Abstract
A quantum magnetometer for measuring a magnetic field is provided. A Pauli Spin Blockade (PSB) system having, the at least discrete physical feature with a given spin state tunnel coupled to each of a source and a drain, is provided. The at least discrete physical feature is positioned between the source and the drain. A detector is configured to detect a magnetic field-dependent spin state at one or more of the source lead or the drain lead. An amplifier is configured to amplify the detected magnetic field-dependent transport current in some inventive embodiments.
