Publication number: 20230419157Abstract: A fault-tolerant quantum computing scheme implements quantum computing based on three-dimensional cluster states using just a small number of physical components. The technique may be implemented using a single actively controlled qubit [100], e.g., a quantum emitter, and a pair of delay line loops [106, 108], which can be physically realized using existing technologies in quantum photonic and phononic systems. A three-dimensional cluster state is prepared by using the actively con-trolled qubit to generate data qubits that propagate through the two delay line loops, interact with the actively controlled qubit, and then are measured by a detector [110].Type: ApplicationFiled: November 9, 2021Publication date: December 28, 2023Applicant: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Kianna Wan, Soonwon Choi, Isaac H.

Patent number: 11360174Abstract: Systems and methods are disclosed for a pulse sequence that reduces disorder and/or interaction effects in spin systems. A protocol can be used to design a pulse sequence that includes altering the frame orientation of the spin system with each electromagnetic pulse in the pulse sequence. The frame orientations during the sequence can conform to certain conditions. The number positive rotations along each axis can be the same as the number negative rotations along the respective axis. The number of rotations along one axis should be the same as the number of rotations along the other axes.Type: GrantFiled: March 6, 2020Date of Patent: June 14, 2022Assignee: President and Fellows of Harvard CollegeInventors: Mikhail D.

Patent number: 10712406Abstract: A method for quantum metrology using stable non-equilibrium states of quantum matter, such as many-body quantum spin systems, is disclosed. The approach can utilize quantum correlations in such many-body quantum spin systems stabilized by strong interactions and periodic driving for reduction of noise. As an example, an exemplary protocol to perform Floquet enhanced measurements of an oscillating magnetic field in Ising-interacting spin systems is provided. These approaches allow for circumvention of the interaction-induced decoherence associated with high density spin ensembles and is robust to the presence of noise and imperfections. The protocol is applicable to nanoscale magnetic sensing and other precision measurements.Type: GrantFiled: December 28, 2018Date of Patent: July 14, 2020Assignees: President and Fellows of Harvard College, The Regents of The University of CaliforniaInventors: Mikhail D.
