TensorCircuit-NG v1.10.0

This release adds new tensor-network algorithms and expands TensorCircuit-NG’s matrix-function and spectral tools, alongside a broad set of correctness and stability improvements.

Highlights

  • Added tensorcircuit.tnalg experimental module with fixed-shape JAX implementations of MPS TEBD, one-site TDVP, and one-site DMRG. It supports dense and Abelian block-buffer PyTree states, Pauli-string MPO builders, checkpoints, and interoperability with legacy MPS states.

  • Expanded matrix-function and spectral methods for Krylov/SLQ, Chebyshev/KPM, and Taylor calculations, including reusable JIT- and AD-compatible queries and density-of-states, thermal, and response APIs.

  • Unified the public time-evolution entry points with the matrix-function implementation.

Fixes and improvements

  • Corrected complex-gradient handling across JAX, PyTorch, and TensorFlow, and improved DLPack transfers for noncontiguous PyTorch tensors.

  • Fixed circuit behavior involving AnalogCircuit initial states and composition, periodic Line1D weights, QAOA Ising cost angles, and time-dependent analog inversion.

  • Improved measurement, observable, and noise semantics across ZX and stabilizer circuits, including Stim imports, MPP readout noise, and sampled Pauli expectations.

  • And many more stability improvements and bug fixes...
