US Patent 12095462 Superconducting logic circuits

An electric circuit includes one or more photon detector components and a superconducting logic gate component coupled to respective outputs of the one or more photon detector components. The electric circuit further includes a bias source electrically coupled to the superconducting logic gate component, the bias source configured to provide a bias current adapted to cause the superconducting logic gate component to function as a logical gate. The electric circuit also includes an optical switch component electrically coupled to an output of the superconducting logic gate component.
