Implementing Custom Gates by using Qiskit Pulse in Qiskit 1.0.0

Implementing Custom Gates by using Qiskit Pulse in Qiskit 1.0.0 Ask Question Asked 2 years, 1 month ago Modified today Viewed 264 times 1 I'm using Qiskit 1.0.0. I'm trying to define a custom gate from a certain wavefunction and insert it in a quantum circuit that I want to run and measure the counts. The relevant code for the question is as follows: backend = FakePerth() custom_gate_ch1 = Gate('ch1', 1, []) circ = QuantumCircuit(4) passmanager = generate_preset_pass_manager(optimization_level=1, backend=backend) with builder.build() as ch1_gate: builder.play(wave, DriveChannel(0)) backend.target.add_instruction( custom_gate_ch1, {(0,): InstructionProperties(calibration=ch1_gate)}, ) circ.append(custom_gate_ch1, [0]) circ.measure_all() circ = passmanager.run(circ) tqc = transpile(circ, backend, scheduling_method='asap') counts = backend.run(tqc).result().get_counts() With this code, I'm able to obtain the transpiled circuits correctly, but when I try to run it I get the following error: qiskit.providers.basic_provider.exceptions.BasicProviderError: 'basic_simulator encountered unrecognized operation "ch1"' Where am I going wrong? qiskitopenpulse Share Improve this question Follow asked Feb 20, 2024 at 15:06 Roberto Schiattarella 1956 6 bronze badges Add a comment 1 Answer Sorted by: Highest score (default) Date modified (newest first) Date created (oldest first) 0 have you found a solution? I think that there is nothing wrong in particular with your code. Just the transition to Qiskit 1.0.x did not happen as smoothly as hoped and not all functionality was kept. I am facing the same issue with a sub-circuit including parameters for BasicSimulator. I found the solution by decomposing the circuit with abstract gates/circuits into the basic gate set before sending it to the BasicSimulator. Maybe it helps you. decomposed = transpile(qc, basis_gates=['cx', 'id', 'rz', 'sx', 'x']) backend = BasicSimulator() job_results = backend.run(decomposed, shots=1).result() Share Improve this answer Follow answered Mar 13, 2024 at 9:57 J.D. 1 As it’s currently written, your answer is unclear.
