Kinematic Emergence of the Page Curve in a Local Transverse-Field Ising Model
Samuel J. W. Jones, M. Basil Altaie, Benjamin T. H. Varcoe
We present a controllable quantum spin-chain model that reproduces the Page curve (the rise-and-fall of bipartite entanglement expected in black-hole evaporation), using only local…

The Manipulate-and-Observe Attack on Quantum Key Distribution
William Tighe, George Brumpton, Mark Carney +1
Quantum key distribution is often regarded as an unconditionally secure method to exchange a secret key by harnessing fundamental aspects of quantum mechanics. Despite the robustne…
