Abstract

Solid control A Swiss–US collaboration demonstrates that quantum optical techniques, conventionally used for cooling, measurement and control of isolated atoms and ions, can be applied to control the quantum dynamics of the many-body environment of solid-state qubits — an important goal in quantum science and engineering. Specifically, all-optical manipulation of the electronic spin of an individual nitrogen-vacancy colour centre in diamond (involving dark-resonances and coherent population trapping) was used to produce optical cooling, real-time projective measurement and control of surrounding nuclear spin ensembles. Potential applications range from all-optical nanomagnetometry to quantum feedback control of solid-state qubits.
