Control of single spin in CMOS devices and its application for quantum bits.
Résumé
We show how to measure and manipulate a single spin in a CMOS device fabricated in a preindustrial 300 nm CMOS foundry. The device can be used as a spin quantum bit working at very low temperature. The spin manipulation is done by a microwave electric field applied directly on a gate. The presented results are a proof-of-principle demonstration of the possibility to define qubits by means of conventional industrial fabrication processes.
