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
