On precanonical quantization of gravity in spin connection variables
I. V. Kanatchikov
The basics of precanonical quantization and its relation to the functional Schrödinger picture in QFT are briefly outlined. The approach is applied to quantization of Einstein's gr…
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…
Cosmological parameters from the thermodynamic model of gravity
Merab Gogberashvili, Igor Kanatchikov
Within our recent thermodynamic model of gravity the dark energy is identified with the energy of collective gravitational interactions of all particles in the universe, which is m…
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…
