Decoupling 2D translation-invariant topological CSS codes
Yifei Wang, Zhongyi Ni, Mingxin He +2
Two-dimensional translation-invariant topological CSS codes on qubits are known to be locally equivalent, after coarse-graining, to stacks of toric codes. However, existing constru…
Realified tensor networks: quantum circuit simulation on real-valued matrix accelerators
Yusheng Zhao, Xiwei Pan, Enji Xiong +2
Tensor-network contraction simulates quantum circuits, but modern matrix accelerators (NPUs, TPUs) expose only real GEMM pipelines, so the complex networks of quantum simulation mu…
Measurement-Free Toric-Code Memory in Array Globally Controlled Rydberg Array
Han Wang, Yusheng Zhao, Xiuhao Deng +1
The central prerequisite of any fault-tolerant quantum architecture is a quantum memory: a block of encoded physical qubits whose logical state is actively preserved against noise…
High-Level Surface Code Decoding via Parallel FFNNs on CIM Platforms
Hao Wang, Erjia Xiao, Wenbo Mu +9
Due to the high sensitivity of qubits to environmental noise, which leads to decoherence and information loss, active quantum error correction(QEC) is essential. Surface codes repr…
