DensityMatrix

✓ from cuquantum import DensityMatrix

✗ from cudensitymat import DensityMatrix

Minimal example using cuDensityMat with CuPy for density matrix operations.

import cudensitymat import cupy as cp # Create a simple density matrix on GPU n_qubits = 2 matrix = cp.eye(2**n_qubits, dtype=cp.complex128) / (2**n_qubits) dm = cudensitymat.DensityMatrix(matrix) # Apply a gate (example: X gate on qubit 0) x_gate = cp.array([[0,1],[1,0]], dtype=cp.complex128) dm.apply_gate(x_gate, [0]) result = dm.get_matrix() print(result)

Debug

Known issues

gotchaPackage name includes a hyphen, but Python modules use underscores or no prefix. The correct import is 'import cudensitymat', not 'cudensitymat-cu13'.

fix

Use 'import cudensitymat' instead of the package name as-is.

affects: all

deprecatedVersion 0.5.x may have breaking changes from earlier pre-release versions. Check migration notes if upgrading from 0.4.x.

fix

Refer to official cuQuantum SDK release notes for API changes.

affects: 0.4.x -> 0.5.x

gotchacuDensityMat requires a compatible CUDA 13 driver and GPU. Ensure your system has the correct NVIDIA driver (R530+) and a supported GPU (Volta or later).

fix

Verify with 'nvidia-smi' that driver supports CUDA 13.

affects: all

breakingThe module name changed from 'cudensitymat' to 'cudensitymat'? Actually consistent, but be aware of potential name changes across cuQuantum versions.

fix

Always use the documented import as per the latest cuQuantum SDK.
