Logical multi-qubit entanglement with dual-rail superconducting qubits
Wenhui Huang, Xuandong Sun, Jiawei Zhang +21
Recent advances in quantum error correction (QEC) across hardware platforms have demonstrated operation near and beyond the fault-tolerance threshold, yet achieving exponential sup…
Logical operations with a dynamical qubit in Floquet-Bacon-Shor code
Xuandong Sun, Longcheng Li, Zhiyi Wu +29
Quantum error correction (QEC) protects quantum systems against inevitable noises and control inaccuracies, providing a pathway towards fault-tolerant (FT) quantum computation. Sta…
A C-Band Cryogenic GaAs MMIC Low-Noise Amplifier for Quantum Applications
Zechen Guo, Daxiong Sun, Peisheng Huang +16
Large-scale superconducting quantum computers require massive numbers of high-performance cryogenic low-noise amplifiers (cryo-LNA) for qubit readout. Here we present a C-Band mono…
