Abstract
An apparatus comprising: a crystal; and a colour centre located within the crystal and adapted to receive: a magnetic field, such that a projection of the magnetic field onto a colour centre axis of the colour centre causes a change in an electron spin resonance frequency of the colour centre, and an electromagnetic signal having a frequency that substantially matches the electron spin resonance frequency of the colour centre as changed by the projection of the magnetic field onto the colour centre axis.

An apparatus comprising:
- a crystal;
- and
- a colour centre located within the crystal and adapted to receive:
- a magnetic field, such that a projection of the magnetic field onto a colour centre axis of the colour centre causes a change in an electron spin resonance frequency of the colour centre, and
- an electromagnetic signal having a frequency that substantially matches the electron spin resonance frequency of the colour centre as changed by the projection of the magnetic field onto the colour centre axis.
A quantum system comprising:
- a crystal;
- and
- a colour centre located within the crystal;
- a magnetic field generator;
- an electromagnetic signal generator;
- a memory embodying computer-readable instructions;
- and
- a processor coupled to the magnetic field generator, the electromagnetic signal generator and the memory, wherein the processor is configured to execute the computer-readable instructions, which are configured, upon execution by the processor, to cause the processor to:
- control the magnetic field generator to generate a magnetic field such that a projection of the magnetic field onto a colour centre axis of the colour centre causes a change in an electron spin resonance frequency of the colour centre, and
- control the electromagnetic signal generator to generate an electromagnetic signal having a frequency that substantially matches the electron spin resonance frequency of the colour centre as changed by the projection of the magnetic field onto the colour centre axis.
A method of addressing a colour centre in a crystal, the method comprising:
- generating a magnetic field, such that a projection of the magnetic field onto a colour centre axis of the colour centre causes a change in an electron spin resonance frequency of the colour centre;
- and
- generating an electromagnetic signal having a frequency that substantially matches the electron spin resonance frequency of the colour centre as changed by the projection of the magnetic field onto the colour centre axis.
