A magnetic field causing a difference of energy level between different spin states in the sample can be applied, a spin transition in the material can be triggered by exposing the sample to electromagnetic radiation of an energy level corresponding to the difference in energy level between the different spin states, a sensing surface of a superconducting element can be exposed to a magnetic field of the spins in the sample, the spin transition can cause, via kinetic inductance, a change in electromagnetic waves carried by the superconducting element which can be detected. A magnetic field component normal to the sensing surface, below a certain magnetic field threshold, can be applied to favor sensitivity.

System and method for sensing spin

A quantum dot structure having a split-gate geometry is provided. The quantum dot is configured for incorporation into a quantum dot array of a quantum processing unit. A gap between a reservoir accumulation gate and a quantum dot accumulation gate provides a tunnel barrier between an electric charge reservoir and a quantum dot well. An electrical potential applied to the gates defines a tunnel barrier height, width and charge tunneling rate between the well and the reservoir without relying on any barrier gate to control the charge tunneling rate.
