Silicon in the Quantum Limit: Quantum Computing and Decoherence in Silicon Architectures

Understand

Semiconductor architectures hold promise for quantum information processing (QIP) applications due to their large industrial base and perceived scalability potential.

• Electron spins in silicon in particular may be an excellent architecture for QIP and also for spin electronics (spintronics) applications.
• While the charge of an electron is easily manipulated by charged gates, the spin degree of freedom is well isolated from charge fluctuations.
• Inherently small spin-orbit coupling and the existence of a spin-zero Si isotope facilitate long single spin qubit coherence times.
