Berkeley Lab Team Demonstrates a Three-Qubit Native Quantum Gate With High Fidelity

…Researchers at the Advanced Quantum Testbed (AQT) at Lawrence Berkeley National Laboratory (Berkeley Lab) conducted the first experimental demonstration of a three-qubit high-fidelity iToffoli native gate in a superconducting quantum information processor and in a single step…

…Noisy intermediate-scale quantum processors typically support one- or two-qubit native gates, the types of gates that can be implemented directly by hardware…

…The team’s demonstration adds a novel and robust native three-qubit iToffoli gate for universal quantum computing…at a very high fidelity operation of the gate at 98.26%…
