Abstract
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).
Claims46
A device for storage and/or processing of quantum information, the device comprising:
- a first body, formed from a material having negligible net nuclear or electronic magnetic field;
- a set of data entities embedded in said first body, each data entity of the set of data entities having a plurality of magnetic field states;
- a set of probes, offset from the first body, arranged to acquire internal phase shifts due to magnetic fields of said set of data entities;
- wherein each probe of the set of probes is arranged to move relative to a plurality of data entities of the set of data entities to permit each probe to acquire an internal phase shift from the plurality of data entities;
- and
- a processor arranged to read each probe, establishing a parity of the plurality of data entities while maintaining any superposition of states with that parity.
A method of processing quantum information using a plurality of probes arranged over a plurality of data entities, wherein each data entity of the plurality of data entities has a plurality of magnetic field states, the method comprising:
- moving the plurality probes relative to said plurality of data entities such that each probe of the plurality of probes acquires an internal phase shift from each data entity of a group of data entities of said plurality of data entities in turn;
- and
- measuring a total internal phase shift acquired by each probe, in order to measure a parity for said group of data entities while maintaining any superposition of states with that parity.
A device for storage and/or processing of quantum information, the device comprising:
- a body formed from a material having negligible net nuclear or electronic magnetic field;
- a set of data entities having a plurality of magnetic field states embedded in said body;
- a set of probes also embedded in said body and arranged such that each probe of the set of probes is arranged to acquire an internal phase shift due to a magnetic field of a plurality of data entities of said set of data entities;
- an entity and probe manipulator arranged to apply a set of manipulations to the set of data entities and the set of probes which reduce undesired interactions between the set of data entities and the set of probes;
- and
- a processor arranged to read each probe of the set of probes, establishing a parity of the plurality of data entities of said set of data entities while maintaining any superposition of states with that parity.
