Superconducting Circuits For An A-and-not-b Gate Having An Exclusive-or Gate And An And Gate
Superconducting circuits-based devices and methods for an A-and-not-B gate are provided. In one example, a circuit for an A-and-not-B gate including an output terminal, a first input terminal for receiving a first set of single flux quantum (SFQ) pulses, and a second input terminal for receiving a second set of SFQ pulses is provided. The circuit may further include a first stage configured to perform an exclusive-OR operation on the first set of SFQ pulses received via the first input terminal and the second set of SFQ pulses received via the second input terminal to generate an exclusive-OR result. The circuit may further include a second stage, coupled to the first stage, configured to perform an AND operation on the exclusive-OR result and the first set of SFQ pulses received via the first input terminal and provide an output via the output terminal.
