This is a library that I started developing to create faster workflows, firstly for variational quantum algorithms, using qiskit.
The main feature is the volta.observables.sample_hamiltonian which enables you to do easy evaluation of the expectation value for a hamiltonian defined using opflow and a quantum circuit.
I plan to implement Hamiltonian Simulation algorithms as well as noise mitigation for this package.
