Success Generating Two-Qutrit Entangling Gates With High Fidelity

Quantum information processors that operate with ternary logic (qutrits) offer significant potential advantages in quantum simulation and error correction, as well as the ability to improve specific quantum algorithms and applications. Building on previous R&D with qutrits at the Advanced Quantum Testbed (AQT), the paper’s experimental team, led by a promising UC Berkeley graduate student, successfully entangled two transmon qutrits with gate fidelities significantly higher than in previously reported works.

A quantum leap in computational performance of quantum processors

A project led by a group of researchers from Israel’s Bar-Ilan University, in collaboration with TII – the Quantum Research Center in Abu Dhabi, United Arab Emirates, is advancing quantum computing by improving the performance of superconducting qubits, the basic computation units of a superconducting quantum processor. The improved qubit, called a tunable superconducting flux qubit, is a micron-sized superconducting loop where electrical current can flow clockwise or counterclockwise, or in a quantum superposition of both directions.
