Hierarchical Logical Processor on the Rotated Surface Code with Shuttle Buses
Zi-Han Chen, Ming-Cheng Chen, Chao-Yang Lu +1
Quantum platforms with beyond-planar connectivity provide new opportunities for fault-tolerant quantum computation (FTQC). While quantum low-density parity-check (qLDPC) codes offe…
Taming Rydberg Decay with Measurement-based Quantum Computation
Cheng-Cheng Yu, Zi-Han Chen, Yu-Hao Deng +3
Programmable neutral atom arrays show great promise for fault-tolerant quantum computing. A dominant physical error on this platform is qubit leakage and loss, notably decay errors…
Locating Rydberg Decay Error in SWAP-Leakage Reduction Circuit Protocol
Cheng-Cheng Yu, Yu-Hao Deng, Ming-Cheng Chen +2
Qubit leakage and loss, particularly Rydberg-induced decay during two-qubit gates, pose significant challenges to fault-tolerant quantum computing with neutral atom arrays, as they…
High-Performance Quantum Frequency Conversion from Ultraviolet to Telecom Band
Yi Yang, Bin Wang, Ji-Chao Lin +10
Quantum frequency conversion (QFC) is essential for bridging the spectral gap between stationary qubits and low-loss optical communication channels. In this work, we demonstrate a…
Sustaining high-fidelity quantum logic in neutral-atom circuits via mid-circuit operations
Rui Lin, You Li, Le-Tian Zheng +11
The realization of fault-tolerant quantum computation hinges on the ability to execute deep quantum circuits while maintaining gate fidelities consistently above error-correction t…
Directly observing relativistic Bohmian mechanics
Yun-Fei Wang, Hui Wang, Tong Zhang +4
Bohmian mechanics, also referred to as the de Broglie-Bohm pilot-wave theory, represents a deterministic and nonlocal interpretation of quantum mechanics. Since its origination in…
