  • Connecting Electrical Circuitry in a Quantum Computing System
    Publication number: 20230067066
    Abstract: In some aspects, a flexible cable may comprise: a flexible strip with first and second parallel surfaces and first and second ends, said flexible strip being electrically insulating; a metal stripline within said flexible strip; first and second metallic grounding planes on said first and second surfaces, respectively; and a first circuit board mechanically attached to at least one of said first end of said flexible strip and said first and second metallic grounding planes at said first end, said first circuit board being mechanically stiff, said metal stripline being electrically connected to electrical circuitry on said first circuit board.

  • Heat switches for controlling a flow of heat between thermal stages of a cryostat
    Patent number: 11287171
    Abstract: Heat switches are presented herein for controlling a flow of heat between thermal stages of a cryostat. In one aspect, a heat switch for a cryostat includes a thermal linkage configured to simultaneously contact a first thermal stage and a second thermal stage of the cryostat and define a thermal pathway therebetween. The thermal linkage includes a superconducting element disposed along a portion of the thermal pathway that is capable of transitioning between a superconducting state and a non-superconducting state. A thermal conductivity of the superconducting state is lower than a thermal conductivity of the non-superconducting state. Other types of heat switches are presented, including methods for controlling a flow of heat between thermal stages of a cryostat.
