0.1.3 - 2025-11-2

Changed

• Update dune version lower bound to 3.17

0.1.2 - 2025-11-2

Fixed

• Fixed a critical build failure on Windows/MinGW platforms caused by platform-specific OpenGL library naming differences.

0.1.1 - 2025-11-1

Fixed

• Y gate test
• Type error in apply_gate.ml line 8 - Qubit.print () q returns string but Printf.printf expects a format string

0.1.0 - 2025-10-29

Added

• Initial public release
• Single qubit state representation with complex amplitudes
• Qubit state constructors: zero(), one(), plus(), minus()
• Pauli gates: X, Y, Z
• Hadamard gate (H)
• Quantum measurement with probabilistic collapse
• Interactive Bloch sphere visualization using OpenGL/GLUT
• Complex number module with arithmetic operations
• Comprehensive test suite using Alcotest
• Example programs demonstrating library usage
• Apache 2.0 license

Known Limitations

• Single-qubit operations only (no multi-qubit support)
• Limited gate set
• No circuit builder API yet
• Bloch sphere visualization can be a little buggy
