ec07b8ea86 refactored execute. The observable is now passed as lists of operators, coefficients and qubits. Implemented functions for handling conversion from Pauli string to quimb operator and coefficients. Fixed: error in parameters handing in expectation. Fixed GATE_MAP to match the common observables 2025-09-23 00:41:19 +02:00

5e141b200a feat: added expectiation function to compute expectation value of a symbolic hamiltonian using quimb backend. Added function to convers Qibo symbolic hamiltonian in Quimb compatible list of observables. Added a grouping function to combine in a single list local observables acting on the same qubits, to allow Quimb to compute them all in a single contraction (not working for MPS ansatz). Also added argument in setup_backend_specifics to specify an optimizer. 2025-09-08 18:25:08 +02:00
