High-rate quantum cryptography in untrusted networks
Stefano Pirandola, Carlo Ottaviani, Gaetana Spedalieri +6
We extend the field of continuous-variable quantum cryptography to a network formulation where two honest parties connect to an untrusted relay by insecure quantum links. To genera…
How Discord underlies the Noise Resilience of Quantum Illumination
Christian Weedbrook, Stefano Pirandola, Jayne Thompson +2
The benefits of entanglement can outlast entanglement itself. In quantum illumination, entanglement is employed to better detect reflecting objects in environments so noisy that al…
Two-way quantum cryptography at different wavelengths
Christian Weedbrook, Carlo Ottaviani, Stefano Pirandola
We study the security of two-way quantum cryptography at different wavelengths of the electromagnetic spectrum, from the optical range down to the microwave range. In particular, w…
Continuous-variable dense coding by optomechanical cavities
Shabir Barzanjeh, Stefano Pirandola, Christian Weedbrook
In this paper, we show how continuous-variable dense coding can be implemented using entangled light generated from a membrane-in-the-middle geometry. The mechanical resonator is a…
Improvement of two-way continuous-variable quantum key distribution using optical amplifiers
Yi-Chen Zhang, Zhengyu Li, Christian Weedbrook +5
The imperfections of a receiver's detector affect the performance of two-way continuous-variable quantum key distribution protocols and are difficult to adjust in practical situati…
Quantum secret sharing with continuous-variable cluster states
Hoi-Kwan Lau, Christian Weedbrook
We extend the formalism of cluster state quantum secret sharing, as presented in Markham and Sanders [Phys. Rev. A 78, 042309 (2008)] and Keet et al. [Phy. Rev. A 82, 062315 (2010)…
