The key rate overcomes the repeaterless secret key capacity bound limit at channel losses of 85 dB, corresponding to 530 km of ultralow-loss optical fibre, and represents a major step in promoting quantum communications as a dependable resource in today's world.

Experimental Mode-Pairing Quantum Key Distribution Surpassing the Repeaterless Bound

Quantum key distribution (QKD) provides information-theoretic security for communication. The mode-pairing (MP) protocol emerges as a promising solution for long-distance QKD by eliminating the need

Twin-field quantum key distribution over 830-km fibre

An experimental QKD system that could tolerate a channel loss beyond 140 dB and obtain a secure distance of 833.8 km is presented, setting a new record for fibre-based QKKD and marking a breakthrough towards building reliable and efficient terrestrial quantum-secure networks over a scale of 1,000‬km.

Asymmetric twin-field quantum key distribution

This work derives new analytical bounds when the parties use either two, three or four independent decoy intensity settings each, thus providing sub-optimal key rates in asymmetric-loss scenarios and shows that the protocol is robust against uncorrelated intensity fluctuations affecting the parties’ lasers.

Quantum key distribution (QKD) aims to generate secure private keys shared by two remote parties. With its security being protected by principles of quantum mechanics, some technology challenges

Coherent phase transfer for real-world twin-field quantum key distribution

A setup for twin-field QKD is demonstrated which extends the coherence times by three orders of magnitude and reduces the quantum-bit-error-rate contributed by channel length variations to <1%, representing an effective solution for real-world quantum communications.

Practical decoy-state method for twin-field quantum key distribution

Simulations show that two decoy intensity settings are enough to beat the point-to-point private capacity of the channel, and that the use of four decoys is already basically optimal, in the sense that it almost reproduces the ideal scenario of infinite decoys.

Twin-field quantum key distribution without optical frequency dissemination

Twin-field (TF) quantum key distribution (QKD) has rapidly risen as the most viable solution to long-distance secure fibre communication thanks to its fundamentally repeater-like rate-loss scaling.

Experimental quantum key distribution with uncharacterized sources and projective measurements.

This work reports an experimental decoy-state QKD demonstration with uncharacterized encoding sources, which only requires that the encoding states are two-dimensional and the measurement operation of the receiver is loosened to be projective measurements.

Free-Space Twin-Field Quantum Key Distribution

Twin-field quantum key distribution (TF-QKD) elevates the secure key rate from a linear to a square-root dependence on channel loss while preserving measurement-device-independent security. This

Fundamental rate-loss tradeoff for optical quantum key distribution

It is shown that the secret key agreement capacity of a lossy and noisy optical channel assisted by unlimited two-way public classical communication is limited by an upper bound that is solely a function of the channel loss, regardless of how much optical power the protocol may use.

Overcoming the rate–distance limit of quantum key distribution without quantum repeaters

This work introduces an alternative scheme for QKD whereby pairs of phase-randomized optical fields are first generated at two distant locations and then combined at a central measuring station, enabling a form of quantum key distribution that can exceed the secret-key capacity without using quantum repeaters and that has security independent of the measuring devices.
