Twin-Field (TF) quantum key distribution (QKD) is a major candidate to be the new benchmark for far-distance QKD implementations, since its secret key rate can overcome the repeaterless bound by means of a simple interferometric measurement. Many variants of the original protocol have been recently proven to be secure. Here, we focus on the TF-QKD type protocol proposed by Curty et al [preprint arXiv:1807.07667], which can provide a high secret key rate and whose practical feasibility has been… Expand

Simple method for asymmetric twin-field quantum key distribution
Twin-Field quantum key distribution (TF-QKD) can beat the linear bound of repeaterless QKD systems. After the proposal of the original protocol, multiple papers have extended the protocol to proveExpand
Conference key agreement with single-photon interference
This work generalizes the main idea of the TF-QKD protocol to the multipartite scenario, by devising a conference key agreement (CKA) where the users simultaneously distill a secret conference key through single-photon interference, and employs for the first time a W-class state as its entanglement resource.

Finite-key analysis of asymmetric phase-matching quantum key distribution with unstable sources
The effects of asymmetric channels on the PM-QKD protocol are discussed; to reach a much better performance and achieve a higher key rate, the intensity must be optimized to compensate for channel asymmetry. Expand

Differential Phase Shift Quantum Secret Sharing Using a Twin Field with Asymmetric Source Intensities
This work presents a differential phase shift quantum secret sharing protocol with asymmetric source intensities and gives the security proof of the protocol against individual attacks and can provide a high key rate even when the difference is quite large and has great robustness against finite-key effects.

This paper considers a tripartite QCKA protocol utilizing the idea of sending-or-not-sending twin-field scheme and proposes a high-efficiency QCKA over asymmetric channels by removing the symmetry parameters condition and provides a composable finite-key analysis with rigorous security proof against general attacks.

The sending-or-not-sending (SNS) protocol of the twin-field quantum key distribution (TFQKD) can tolerant large misalignment error and its key rate can exceed the bound of repeaterless QKD. But theExpand
A quantum leap in security
One-photon and two-photon interferences have recently led researchers to develop new classes of quantum cryptographic protocols.


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. Expand
Simple security proof of twin-field type quantum key distribution protocol
It is demonstrated that the secure key rate of this protocol has a square-root improvement over the point-to-point private capacity, as conjectured by the original TF QKD. Expand
Twin-Field Quantum Key Distribution without Phase Postselection
Counterintuitively, it is found that in TF-QKD, beating the rate-loss limit is still possible even if phase randomization and post-selection in the coding mode are both removed, which means the final secure key rate $R=O(\sqrt{\eta})$. Expand

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.
