Abstract

We introduce LYNX, a quantum information processor based on trapped 40Ca+ ions. It utilizes up to 31 qubits with all-to-all connectivity. We characterize the system performance using rigorous benchmarks, such as randomized benchmarking (RB), GHZ state fidelity estimates, and quantum volume (QV) tests. The LYNX processor shows average 1-qubit gate errors of 8(5)× 10−5 tested via standard RB in a 24-qubit register. An average 2-qubit gate error in a 24-qubit register of 2.84(8)× 10−3 is demonstrated using interleaved RB. Furthermore, the device passes QV tests using up to 15 qubits which corresponds to a quantum volume of QV=215.

AB  - We introduce LYNX, a quantum information processor based on trapped ^40Ca^+ ions. It utilizes up to 31 qubits with all-to-all connectivity. We characterize the system performance using rigorous benchmarks, such as randomized benchmarking (RB), GHZ state fidelity estimates, and quantum volume (QV) tests. The LYNX processor shows average 1-qubit gate errors of 8(5)× 10^−5 tested via standard RB in a 24-qubit register. An average 2-qubit gate error in a 24-qubit register of 2.84(8)× 10^−3 is demonstrated using interleaved RB. Furthermore, the device passes QV tests using up to 15 qubits which corresponds to a quantum volume of QV=2^15.
