Multigeometry and expressive boundaries

[gcalin]

Features

Parallel Semantics

• ABQLBM and LQLGA now support parallel semantics. The development is mostly focusing on ABQLBM because we can run larger grids.
• Parallel semantics include:
  • Initial Conditions
  • Boundary Conditions
  • Updating boundary conditions after creating the lattice
  • Adaptive register logic to avoid unnecessary qubits
  • No change necessary to the high level API, the parallel semantics are inferred based on the specification

Expressive boundary conditions

• ABQLBM now supports the YMonomial BC specification. Limited support only to y [comp] x^2 for now, as this is a proof of concept
• Full support for parsing, stl meshing, serialization.

Demos

• Updated existing demos to include smaller (faster) simulations
• Added demos for parallel ICs and BCs in the ABQLBM

Bugfixes

• Fixed a bug in the specification of the MSQLBM demo
• Fixed a bug where transpiling CH without decomposing first resulted in incorrect results
• Fixed versions for qiskit and qiskit_ibm_runtime dependencies as newer minor versions include major API or functionality changes.
