remove_barriers#

remove_barriers(qc: QuantumCircuit) → QuantumCircuit[source]#

Return a copy of qc with all barrier instructions removed.

Parameters:

qcQuantumCircuit: The input circuit, potentially containing barrier instructions.

Returns:

QuantumCircuit: A new circuit identical to qc but without any barriers.

Examples

Remove a barrier from a circuit:

>>> from qrisp import QuantumCircuit, PassManager
>>> from qrisp import remove_barriers
>>> qc = QuantumCircuit(2)
>>> qc.h(0)
>>> qc.barrier()
>>> qc.cx(0, 1)
>>> print(qc)
