Arya Meenakumari Biju: Performing calibration Experiments on a real Quantum Computer using Qiskit Pulse

SCCS Colloquium |


Calibrating the qubits on a quantum computer backend by sending in a series of pulses. Qiskit is an open source framework for programming Quantum Computers. Using Qiskit, quantum circuits can be built, simulated and executed on quantum devices. Qiskit Pulse provides a language for specifying pulse level control (i.e. control of the continuous time dynamics of input signals) of a general quantum device independent of the specific hardware implementation.In this experiment,we begin by searching for the qubit frequency.The qubit frequency is the difference in energy between the ground and excited states, which we label as the | 0〉 and | 1〉states, respectively.
This frequency will be crucial for creating pulses which perform a specified set of quantum operations on the qubit like finding the amplitude of a pi pulse using rabi experiments, finding the drive amplitude of a pi/2 pulse etc. We will also find the T1 time of the qubit. The T1 time of a qubit is the time it takes for a qubit to
decay from the excited state to the ground state. It is important because it limits the duration of meaningful programs we can run on the quantum computer. We will finally extract the results and plot them using matplotlib.
