quri_parts.circuit.transpile.clifford_approximation module

class quri_parts.circuit.transpile.clifford_approximation.CliffordApproximationTranspiler(*args, **kwargs)

Bases: GateDecomposer

CircuitTranspiler, which replaces the non_clifford gate into sequence of non-parametric Clifford gates.

If the input gate has angles, this transpiler replaces them with the closest value in the set \(\{\pi n /2| n\in\mathbb{Z}\}\). Then by using the rotation gate transpilers, it is decomposed into a sequence of non-parametric Clifford gates.

is_target_gate(gate: QuantumGate) → bool

Determine if a given gate is subject to decomposition.

Parameters:

gate – Gates in the circuit that are scanned from the front.

decompose(gate: QuantumGate) → Sequence[QuantumGate]

Describe the specific decomposition process. Only the target gates satisfying is_target_gate() method are passed.

Parameters:

gate – The gates to be decomposed.
