String-based Pauli algebraic manipulations

Setup (pypi) :

pip install stringebraic

or:

python -m pip install stringebraic

This requires Python 3.8 or newer versions.

How to use:

        stringebraic <input_string_list.pkl> <input_string_coeff_list.pkl> <pauli_matrix_list.pkl> <pauli_coeff_list.pkl>

input_string_list.pkl – A pickle file containing a list of bitstrings that compose the quantum state.
input_string_coeff_list.pkl – A pickle file containing a list of coefficients that compose the quantum state.
pauli_matrix_list.pkl – A pickle file containing a list of Pauli strings that compose the Hamiltonian.
pauli_coeff_list.pkl – A pickle file containing a list of Pauli coefficients that compose the Hamiltonian.

stringebraic (String-based Pauli algebraic manipulations)

Represents a Hamiltonian as a sum of Pauli strings and a quantum state as a sum of bitstrings.
Allows for a variety of operations using these strings, such as matrix-vector multiplication and inner products.
