Non-Abelian Geometric Quantum Memory with Atomic Ensemble
Y. Li, P. Zhang, P. Zanardi +1
We study a quantum information storage scheme based on an atomic ensemble with near (also exact) three-photon resonance electromagnetically induced transparency (EIT). Each 4-level…

Universal control of quantum subspaces and subsystems
P. Zanardi, S. Lloyd
We describe a broad dynamical-algebraic framework for analyzing the quantum control properties of a set of naturally available interactions. General conditions under which universa…
