Controlling and engineering a quantum state in a multi-qubit system employing the quantum Zeno effect

Abstract

Controlling quantum jumps is crucial for reliable quantum computing. In this work, we demonstrate how the quantum Zeno effect can be applied to a two qubit system interacting with an ancilla which is a component of surface code architecture used to control undesired transitions. Further, we show that by designing the interaction and tuning measurement frequency, the quantum Zeno effect can be used to achieve the desired target state in both single-qubit and two qubit systems.
