Limitations of Error Model Approximations in Quantum Network Simulation

Julia Freund, Jorge Miguel-Ramiro, Julius Wallnöfer +1

Efficient classical simulation of large-scale quantum networks frequently relies on noise approximations, which consider a restricted set of operators to describe noisy channels an…

Merging-Based Quantum Repeater

Maria Flors Mor-Ruiz, Jorge Miguel-Ramiro, Julius Wallnöfer +2

We introduce an alternative approach for the design of quantum repeaters based on generating entangled states of growing size. The scheme utilizes quantum merging operations, also…
