Practical single sideband modulation scheme for free-space quantum cryptography

Abstract

Quantum key distribution (QKD) is a new technique using physics laws for securing key exchanges. Here we report a new phase-encoding technique adapted to free-space communications. The method combines a direct-modulation scheme with a WDM synchronisation allowing to achieve a reduced size and stabilized system.

Direct intensity and phase modulation for quantum key distribution transmitters

Hui Liu, Gleb Nazarikov, Idelfonso Tafur Monroy

The decoy-state method serves as a cornerstone for practical quantum key distribution (QKD) with inherent immunity to photon-number-splitting attacks. Leveraging optical injection locking, we propose a directly modulated light source with a scheme that simultaneously generates intensity- and phase-modulated signals without external modulators. Removing external modulators eliminates modulator-related side-channel vulnerabilities, fundamentally enhancing QKD security. Integrated into a high-speed phase-encoding BB84 system with optimized one-decoy protocol and finite-size analysis, our system achieves positive key rates up to 20 dB channel loss (100 km fiber) with commercial InGaAs single-photon detectors, reducing transmitter complexity while ensuring security for practical QKD applications.

Free-space quantum cryptography in the H-alpha Fraunhofer window

Daniel J. Rogers, Joshua C. Bienfang, Alan Mink +7 more

Free-space Quantum key distribution (QKD) has shown the potential for the practical production of cryptographic key for ultra-secure communications. The performance of any QKD system is ultimately limited by the signal to noise ratio on the single-photon channel, and over most useful communications links the resulting key rates are impractical for performing continuous one-time-pad encryption of today's broadband communications. We have adapted clock and data recovery techniques from modern telecommunications practice, combined with a synchronous classical free-space optical communications link operating in parallel, to increase the repetition rate of a free-space QKD system by roughly 2 orders of magnitude over previous demonstrations. We have also designed the system to operate in the H-alpha Fraunhofer window at 656.28 nm, where the solar background is reduced by roughly 7 dB. This system takes advantage of high efficiency silicon single-photon avalanche photodiodes with <50ps timing resolution that are expected to enable operation at a repetition rate of 2.5 GHz. We have identified scalable solutions for delivering sustained one-time-pad encryption at 10 Mbps, thus making it possible to integrate quantum cryptography into first-generation Ethernet protocols.

Long-distance QKD transmission using single-sideband detection scheme with WDM synchronization

O.L. Guerreau, Jean-Marc Mérolla, Alexandre Soujaeff +3 more

We report a long-distance, polarization insensitive, quantum key distribution scheme using single-sideband (SSB) detection. The method uses an amplitude modulation to transmit photon in sidebands. The system acts as a fainted laser diode whose information quantum state is encoded in the phase difference between the main peak and its sidebands. Using the dispersion properties of the fiber, the relative phase between interacting quantum states can be reliably controlled by sending a reference signal over the physical link that transmits the quantum signal. Therefore, photon detection can be performed very accurately over long distances. Stability of the synchronization technique with respect to optical path variation is also discussed. The reconciliation process uses a LAN connection as public channel. Experiments were carried out in the C-band telecom window (1550 nm), over a 40-km standard single-mode fiber spool as well as over a 10-km deployed fiber.

Present and future free-space quantum key distribution

J. E. Nordholt, Richard Hughes, George L. Morgan +2 more

Free-space quantum key distribution (QKD), more popularly know as quantum cryptography, uses single-photon free-space optical communications to distribute the secret keys required for secure communications. At Los Alamos National Laboratory we have demonstrated a fully automated system that is capable of operations at any time of day over a horizontal range of several kilometers. This has proven the technology is capable of operation from a spacecraft to the ground, opening up the possibility of QKD between any group of users anywhere on Earth. This system, the prototyping of a new system for use on a spacecraft, and the techniques required for world-wide quantum key distribution will be described. The operational parameters and performance of a system designed to operate between low earth orbit (LEO) and the ground will also be discussed.

Fast Quantum Cryptography System Using Single Photon Communication

Akihisa Tomita, Akio Tajima

Quantum Key Distribution (QKD) systems based on single photon transmission can generate unconditionally secure common key between remote users. Improvement of QKD performance, particularly on key generation rate, has been required to meet current network traffic. High key generation rate is realized by increasing photon detection rate and by reducing error rate. Therefore, a high-speed QKD system should be equipped with low loss receivers with high visibility, highly efficient photon detectors with small dark count probability, and a stable clock synchronization system with low stray light to the quantum signals. A solution for these issues are given by employing planar lightwave circuit interferometers, single photon detection circuits and modules, and clock synchronization based on Wavelength Division Multiplexing (WDM) technique.

Quantum key secure communication protocol via enhanced superdense coding

Mario Mastriani

In the last decades, Quantum Cryptography has become one of the most important branches of Quantum Communications with a particular projection over the future Quantum Internet. It is precisely in Quantum Cryptography where two techniques stand out above all others: Quantum Key Distribution (QKD), and Quantum Secure Direct Communication (QSDC). The first one has four loopholes relating to the exposure of the key at all points in the communication system, while the second has clear practical implementation problems in all its variants currently in use. Here, we present an alternative to QKD and QSDC techniques called quantum key secure communication (QKSC) protocol with a successful implementation on two free access quantum platforms.
