Quantum Computing using Electron Spin in Group IV Semiconductors

Professor Eli Yablonovitch

UCLA

Abstract

This talk will present a systems analysis for a Quantum Factorization Engine built in Si-Ge technology. This will be a review of the types of devices and system architectures that will be needed in order to make a quantum information processor in the Ge-Si material system. Attention will be paid to the required elementary operations; single spin measurement, single spin rotation, and two spin interaction. The UCLA group has recently measured a single electron spin inside a conventional Silicon integrated circuit. The fidelity requirement of the gate operations for quantum error correction represents the principal technical challenge, among many others.
