We propose non-latching gates based on Superconducting QUantum Interference Device (SQUID) and logic circuits based on it. The gate consists of a 3-junction-SQUID coupled with an RF-SQUID inductively.

All-optical NOT logic gate is theoretically described using the concept of polarization-conversion in ring resonator. Conversion of polarization states occurs at very high speed of 0.2 ps and high ...
