Scalable Low-overhead Superconducting Non-local Coupler with Exponentially Enhanced Connectivity
Haonan Xiong, Jiahui Wang, Juan Song +8
Quantum error correction codes with non-local connections such as quantum low-density parity-check (qLDPC) incur lower overhead and outperform surface codes on large-scale devices.…

A cryogenic on-chip microwave pulse generator for large-scale superconducting quantum computing
Zenghui Bao, Yan Li, Zhiling Wang +7
For superconducting quantum processors, microwave signals are delivered to each qubit from room-temperature electronics to the cryogenic environment through coaxial cables. Limited…

An ultra-high gain single-photon transistor in the microwave regime
Zhiling Wang, Zenghui Bao, Yan Li +9
A photonic transistor that can switch or amplify an optical signal with a single gate photon requires strong non-linear interaction at the single-photon level. Circuit quantum elec…
