class qandle.ansaetze.stronglyentangling_budget.StronglyEntanglingLayerBudget(num_qubits_total: int, qubits: ~typing.List[int] | None = None, param_budget: int = 1, control_gate=<class 'qandle.operators.CNOT'>, control_gate_spacing=1, rotations=['rz', 'ry'], remapping: ~typing.Callable | None = <function tanh>)

Bases: BuiltAnsatz

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 control gates. Instead of specifying a depth, a param_budget is specified, which determines the number of parameters in the circuit. The control gates are inserted every control_gate_spacing layers, quickly allowing to change the entanglement structure of the circuit.

decompose() → List[UnbuiltOperator]

forward(x)

Applies the operator to the state.

to_qasm() → QasmRepresentation

Returns the OpenQASM2 representation of the operator.
