Local qubit invariants on quantum computer
Szilárd Szalay, Szilárd Szalay, Frédéric Holweck +1
We present two general methods to implement quantum circuits for the direct measuring of local unitary invariants on quantum computers. We work these out for important three-qubit…
The three kinds of three-qubit entanglement
Szilárd Szalay
We construct an important missing piece in the entanglement theory of pure three-qubit states, which is a polynomial measure of W-entanglement, working in parallel to the three-tan…
Dicke subsystems are entangled
Szilárd Szalay, Péter Nyári
We show that all reduced states of nonproduct symmetric Dicke states of arbitrary number of qudits are genuinely multipartite entangled, and of nonpositive partial transpose with r…
Alternatives of entanglement depth and metrological entanglement criteria
Szilárd Szalay, Géza Tóth
We work out the general theory of one-parameter families of partial entanglement properties and the resulting entanglement depth-like quantities. Special cases of these are the dep…
Noncommuting common causes revisited
Gábor Hofer-Szabó, Szilárd Szalay
In this paper, we revisit the concept of noncommuting common causes; refute two objections raised against them, the triviality objection and the lack of causal explanatory force; a…
