Final Report: Ultrapure Reactive Ion Etching for Scalable Nanofabrication of Carbon-Based Semiconductor Quantum Devices

Abstract

Quantum information science requires networks of entangled quantum bits (qubits) on which single and multi-qubit logic operations can be performed. Thanks to rapid progress over recent years, color centers in diamond have emerged as one of the leading contenders for scalable and reliable qubits. The diamond nitrogen vacancy (NV) center has spin coherence times in excess of one second, and the spin state can be optically initialized, manipulated, and measured. Quantum network protocols based on these unique qualities have been proposed, two-node quantum networks have been implemented over more than 1 km (by far the longest distance for all matter qubits), and full quantum error correction has been demonstrated including non-destructive measurements and real-time feedback.
