Abstract

This paper experimentally realize a new method for shortcuts to adiabaticity, number operator based inverse engineering method (NOBIE), using quantum computers built with transmon qubits. Digitized control pulses are programmed in an open source software development kit, qiskit, to execute the shortcut protocols. The obtained results shows the robustness of the NOBIE method, even though it is tested for an effective Hamiltonian of a qubit irrespective of the interaction with other qubits and noise associated with the control pulses.
