Abstract
A quantum device with a tunable resonant frequency including a ferromagnetic link including a ferromagnetic material and a first superconducting layer and a second superconducting layer coupled to each other by the ferromagnetic link, the ferromagnetic link being configured in a magnetization configuration arranged in a first arrangement corresponding to a first resonant frequency of the quantum device or in a second arrangement corresponding to a second resonant frequency of the quantum device.
Claims20
A quantum device with a tunable resonant frequency, the quantum device comprising:
- a ferromagnetic link comprising a ferromagnetic material;
- and
- a first superconducting layer and a second superconducting layer coupled to each other by the ferromagnetic link,
- wherein the ferromagnetic link is configured in a magnetization configuration arranged in a first arrangement corresponding to a first resonant frequency of the quantum device or in a second arrangement corresponding to a second resonant frequency of the quantum device.
An method of controlling a cubit coupler, the method comprising:
- coupling cubits by applying a first external signal to the cubit coupler to allow a magnetization configuration of a ferromagnetic link, the ferromagnetic link being configured to couple a first superconducting layer and a second superconducting layer of the cubit coupler, to be arranged in a first arrangement to configure the cubit coupler to have a first resonant frequency;
- and
- decoupling the cubits by applying a second external signal to the cubit coupler to allow the magnetization configuration of the ferromagnetic link to be arranged in a second arrangement to configure the cubit coupler to have a second resonant frequency.
