qandle.ansaetze.stronglyentangling module

class qandle.ansaetze.stronglyentangling.StronglyEntanglingLayer(qubits: ~typing.List[int], num_qubits_total: int | None = None, depth: int = 1, rotations=['rz', 'ry', 'rz'], q_params=None, remapping: ~typing.Callable | None = <function tanh>)

Bases: UnbuiltAnsatz

A strongly entangling layer, inspired by this paper. Consists of a series of single-qubit rotations on each qubit specified in the qubits parameter, followed by a series of CNOT gates. A higher depth will increase the expressivity of the circuit at the cost of more parameters and a linear increase in runtime.

build(*args, **kwargs) → BuiltAnsatz

Builds the operator, i.e. converts it to a torch.nn.Module.

decompose() → List[UnbuiltOperator]

to_qasm() → QasmRepresentation

Returns the OpenQASM2 representation of the operator.
