  • Robust quantum logical gates
    Patent number: 11451231
    Abstract: Techniques for implementing robust quantum logic gates are provided and described. In some aspects, a quantum logic gate between a plurality of cavities comprising a first cavity and a second cavity is implemented by performing a first beam splitter operation between the first cavity and the second cavity using a coupling transmon that is dispersively coupled to both the first cavity and the second cavity, and performing a controlled phase shift operation between the second cavity and an ancilla transmon that is dispersively coupled to the second cavity but not dispersively coupled to the first cavity.
    Type: Grant
    Filed: January 5, 2019
    Date of Patent: September 20, 2022
    Assignee: Yale University
    Inventors: Liang Jiang, Steven M. Girvin, Brian Lester, Yvonne Gao, Robert J. Schoelkopf, III
  • Techniques for manipulation of two-qubit quantum states and related systems and methods
    Patent number: 11184006
    Abstract: According to some aspects, a method is provided of operating a system that includes a multi-level quantum system dispersively coupled to a first quantum mechanical oscillator and dispersively coupled to a second quantum mechanical oscillator, the method comprising applying a first drive waveform to the multi-level quantum system, applying one or more second drive waveforms to the first quantum mechanical oscillator, and applying one or more third drive waveforms to the second quantum mechanical oscillator.
