Estimating the term…
A device comprises a first superconducting quantum bit, a second superconducting quantum bit, and a coupler circuit. The first superconducting quantum bit comprises a superconducting tunnel junction and a shunt inductor which form a first superconducting loop. The second superconducting quantum bit comprises a superconducting tunnel junction and a shunt inductor which form a second superconducting loop. The coupler circuit is coupled between the first and second superconducting quantum bits. The coupler circuit is configured to implement an entanglement gate operation between the first and second superconducting quantum bits through exchange interactions between the coupler circuit and the first superconducting quantum bit and the second superconducting quantum bit, when the coupler circuit is driven by a control signal. The coupler circuit is configured to suppress interaction between the first superconducting quantum bit and the second superconducting quantum bit, when the coupler circuit is not driven by the control signal.
A device, comprising:
A system, comprising;
A device comprising a first superconducting fluxonium quantum bit and a second superconducting fluxonium quantum bit coupled by an active coupler circuit which is driven by a control signal to control interaction between the first superconducting fluxonium quantum bit and the second superconducting fluxonium quantum bit.
