Abstract
An aspect of the disclosure provides an apparatus comprising: an electromagnetic resonator configured to support an oscillating electromagnetic field in a sample; a cold load having a noise temperature lower than the noise temperature of the electromagnetic resonator; a coupler controllable to provide: a first coupling between the electromagnetic resonator and the cold load to reduce the noise temperature of the electromagnetic resonator; a second coupling, different from the first coupling, to the electromagnetic resonator for sensing an electromagnetic field associated with the sample.
