Native gates and operations

Each processor family has a native gate set. By default, the systems in each family only support running the gates and operations in the native gate set. Thus, every gate in the circuit must be translated (by the transpiler) to the elements of this set.

You can view the native gates and operations for a system either with Qiskit® or on the IBM Quantum™ Platform Compute resources page.

Basis gates

The terms native gates and basis gates are often used interchangeably. However, you can specify a different set of basis gates to use, while the native gate set never changes. For information about changing the basis gates, see the Represent quantum computers topic.


Find the native gate set for a system

With Qiskit

 
from qiskit_ibm_runtime import QiskitRuntimeService
 
service = QiskitRuntimeService(channel="ibm_quantum")
 
for backend in service.backends():
    config = backend.configuration()
    if "simulator" in config.backend_name:
        continue
    print(f"Backend: {config.backend_name}")
    print(f"    Processor type: {config.processor_type}")
    print(f"    Supported instructions:")
    for instruction in config.supported_instructions:
        print(f"        {instruction}")
    print()

On IBM Quantum Platform

Select any system on the Compute resources(opens in a new tab) tab. The default gates for that system are listed under Details. Note that the non-unitary operations are not listed here; use the method in Qiskit described above to see all native gates and operations for a system.

The init_qubits flag

The init_qubits flag, set as a primitive execution option, controls whether qubits are reset to the zero state at the start of each circuit. Its default value is True, indicating that the qubits should be reset. If False, the qubits will begin in the final state from the previous shot, and you must manually insert resets if you want to reset them to the zero state. If a job consists of multiple circuits, then the shots are executed in a "round-robin" fashion. That is, each circuit will be executed in sequence to obtain one shot from each circuit. This process is then repeated until the requested number of shots has been obtained from all circuits.
