Abstract
Embodiments of quantum clocks for a master/slave architecture are generally described herein. In some embodiments, a coupled pair of entangled particles is generated using a particle source. A first of the entangled particles of the coupled pair is used as a master clock. A second of the entangled particles of the coupled pair is used as a slave clock. Quantum states of the first entangled particle of the coupled pair associated with the master clock and the second of the entangled particles of the coupled pair associated with the slave clock are entangled by an Einstein-Podolsky-Rosen (EPR) link.

A method for providing quantum clocks, comprising:
- generating a coupled pair of entangled particles using a particle source;
- using a first of the entangled particles of the coupled pair as a master clock, wherein the master clock comprises a locally generated pausable clock that, when paused, enables data latching by a port latch;
- and
- using a second of the entangled particles of the coupled pair as a slave clock;
- wherein quantum states of the first entangled particle of the coupled pair associated with the master clock and the second of the entangled particles of the coupled pair associated with the slave clock are entangled by an Einstein-Podolsky-Rosen (EPR) link.
A quantum clocking system, comprising:
- an entangled particle source arranged to generate a first coupled pair of entangled particles;
- a master clock arranged to provide a master clock using a first of the entangled particles of the first coupled pair, wherein the master clock comprises a locally generated pausable clock that, when paused, enables data latching by a port latch;
- and
- a slave clock arranged to provide a slave clock using a second of the entangled particles of the first coupled pair;
- and
- an Einstein-Podolsky-Rosen (EPR) link for synchronizing the master clock and the slave clock via entanglement of quantum states of the first entangled particle of the first coupled pair associated with the master clock and the second of the entangled particles of the first coupled pair associated with the slave clock.
A system on a chip, comprising:
- a quantum clock module arranged to provide a master clock, the quantum clock further comprising a local oscillator pump laser for generating a laser beam having a plurality of photons, a spontaneous parametric down converter, the laser beam being passed through the spontaneous parametric down converter to produce a coupled pair of entangled photons, wherein the master clock is provided using a first of the coupled pair of entangled photons, wherein the master clock comprises a locally generated pausable clock that, when paused, enables data latching by a port latch;
- at least one node arranged to provide a first functionality, the at least one node implemented using at least one slave clock, the at least one slave clock implemented using a second of the coupled pair of entangled photons;
- and
- an Einstein-Podolsky-Rosen (EPR) link for synchronizing the master clock and the at least one slave clock via entanglement of quantum states of the first of the coupled pair of entangled photons associated with the master clock and the second of the entangled photons associated with the at least one slave clock.
