CROTGateSet

class CROTGateSet(n_qubits, **properties)

Star-topology gate set with single-qubit rz/r and a native crot.

The two-qubit crot acts on every star edge (0, target). This class is the gate-level description only; the matching pulse-level description lives in SimphonyBackend.

Parameters:

• n_qubits (int) – Number of qubits in the star register, including the central qubit 0.

• spam_qubits – Qubits the device resets and reads out together, (0,) by default. StarTopologyGateSet describes them.

Attributes

gate_durations	Return the duration of every native gate that has one.
gate_errors	Return the error of every native gate that has one.
gate_types	Return the native gate families.
native_gates	Return the native gates supported by the gate set.
placements	Return where a native entangler sits, and which one.
reserved_qubits_by_gate	Return the qubits every native gate reserves while it runs.
routing_edges	Return the topology entries usable for pairwise routing.
spam_qubits	Return the qubits the device resets and reads out together.
topology	Return the qubit set every native entangling gate can be built on.

Methods

gate_duration(gate)	Return a native gate's duration, or None when it has none.
gate_error(gate)	Return a native gate's average gate infidelity on its own qubits, or None when it has none.
lower_resets(circuit)	Rewrite a circuit's resets as the resets the device performs.
pauli_readout_native(pauli_readout[, ...])	Return the native readout a requested Pauli string is realized through by default.
pauli_readouts_native()	Return every Pauli string the hardware reads out directly.
random_circuit(n_gates[, seed])	Generate a random circuit drawn from the native gate set.
reserved_qubits(gate)	Return the qubits a native gate reserves while it runs.
reset_circuit(qubits)	Build the circuit resetting these qubits to \(|0\rangle\).
with_properties(*[, ...])	Return a copy of this gate set with new errors, durations or reserved qubits.
