Forward-looking criteria for the certification of quantum key distribution (Conference Presentation)
2018
Technological advances in quantum computers and number theory have the potential to compromise the security of existing cryptographic protocols. Quantum key distribution (QKD) offers the possibility of information theoretic security and is theoretically unbreakable. Therefore …

An entangled-LED-driven quantum relay over 1 km
2016 · npj Quantum Information
Abstract Quantum cryptography allows confidential information to be communicated between two parties, with secrecy guaranteed by the laws of nature alone. However, upholding guaranteed secrecy over networks poses a further challenge, as classical receive-and-resend routing …

Active reset of a radiative cascade for entangled-photon generation beyond the continuous-driving limit
2020 · Physical Review Research
The emission rate of entangled photons from cascaded few-level systems is limited by the dynamics of the radiative transitions. Here, we overcome the continuous driving limit for a semiconductor quantum dot via an active reset …

600 km repeater-like quantum communications with dual-band stabilisation
2020 · arXiv (Cornell University)
Twin-field (TF) quantum key distribution (QKD) fundamentally alters the rate-distance relationship of QKD, offering the scaling of a single-node quantum repeater. Although recent experiments have demonstrated the new opportunities for secure long-distance communications allowed by …

Wavelength-versatile quantum key distribution for reconfigurable classical-quantum networks
2024
We report a high-speed GHz-clocked quantum key distribution (QKD) system, tunable over 65 nm using a novel injection-locked laser design. This paves the way to automatic optimsation of quantum channels in hybrid classical-quantum networks.
