Patent attributes
The various embodiments described herein include methods, devices, and systems for implementing logic gates. In one aspect, a circuit includes: (1) superconducting components; (2) heat sources, each coupled to a corresponding superconducting component and configured to selectively provide heat to that component; and (3) a current source coupled to the superconducting components and configured to selectively provide: (a) a first current to bias the components such that combination of the first current and heat from any heat source causes the components to transition to a non-superconducting state; and (b) a second current to bias the components such that (i) combination of the second current and heat from each heat source causes the components to transition to the non-superconducting state, and (ii) a combination of the second current and heat from only a subset of the heat sources does not cause the components to transition to the non-superconducting state.
