  • Methods of constructing and designing RF pulses and exciting or inverting two-level systems
    Patent number: 10956827
    Abstract: The present disclosure provides for a method of designing a radiofrequency or broadband pulse sequence. The method can comprise a qubit (e.g., nuclear spin, photon, electron, atomic spin, dot spin) and a harmonic oscillator wherein a flip angle is controlled by steering a spring between specific states.
    Type: Grant
    Filed: June 14, 2018
    Date of Patent: March 23, 2021
    Assignee: Washington University
    Inventor: Jr-Shin Li
  • Phase-selective entrainment of nonlinear oscillator ensembles
    Patent number: 10693416
    Abstract: A system for entraining an oscillator ensemble is disclosed that includes a plurality of oscillators in an entrained phase pattern. The system includes an entrainment device operatively coupled to each non-linear oscillator of the oscillator ensemble, and the entrainment control device is configured to deliver a 2?-periodic control signal v(?) to all oscillators of the plurality of oscillators to induce the entrained phase pattern.
