Hierarchical Quantum Logical Processor with Amortized Long-Range Connectivity
Zi-Han Chen, Ming-Cheng Chen, Chao-Yang Lu +1
High qubit overhead is a key bottleneck for fault-tolerant quantum computation. Quantum low-density parity-check (qLDPC) codes offer high encoding efficiency but typically require…
Squeezed-slit Bohr-Einstein Interferometer
Hao-Wen Cheng, Xu-Zhao-Qiu Zeng, Yu-Chen Zhang +9
The Einstein-Bohr recoiling-slit gedankenexperiment, a cornerstone of quantum complementarity, has long been constrained by the zero-point fluctuations of the atomic slit -- the sp…
Efficient Magic State Cultivation on
Zi-Han Chen, Ming-Cheng Chen, Chao-Yang Lu +1
Preparing high-fidelity logical magic states is crucial for fault-tolerant quantum computation. Among prior attempts to reduce the substantial cost of magic state preparation, magi…
Transversal Logical Clifford gates on rotated surface codes with reconfigurable neutral atom arrays
Zi-Han Chen, Ming-Cheng Chen, Chao-Yang Lu +1
We propose hardware-efficient schemes for implementing logical H and S gates transversally on rotated surface codes with reconfigurable neutral atom arrays. For logical H gates, we…
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…
Leapfrogging Sycamore: Harnessing 1432 GPUs for 7 Faster Quantum Random Circuit Sampling
Xian-He Zhao, Han-Sen Zhong, Feng Pan +10
Random quantum circuit sampling serves as a benchmark to demonstrate quantum computational advantage. Recent progress in classical algorithms, especially those based on tensor netw…
Unconditionally decoherence-free quantum error mitigation by density matrix vectorization
Zhong-Xia Shang, Zi-Han Chen, Cai-Sheng Cheng
