Qubit State Algebra

v0.1.6

QSA

A dependency-free C++20 numerical core for quantum state work using structural representations, local component merging, separability recovery, operation plans, and QSC state files.

Documented capabilities

  1. 01Bloch-cell, sparse, dense, symmetry, and amplitude-class state representations
  2. 02Standard gates, arbitrary 2x2 and 4x4 operations, measurement, and noise trajectories
  3. 03Gate fusion, parallel register batches, bulk readout, and save/restore through QSC

QSA 0.1.6

Measured release workloads

Results apply to the named benchmark and representation. They are not a universal multiplier for arbitrary circuits.
