Methods and controllers for reading a quantum state of an atomic object and/or qubit using coherent shelving are provided. A controller causes a first beam of a first wavelength and a second beam of a second wavelength to be incident on the qubit and causes a reading beam to be incident on the qubit. The first wavelength and the second wavelength are configured to couple a state of a qubit space of the qubit to a stable state. The stable state has a lifetime that is longer than a length of time required for performing a reading operation. The first beam and the second beam are generated by at least one manipulation source operated by at least one manipulation source driver of and/or in communication with and/or controlled by the controller.
