[Unreleased]
Later
- Additional entangling gates (Toffoli, SWAP)
- Circuit builder API
- QASM export functionality
1.0.0 - 2026-02-15
Added
- N-qubit state registers replacing single-qubit representation
- Rotation gates (Rx, Ry, Rz) for arbitrary angle rotations
- CNOT (controlled-NOT) gate for entanglement
- Partial measurement with state collapse and renormalization on n-qubit registers
- Tests for CNOT gate (basic flip and Bell state)
- Tests for measurement (collapse, normalization, multi-qubit)
Changed
- Complete architecture rewrite from single-qubit (
Qubit) to n-qubit registers (Register) - All gates now operate on
Register.qreg with a target qubit index - Measurement module rewritten for n-qubit registers
- Examples updated to use the new Register API
Removed
Qubit module (replaced by Register)- S and T phase gates (to be re-added in a future release)
0.1.6 - 2026-01-26
Added
Changed
- Migrating to ocaml-raylib for bloch sphere visualisation
Removed

- discover.ml file
0.1.5 - 2025-12-13
Added
- S (phase) gate
- T (π/8) gate

0.1.4 - 2025-12-13
Fixed
- macOS ARM64 support: Fixed OpenGL/GLUT header detection on Apple Silicon Macs by using /opt/homebrew/include instead of /usr/local/include

0.1.1 - 2025-11-1
Fixed
- Y gate test
