Abstract Current quantum key distribution (QKD) networks focus almost exclusively on transporting secret keys at the highest possible rate. Consequently, they are built as mostly fixed, ad hoc, logically, and physically isolated infrastructures desig

Quantum key distribution (QKD) allows secret key exchange between two users with unconditional security. For QKD to be widely deployed, low cost and compactness are crucial requirements alongside high performance. Currently, the majority of QKD syste

Abstract Measurement-device-independent quantum key distribution (MDI-QKD) is a technique for quantum-secured communication that eliminates all detector side-channels, although is currently limited by implementation complexity and low secure key rate

Quantum light sources operating at telecom wavelength are a long-sought goal for quantum technologies. Here, the authors show electrically injected emission of single photons and entangled photon pairs from indium phosphide based quantum dots, operat

Measurement-device-independent quantum digital signatures would allow a document to be signed and transferred with information-theoretic security. Here, the authors reach this goal using a reconfigurable quantum network where the central node can swi

Abstract Quantum key distribution’s (QKD’s) central and unique claim is information theoretic security. However there is an increasing understanding that the security of a QKD system relies not only on theoretical security proofs, but also on how

Photonic time-bin qubits are well suited to transmission via optical fibers and waveguide circuits. The states take the form 1/sqrt[(2)](α|0⟩+e^{iϕ}β|1⟩), with |0⟩ and |1⟩ referring to the early and late time bin, respectively. By controll

The art of imparting information onto a light wave by optical signal modulation is fundamental to all forms of optical communication. Among many schemes, direct modulation of laser diodes stands out as a simple, robust, and cost-effective method. How

In the quantum version of a Trojan-horse attack, photons are injected into the optical modules of a quantum key distribution system in an attempt to read information direct from the encoding devices. To stop the Trojan photons, the use of passive opt
