve the amplification-free range by approximately the factor of 2.
