qcaml.0.1.1

Experimental OCaml library for quantum computing simulation
QCaml is a lightweight OCaml library for experimenting with quantum states,
gates and measurements. It provides tools for learning quantum computing
concepts and visualizing qubit states on the Bloch sphere.

Features:

• Single qubit state representation with complex amplitudes
• Fundamental quantum gates (Hadamard, Pauli-X/Y/Z)
• Quantum measurements with probabilistic state collapse
• Interactive Bloch sphere visualization using OpenGL/GLUT
• Comprehensive test suite

This bound needs adjustment.
On the lower bounds search
- downgrade dune 3.20.2 to 3.6.2 [required by qcaml]
changes it from compiling cleanly to failing with

I suggest just recreating locally and starting off a bisection, starting off somewhere in the middle, e.g., with
opam install dune.3.17.2 and seeing if things compile cleanly with each investigated version.

There's also something with the version.
This now refers to v0.1.2.tar.gz yet the opam file is named packages/qcaml/qcaml.0.1.1/opam

[elias-utf8]

Oh sorry, I didnt see your review so I created a new PR on a new release with the corrections for 0.1.2 here but I didnt did the biisection.

[jmid]

OK thanks, that takes care of the package versioning 👍
The new PR's CI run also fails the lower-bounds search for the same reason 🙂

[elias-utf8]

Haha of course :)) And yes, I'll keep you updated in the new PR.
