Abstract: 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.

Abstract: A method for operating a superconducting device (1; 1a, 1b), having a coated conductor (2) with a substrate (3) and a quenchable superconducting film (4), wherein the coated conductor (2) has a width W and a length L, is characterized in that 0.5≦L/W≦10, in particular 0.5≦L/W≦8, and that the coated conductor (2) has an engineering resistivity ρeng shunting the superconducting film (4) in a quenched state, with ρeng>2.5 Ω, wherein RIntShunt=ρeng*L/W, with RIntShunt: internal shunt resistance of the coated conductor (2). The risk of a burnout of a superconducting device in case of a quench in its superconducting film is thereby further reduced to such an extent that the device can be operated without use of an additional external shunt.

Abstract: A fiber optical superconducting nanowire detector with increased detector efficiency, fabricated directly on the tip of the input optical fiber. The fabrication on the tip of the fiber allows precise alignment of the detector to the fiber core, where the field mode is maximal. This construction maximizes the coupling efficiency to close to unity, without the need for complex alignment procedures, such as the need to align the input fiber with a previously fabricated device. The device includes a high-Q optical cavity, such that any photon entering the device will be reflected to and fro within the cavity numerous times, thereby increasing its chances of absorption by the nanowire structure. This is achieved by using dedicated cavity mirrors with very high reflectivity, with the meander nanowire structure contained within the cavity between the end mirrors, such that photons impinge on the nanowire structure with every traverse of the cavity.

Abstract: Provided is a fault current limiter that uses a superconductor and can rapidly restore a superconducting state after a current limiting operation. The fault current limiter is configured to perform a current limiting operation through the use of a superconductor and includes a superconducting member (a member including a holding container, a filler and a superconducting wire) including the superconductor, a cooling container, and a suppression member (fins). The cooling container is configured to hold therein the superconducting member and house therein a coolant for cooling the superconducting member. The suppression member (fins) is configured to prevent a boiling state of the coolant from transiting from a nucleate boiling state to a film boiling state in the case where the coolant boils on a surface of the superconducting member (a surface of the holding container) due to a temperature rise of the superconductor during the current limiting operation.
