Proof of the Error Scaling for Universally Robust Dynamical Decoupling Sequences
Domenico D'Alessandro, Phattharaporn Singkanipa, Daniel Lidar
Universally robust dynamical decoupling (UR) sequences were proposed to compensate pulse imperfections arising from arbitrary experimental parameters while achieving high-order…
Quantum Robust Control using Geometric Optimal Control Theory
Francesca Albertini, Domenico D'Alessandro
In this paper, we demonstrate an approach to quantum robust control based on the tools of geometric optimal control. The central objects of interest are the sensitivity functions d…
Quantum Optimal Control of a Lambda System in the Density Matrix Formulation
Julia Cen, Domenico D'Alessandro
In various physical implementations of quantum information processing, qubits are realized in a Lambda type system configuration as two stable lower energy levels coupled indirectl…
Entanglement of Quantum States which are Zero on the Symmetric Sector
Domenico D'Alessandro
We consider a quantum system of n qudits and the Clebsch-Gordan decomposition of the associated Hilbert space. In this decomposition, one of the subspaces is the so-called symmetri…
