🐛 [NA] Dropped Global Hadamard Gate #876
Description
System and Environment Information
MAC OS 15.6.1
MQT QMAP 3.4.0dev@9c84575
Bug Description
When compiling a circuit with a global Hadamard Gate, this is dropped and does not exist in the resulting output.
Steps to Reproduce
Run the following contract:
from qiskit import QuantumCircuit
from mqt.core import load
from mqt.qmap.na.zoned import RoutingAgnosticCompiler, RoutingAwareCompiler
from mqt.qmap.na.zoned import ZonedNeutralAtomArchitecture
def global_h(num_qubits):
""":returns: a global ry gate"""
qc = QuantumCircuit(num_qubits)
qc.h(range(num_qubits))
return qc.to_gate(label="H")
qc = QuantumCircuit(5)
qc.append(global_h(5), range(5))
circ = load(qc)
arch = ZonedNeutralAtomArchitecture.from_json_string("""{
