Change
Fixed a bug where the num_qubits information would disappear after the calculation, even though
h = Hamiltonian(num_qubits=3)
.Desciption
The
__add__
and__mul__
ofHamiltonian
now inherit the information before the operation.In addition, when performing an operation on two Hamiltonians, the one with the larger num_qubits is selected to be inherited.
