New :class:`qiskit.extensions.HamiltonianGate` and
|
|
:meth:`qiskit.circuit.QuantumCircuit.hamiltonian()` methods are
|
|
introduced, representing Hamiltonian evolution of the circuit
|
|
wavefunction by a user-specified Hermitian Operator and evolution time.
|
|
The evolution time can be a :class:`~qiskit.circuit.Parameter`, allowing
|
|
the creation of parameterized UCCSD or QAOA-style circuits which compile to
|
|
``UnitaryGate`` objects if ``time`` parameters are provided. The Unitary of
|
|
a ``HamiltonianGate`` with Hamiltonian Operator ``H`` and time parameter
|
|
``t`` is :math:`e^{-iHt}`.
