A device for the storage and/or processing of quantum information comprises: a body ( 6 ), formed from a material having negligible net nuclear or electronic magnetic field; a set of data entities ( 4 ) embedded in said body, each having a plurality of magnetic field states; a set of probes ( 2 ), offset from the body, arranged to acquire internal phase shifts due to the magnetic fields of said data entities; wherein the probes ( 2 ) are each arranged to move relative to a plurality of data entities ( 4 ) in order that each probe ( 2 ) acquires an internal phase shift from the plurality of data entities ( 4 ); and means for reading each probe ( 2 ), thereby establishing a parity of the plurality of data entities ( 4 ). |
