Abstract: The various embodiments described herein include methods, devices, and systems for fabricating and operating photodetector circuitry. In one aspect, a photon detector system includes: (1) a first superconducting wire having a first threshold superconducting current; (2) a second superconducting wire having a second threshold superconducting current; (3) a resistor coupled to the first wire and the second wire; (4) current source(s) coupled to the first wire and configured to supply a current that is below the second threshold current; and (3) a second circuit coupled to the second wire. In response to receiving light at the first wire, the first wire transitions from a superconducting state to a non-superconducting state. In response to receiving light at the second wire while the first wire is in the non-superconducting state, the second wire transitions to a non-superconducting state, redirecting the first current to the second circuit.

Abstract: A method includes receiving input light having an input wavelength in a first optical resonator for causing resonance of the input light in the first optical resonator. The first optical resonator includes a non-linear optical medium. The method also includes converting at least a portion of the input light to a combination of first output light having a first output wavelength that is different from the input wavelength and second output light having a second output wavelength that is different from the input wavelength and the first output wavelength by passing the input light through the non-linear optical medium. The method further includes causing resonance of the first output light and the second output light in a second optical resonator. A portion of the first optical resonator is coupled to a portion of the second optical resonator.

Abstract: The various embodiments described herein include methods, devices, and systems for fabricating and operating superconducting circuitry. In one aspect, an electronic system includes: (1) a first circuit that includes a plurality of superconducting wires connected in parallel with one another, the plurality of superconducting wires including: (a) a first superconducting wire with a corresponding first threshold superconducting current; and (b) a second superconducting wire; (2) a second circuit connected in parallel to the first circuit; (3) a first current source coupled to the first superconducting wire and configured to selectively supply a first current; and (4) a second current source coupled to a combination of the first circuit and the second circuit and configured to supply a second current such that the plurality of superconducting wires operate in a superconducting state; where a combination of the first current and the second current exceeds the first threshold superconducting current.
