Literature review on: Quantum readout of spin resonance in a silicon transistor

Abstract

Phosphorus donor spins in silicon are promising quantum bit (qubit) candidates. They have a natural confinement potential, long spin lifetimes and decades of use in the semiconductor fabrication industry. Readout of a single qubit is a necessary step to build a quantum computer, which could potentially solve particular problems exponentially faster than conventional computers. Electrically detected magnetic resonance has previously been used to measure the spin state of an ensemble of spins. In this literature review, the concept of a quantum computer is introduced before the potential of using electrically detected magnetic resonance to measure the spin state of a single donor spin qubit in a silicon transistor is discussed.
