Abstract

We report a weak-pulse implementation of SARG04 quantum cryptography protocol in free-space. The shifted key generation rate of 22 k bit per second and quantum bit error rate of 4% have been demonstrated. We have also studied the long-distance capability of the QKD system by adding optical losses to the quantum channel.

High-Speed Free-Space Quantum Key Distribution

Ricardo Figueiredo Ferreira

The goal of cryptography is to encode data in such a way that no one can decode it unless they are the intended recipient. With the emergence of quantum computing, classical cryptography is not reliable enough to protect sensitive information. Nevertheless, there are alternatives. Quantum Key Distribution (QKD) is a method to secure communication based on the laws of quantum physics. Due to being impossible to measure the quantum state of a system without disturbing it, QKD provides a way to communicate between two parties while being, in theory, immune to eavesdropping. In this work, a free-space high-speed QKD setup is proposed, with the objective of implementing the polarization three-state one-decoy variant of the BB84 protocol. An assessment of the best type of laser diode to use for free-space QKD is made between several options. The system’s performance was assessed, incorporating a quantitative analysis of system losses and an estimation of the number of photons traversing the quantum channel. The system achieved a Quantum Bit Error Rate (QBER) of 1.58% for the Z basis and 1.46% for the X basis, for an average reception of two photons per pulse. Preliminary QBER measurements were also undertaken in the context of Quantum Keyless Private Communication protocols, focusing on the average number of photons per pulse.

Implementation of two-way free space quantum key distribution

We report an implementation of a two-way, four-state quantum key distribution (QKD) protocol (namely, the LM05 protocol) over a free space medium. A stable quantum bit error rate of 3.34% and maximum tolerable channel loss for secure key generation of 5.68 dB in the absence of a photon number splitting attack were recorded. The result strongly indicates the feasibility of a two-way QKD protocol implementation over a free space medium.

An experimental comparison of BB84 and SARG04 quantum key distribution protocols

Youn-Chang Jeong, Yong‐Su Kim, Yoon-Ho Kim

SARG04 uses the same quantum states and the same measurement bases with BB84 protocol, but SARG04 can generate secret keys from two-photon pulses when BB84 cannot. We report the implementation of BB84 and SARG04 protocols using a polarization-encoded weak coherent pulse with an optical fiber quantum channel. We have experimentally investigated the secret key rate of BB84 and SARG04 protocols, and BB84 gave a higher secret key rate than SARG04.

Implementation of polarization-coded free-space BB84 quantum key distribution

Y. S. Kim, Y. -C. Jeong, Y. S. Kim

We report on the implementation of a Bennett-Brassard 1984 quantum key distribution protocol over a free-space optical path on an optical table. Attenuated laser pulses and Pockels cells driven by a pseudorandom number generator are employed to prepare polarization-encoded photons. The sifted key generation rate of 23.6 kbits per second and the quantum bit error rate (QBER) of 3% have been demonstrated at the average photon number per pulse μ = 0.16. This QBER is sufficiently low to extract final secret keys from shared sifted keys via error correction and privacy amplification. We also tested the long-distance capability of our system by adding optical losses to the quantum channel and found that the QBER remains the same regardless of the loss.

Practical free space quantum cryptography

A successful free space quantum cryptography experiment over a distance of 500 m using the BB84 protocol is reported. The obtained bit error rates of this experiment using faint coherent pulses with an average photon number ranging from 0.1 to 1.0 was measured to be below 3 percent for experiments carried out during night, leading to average raw key rates (before error correction and privacy amplification) of 50 kBits per second.

The paper reports on a free space quantum cryptography experiment over a distance of 24.3 km using a BB84 protocol between the summits of two mountains. The obtained bit error rates in this experiment using faint coherent pulses with an average photon number ranging from 0.1 to 0.7 was measured to range from 3 to 5 percent for experiments carried out during night, leading to raw key rates (before error correction and privacy amplification) of 1500 bits per second.
