1.0.0 2026-06-25: Initial release
1.0.1 2026-06-25: Fixed phase gate. Quantum archaeology now ignores global phase, as it should.

[unitary]

Version 1.0.1 fixes two bugs.

There was a bug with the phase gate. If no phase was specified, then the phase was not correctly applied. I believe it was causing the coefficients for the state to become NaN, but I am not sure. In this version, if no phase is specified then the phase of |1> is multiplied by i.

There was an oversight in the implementation of quantum archaeology. Previously, the quantum accelerator compared the states by comparing both coefficients. Now, the quantum accelerator compares the qubit states only up to global phase, since states which differ only by global phase are physically indistinguishable.
