Qlass

Quantum algorithms for photonic devices, developed as part of the Quantum Glass-based Photonic Integrated Circuits (QLASS) project. It provides tools to compile Qiskit quantum circuits to Perceval processors, enabling execution on photonic hardware. A core feature is the implementation of the Variational Quantum Eigensolver (VQE) tailored for photonic quantum computers, including specific ansatz implementations. The package also includes quantum chemistry tools for generating and manipulating Hamiltonians, useful for VQE applications. It integrates with established libraries such as scipy, pyscf, qiskit-nature, qiskit, and perceval. The package is structured into modules covering compilation, quantum chemistry, VQE, and utilities.
