Superconducting weak link array switch |
摘要 |
The present invention provides a superconducting switch which has a substrate base and a control line patterned thereon. A buffer layer is deposited on top of these and then a superconducting material is deposited and then patterned wherein the superconducting material forms a strip having multiple intersections with the control line. At each intersection between the control line and the superconducting strip is formed a superconducting gate due to the double step edge junction. The control line underneath provides (1) a means for constructing step edge weak link junctions; (2) a means for heating the weak link junctions; and (3) generating an electromagnetic field near the weak link junctions. In combination, a very small magnetic field can be used to decrease the critical current to a very low level.
