Whole?Device Entanglement in a 65?Qubit Superconducting Quantum Computer

The ability to generate large-scale entanglement is an important progenitor of quantum information processing capability in noisy intermediate-scale (NISQ) devices. In this paper, we investigate the extent which entangled states over large numbers qubits can be prepared on current superconducting We native-graph IBM Quantum 65-qubit $\textit{ibmq_manhattan}$ device and 53-qubit $\textit{ibmq_rochester}$ applied readout-error mitigation (QREM). Connected graphs spanning each full devices were detected, indicating bipartite whole device. application QREM was shown increase observed within all measurements, particular, detected number pairs found increased from 31 56 total 58 connected pairs. results work indicate two largest date.
