Pulse-engineered Controlled-V gate andits applications on superconductingquantum device

In this article, we demonstrate that, by employing the OpenPulse design kit for IBM superconducting quantum devices, controlled-V gate ( cv gate) can be implemented in about half time to controlled-X xmlns:xlink="http://www.w3.org/1999/xlink">cx or xmlns:xlink="http://www.w3.org/1999/xlink">cnot and consequently 65.5% reduced compared -based implementation of . Then, based on theory Cartan decomposition, characterize set all two-qubit gates with only two three gates; using pulse-engineered gates, enables us implement these shorter possibly better fidelity than one, as actually demonstrated examples. Moreover, showcase improvement linearly coupled three-qubit Toffoli implementing it gate, both averaged output-state fidelity. These results imply importance our technique, which, an additional option basis design, may shorten overall computation improve precision several algorithms executed a real device.
