Titre | Scaling-up the phosphorus-in-silicon quantum processor |
Résumé | Quantum computers will allow specific algorithms to be performed with unprecedented efficiency and push ahead the frontiers of knowledge. Donor spin qubits in silicon are an ideal platform for that: they can be fabricated with standard semiconductor processes, are controlled with error rates as small as 10-4 and maintain their quantum coherence for almost a minute [1]. However, multi-qubit operations and long-distance donor coupling remain a formidable challenge. Here we present a scalable design for a silicon quantum processor [2] that is compatible with current fabrication capabilities. Quantum information is encoded in the electron-nuclear spin states, while long-distance high-fidelity interactions can be achieved either via direct electric dipole interactions or via photonic links. Prototypical devices are fabricated to demonstrate the processors basic units. [1] J. T. Muhonen, et.al. Nature Nanotechnol. 9, 986 (2014). [2] G. Tosi, et.al. arXiv:1509.08538 (2015) |
