Qubit dynamics driven by smooth pulses of finite duration
Ivo S. Mihov, Nikolay V. Vitanov
We present a study of the dynamics of a qubit driven by a pulsed field of finite duration. The pulse shape starts and ends linearly in time. The most typical example of such a shap…
Motional state analysis of a trapped ion by ultra-narrowband composite pulses
Marion Mallweger, Milena Guevara-Bertsch, Boyan T. Torosov +7
In this work, we present a method for measuring the motional state of a two-level system coupled to a harmonic oscillator. Our technique uses ultra-narrowband composite pulses on t…
Multipass Quantum Process Tomography: Precision and Accuracy Enhancement
Stancho G. Stanchev, Nikolay V. Vitanov
We introduce a method to enhance the precision and accuracy of Quantum Process Tomography (QPT) by mitigating the errors caused by state preparation and measurement (SPAM), readout…
Creation of coherent superpositions of Raman qubits by using dissipation
Andon A. Rangelov, Nikolay V. Vitanov
We show how to create coherent superpositions between two ground states of Lamda quantum system of three states, among which the middle one decays. The idea is to deplete the popul…
