I'm trying to run a quantum circuit created in Qiskit, on Ionq Device using qiskit_braket_provider. Getting some error while transpiling the circuit because circuit contains a qiskit.initialize instruction. Is there any alternative for initialize function in aws braket? Any other way out of this problem?
This problem can be recreated as:
Code:
qc = QuantumCircuit(2)
st = random_statevector(2)
qc.initialize(st, 0)
qc.x(1)
tqc = transpile(qc,backend = ionq)
Error:
TranspilerError Traceback (most recent call last)
