Novel Two-qubit Gate Through Raman-type Transition

ORAL

Abstract

Two-qubit gates are essential for quantum computing. Presently, the low fidelity of these operations is a major factor limiting the physical implementation of long quantum algorithms. In this talk, we propose an entangling gate for directly coupled superconducting qubits based on a Raman-type transition and numerically show that it is fast and high fidelity. This gate is all-microwave and does not require additional hardware compared to standard cQED experiments.
