Accuracy of the adiabatic-impulse approximation for closed and open quantum systems
Michael Tomka, Lorenzo Campos Venuti, Paolo Zanardi
We study the adiabatic-impulse approximation (AIA) as a tool to approximate the time evolution of quantum states, when driven through a region of small gap. The AIA originates from…
Coherence generating power of quantum dephasing processes
Georgios Styliaris, Lorenzo Campos Venuti, Paolo Zanardi
We provide a quantification of the capability of various quantum dephasing processes to generate coherence out of incoherent states. The measures defined, admitting computable expr…
Noise suppression via generalized-Markovian processes
Jeffrey Marshall, Lorenzo Campos Venuti, Paolo Zanardi
It is by now well established that noise itself can be useful for performing quantum information processing tasks. We present results which show how one can effectively reduce the…
Quantum coherence generating power, maximally abelian subalgebras, and Grassmannian Geometry
Paolo Zanardi, Lorenzo Campos Venuti
We establish a direct connection between the power of a unitary map in -dimensions () to generate quantum coherence and the geometry of the set of maximal…
Topological Protection of Coherence in a Dissipative Environment
Lorenzo Campos Venuti, Zhengzhi Ma, Hubert Saleur +1
One dimensional topological insulators are characterized by edge states with exponentially small energies. According to one generalization of topological phases to non-Hermitian sy…
