Dense Spin Arrays with Low Cross-talk Operations for Quantum Network Applications

Abstract

In this master thesis, we propose a quantum repeater architecture based on a spin array with an efficient optical interface. Single qubit control and multi-qubit gates can be realized by localized electric field with low cross-talk and power consumption. This thesis will also contain how we use electric field to make use of spectral addressing and frequency-multiplexing to increase the quantum repeater performance. We evaluate the performance of the our design in comparison to a routing tree design and show an increased entanglement generation rate scaling into the thousands of qubits regime. Our results enable high fidelity control of dense quantum emitter arrays for scalable networking.
