Building High Bandwidth Quantum Repeaters using Quantum Error Correction
Quantum networks, with applications ranging from quantum key distribution to distributed quantum computing, ultimately require the sharing of entangled bell pairs between distant parties. The rate at which these pairs need to be generated depends on the application, but can approach and even exceed rates of one giga-entangled bit per second. To reach such rates at large separation distances, devices called quantum repeaters must be used to overcome photonic qubit errors and loss. In this talk, I will briefly discuss the different generations of proposed quantum repeaters and the application of quantum error correction within these devices. I will then analyze the performance that can be expected for these devices given both current quantum logic gate speed and fidelities and using optimal configurations, as well as what can be expected when the error rates of these devices improve.
