Experimentally implementable criteria revealing substructures of genuine multipartite entanglement

Marcus Huber, Hans Schimpf, Andreas Gabriel +3

We present a general framework that reveals substructures of genuine multipartite entanglement. Via simple inequalities it is possible to discriminate different sets of multipartit…

Lorentz invariance of entanglement classes in multipartite systems

Marcus Huber, Nicolai Friis, Andreas Gabriel +2

We analyze multipartite entanglement in systems of spin-1/2 particles from a relativistic perspective. General conditions which have to be met for any classification of multipartit…

Optimal unambiguous comparison of two unknown squeezed vacua

Stefano Olivares, Michal Sedlak, Peter Rapcan +2

We propose a scheme for unambiguous state comparison (USC) of two unknown squeezed vacuum states of an electromagnetic field. Our setup is based on linear optical elements and phot…

Open system dynamics of simple collision models

Mario Ziman, Vladimír Bužek

A simple collision model is employed to introduce elementary concepts of open system dynamics of quantum systems. In particular, within the framework of collision models we introdu…

Approximating incompatible von Neumann measurements simultaneously

Teiko Heinosaari, Maria Anastasia Jivulescu, Daniel Reitzner +1

We study the problem of performing orthogonal qubit measurements simultaneously. Since these measurements are incompatible, one has to accept additional imprecision. An optimal joi…

Simulation of Classical Thermal States on a Quantum Computer: A Transfer Matrix Approach

Man-Hong Yung, Daniel Nagaj, James D. Whitfield +1

We present a hybrid quantum-classical algorithm to simulate thermal states of a classical Hamiltonians on a quantum computer. Our scheme employs a sequence of locally controlled ro…

Single-shot discrimination of quantum unitary processes

Mario Ziman, Michal Sedlák

We formulate minimum-error and unambiguous discrimination problems for quantum processes in the language of process positive operator valued measures (PPOVM). In this framework we…

Quantum-state preparation with universal gate decompositions

Martin Plesch, Časlav Brukner

In quantum computation every unitary operation can be decomposed into quantum circuits-a series of single-qubit rotations and a single type entangling two-qubit gates, such as cont…

Universal 2-local Hamiltonian Quantum Computing

Daniel Nagaj

We present a Hamiltonian quantum computation scheme universal for quantum computation (BQP). Our Hamiltonian is a sum of a polynomial number (in the number of gates L in the quantu…

Unfrustrated Qudit Chains and their Ground States

Ramis Movassagh, Edward Farhi, Jeffrey Goldstone +3

We investigate chains of 'd' dimensional quantum spins (qudits) on a line with generic nearest neighbor interactions without translational invariance. We find the conditions under…
