Computational complexity of time-dependent density functional theory
James D. Whitfield,Man-Hong Yung,Man-Hong Yung,David G. Tempel,Sergio Boixo,Alán Aspuru-Guzik +5 more
TL;DR: A V-representability parameter is introduced which diverges at the boundary of the existence domain and serves to quantify the numerical difficulty of constructing the Kohn–Sham potential and a polynomial time quantum algorithm is presented to generate the time-dependent Kohn-Sham potential with controllable error bounds.
Linear-algebraic bath transformation for simulating complex open quantum systems
TL;DR: In this paper, a bath partition strategy is proposed to reduce the coupling strength of the system-bath coupling strength, and the non-interacting star-bath is transformed into a set of weakly coupled multiple parallel chains.

Unification of witnessing initial system-environment correlations and witnessing non-Markovianity
TL;DR: In this article, the role of state preparation in witnessing violations of contractivity of open quantum system dynamics is investigated, where a witness that detects dynamical maps with initial system-environment correlations is an upper bound to a witness of non-Markovianity.

TL;DR: In this paper, a case study for encoding related combinatorial optimization problems in a form suitable for adiabatic quantum optimization is presented, where the authors demonstrate how to constrain and embed lattice heteropolymer problems using several strategies, each striking a unique balance between number of constraints, complexity of constraints and number of variables.
