Here, we study how this activation protocol can be used to entangle the starting systems themselves via entanglement swapping through a measurement on the ancillae. Furthermore, we bound the relative entropy of quantumness (a naturally arising measure of non-classicality in the scheme of Piani et al. above) for a special class of separable states, the so-called classical–quantum states. In particular, we fully characterize the classical–quantum two-qubit states that are maximally non-classical. article_type: original author: - first_name: Sevag full_name: Gharibian, Sevag id: '71541' last_name: Gharibian orcid: 0000-0002-9992-3379 - first_name: MARCO full_name: PIANI, MARCO last_name: PIANI - first_name: GERARDO full_name: ADESSO, GERARDO last_name: ADESSO - first_name: JOHN full_name: CALSAMIGLIA, JOHN last_name: CALSAMIGLIA - first_name: PAWEŁ full_name: HORODECKI, PAWEŁ last_name: HORODECKI citation: ama: Gharibian S, PIANI M, ADESSO G, CALSAMIGLIA J, HORODECKI P.

Here we define a natural approximation version of the QMA-complete local Hamiltonian problem and initiate its study. We present two main results. The first shows that a non-trivial approximation ratio can be obtained in the class NP using product states. The second result (which builds on the first one), gives a polynomial time (classical) algorithm providing a similar approximation ratio for dense instances of the problem. The latter result is based on an adaptation of the "exhaustive sampling method" by Arora et al. [J. Comp. Sys. Sci. 58, p.193 (1999)] to the quantum setting, and might be of independent interest. author: - first_name: Sevag full_name: Gharibian, Sevag id: '71541' last_name: Gharibian orcid: 0000-0002-9992-3379 - first_name: Julia full_name: Kempe, Julia last_name: Kempe citation: ama: 'Gharibian S, Kempe J.

In 2003, Gurvits showed that this problem is NP-hard if rho is located within an inverse exponential (with respect to dimension) distance from the border of the set of separable quantum states. In this paper, we extend this NP-hardness to an inverse polynomial distance from the separable set. The result follows from a simple combination of works by Gurvits, Ioannou, and Liu. We apply our result to show (1) an immediate lower bound on the maximum distance between a bound entangled state and the separable set (assuming P != NP), and (2) NP-hardness for the problem of determining whether a completely positive trace-preserving linear map is entanglement-breaking. article_type: original author: - first_name: Sevag full_name: Gharibian, Sevag id: '71541' last_name: Gharibian orcid: 0000-0002-9992-3379 citation: ama: Gharibian S.

To this end, we derive and discuss closed formulae for the maximal such distance achievable for three cases of interest: (pseudo)pure quantum states, Werner states, and two-qubit states. What makes this criterion interesting, as we show here, is that it surprisingly displays behavior similar to recent anomalies observed for non-locality measures in higher dimensions, as well as demonstrates an equivalence to the CHSH inequality for certain classes of two-qubit states.

Rev. Lett. 81, 5672 (1998)]. To do so, we consider two known non-classicality criteria. The first quantifies disturbance of a quantum state under locally noneffective unitary operations (LNU), which are local unitaries acting invariantly on a subsystem. The second quantifies measurement induced disturbance (MID) in the eigenbasis of the reduced density matrices. We study the role of both figures of non-classicality in the exponential speedup of the DQC1 model and compare them vis-a-vis the interpretation provided in terms of quantum discord. In particular, we prove that a non-zero quantum discord implies a non-zero shift under LNUs. We also use the MID measure to study the locking of classical correlations [Phys. Rev. Lett. 92, 067902 (2004)] using two mutually unbiased bases (MUB). We find the MID measure to exactly correspond to the number of locked bits of correlation.
