Continuous-variable quantum digital signatures over insecure channels

Matthew Thornton, Hannah Scott, Callum Croal +1

Digital signatures ensure the integrity of a classical message and the authenticity of its sender. Despite their far-reaching use in modern communication, currently used signature…

Optimizing the spectro-temporal properties of photon pairs from Bragg-reflection waveguides

H. Chen, K. Laiho, B. Pressl +6

Bragg-reflection waveguides (BRWs) fabricated from AlGaAs provide an interesting non-linear optical platform for photon-pair generation via parametric down-conversion (PDC). In con…

Time-dependent resonance interaction energy between two entangled atoms under non-equilibrium conditions

Giuseppe Fiscelli, Roberta Palacino, Roberto Passante +3

We consider the time-dependent resonance interaction energy between two identical atoms, one in the ground state and the other in an excited state, and interacting with the vacuum…

Introduction to the Dicke model: from equilibrium to nonequilibrium, and vice versa

Peter Kirton, Mor M. Roses, Jonathan Keeling +1

The Dicke model describes the coupling between a quantized cavity field and a large ensemble of two-level atoms. When the number of atoms tends to infinity, this model can undergo…

High-concurrence time-bin entangled photon pairs from optimized Bragg-reflection waveguides

Huan Chen, Silke Auchter, Maximilian Prilmüller +9

Semiconductor Bragg-reflection waveguides are well-established sources of correlated photon pairs as well as promising candidates for building up integrated quantum optics devices.…

Toward Scalable Boson Sampling with Photon Loss

Hui Wang, Wei Li, Xiao Jiang +16

Boson sampling is a well-defined task that is strongly believed to be intractable for classical computers, but can be efficiently solved by a specific quantum simulator. However, a…
