  • Patent number: 12039406
    Abstract: An apparatus useful for creating and measuring states of an entangled system, comprising a pair of interacting multi-level systems, each of systems comprising a state |g>, a state |r>, and state |r*>. One or more first electromagnetic fields excite a first transition between the ground state |g> and the state |r> to create an entangled system. One or more second electromagnetic fields are tuned between the state |r> and the intermediate state |r*> so that any population of the systems in |r*> are dark to a subsequent detection of a population in the systems in |g>, providing a means to distinguish the entangled system in the state |g> and the entangled system in the state |r>. In one or more examples, the systems comprise neutral Rydberg atoms.

  • Publication number: 20240184845
    Abstract: A computer-implemented method of solving a reconfiguration problem, the method comprising: solving an all-pairs shortest path (APSP) problem, including computing a distance between each token source location and each token target location; solving an assignment problem on the computed distances, said solving the assignment problem yielding a path system having a set of shortest paths; performing a cycle breaking function on the path system, the cycle-breaking function breaking all cycles in the path system; and ordering order the cycle free path system.

  • Patent number: 9664767
    Abstract: A system for performing Walsh reconstruction of time dependent fields with a quantum probe that includes a diamond structure that includes nitrogen-vacancy (NV) centers for sensing magnetic and electric fields. An arbitrary waveform generator and microwave waveguides manipulate the quantum spins in the diamond structure using a plurality of coherent control sequences to measure the arbitrary profile of time-varying magnetic fields.
