- t2star_circuits(num_of_gates, gate_time, qubits, nosc=0)[소스]¶
Generate circuits for T_{2}^{*} measurement.
Each circuit consists of a Hadamard gate, followed by a sequence of identity gates, a phase gate (with a linear phase), and an additional Hadamard gate.
- 매개변수
num_of_gates (
Union
[List
[int
],array
]) – the number of identity gates in each circuit. Must be in an increasing order.gate_time (
float
) – time of running a single identity gate.qubits (
List
[int
]) – indices of the qubits whose T_{2}^{*}〈s are to be measured.nosc (
int
) – number of oscillations to induce using the phase gate
