Necessary and sufficient conditions for state-independent measurement contextual scenarios
Ravishankar Ramanathan, Pawel Horodecki
The problem of identifying measurement scenarios capable of revealing state-independent contextuality in a given Hilbert space dimension is considered. We begin by showing that for…
Local random quantum circuits are approximate polynomial-designs - numerical results
Piotr Ćwikliński, Michał Horodecki, Marek Mozrzymas +2
We numerically investigate the statement that local random quantum circuits acting on n qubits composed of polynomially many nearest neighbour two-qubit gates form an approximate u…
Collectibility for Mixed Quantum States
Łukasz Rudnicki, Zbigniew Puchała, Paweł Horodecki +1
Bounds analogous to entropic uncertainty relations allow one to design practical tests to detect quantum entanglement by a collective measurement performed on several copies of the…
Constructive entanglement test from triangle inequality
Łukasz Rudnicki, Zbigniew Puchała, Paweł Horodecki +1
We derive a simple lower bound on the geometric measure of entanglement for mixed quantum states in the case of a general multipartite system. The main ingredient of the presented…
Conjectured strong complementary-correlations tradeoff
Andrzej Grudka, Michał Horodecki, Paweł Horodecki +3
We conjecture new uncertainty relations which restrict correlations between results of measurements performed by two separated parties on a shared quantum state. The first uncertai…
Analytical progress on symmetric geometric discord: Measurement-based upper bounds
Adam Miranowicz, Pawel Horodecki, Ravindra W. Chhajlany +2
Quantum correlations may be measured by means of the distance of the state to the subclass of states having well defined classical properties. In particular, a geometric measur…
(Quantumness in the context of) Resource Theories
Michał Horodecki, Jonathan Oppenheim
We review the basic idea behind resource theories, where we quantify quantum resources by specifying a restricted class of operations. This divides the state space into various set…
Quantifying Contextuality
A. Grudka, K. Horodecki, M. Horodecki +5
Contextuality is central to both the foundations of quantum theory and to the novel information processing tasks. Although it was recognized before Bell's nonlocality, despite some…
Decoherence-Free Communication over Multiaccess Quantum Channels
Maciej Demianowicz
In this paper we consider decoherence-free communication over multiple access and -user quantum channels. First, we concentrate on a hermitian unitary noise model for a two-…
Quantum-correlation breaking channels, broadcasting scenarios, and finite Markov chains
J. K. Korbicz, P. Horodecki, R. Horodecki
One of the classical results concerning quantum channels is the characterization of entanglement-breaking channels [M. Horodecki et al., Rev. Math. Phys 15, 629 (2003)]. We address…
Local random quantum circuits are approximate polynomial-designs
Fernando G. S. L. Brandao, Aram W. Harrow, Michal Horodecki
We prove that local random quantum circuits acting on n qubits composed of O(t^{10} n^2) many nearest neighbor two-qubit gates form an approximate unitary t-design. Previously it w…
