Demonstrating real-time and low-latency quantum error correction with superconducting qubits
Laura Caune, Luka Skoric, Nick S. Blunt +22
Quantum error correction (QEC) will be essential to achieve the accuracy needed for quantum computers to realise their full potential. The field has seen promising progress with de…
Coexistency on Hilbert space effect algebras and a characterisation of its symmetry transformations
Gyorgy Pal Geher, Peter Semrl
The Hilbert space effect algebra is a fundamental mathematical structure which is used to describe unsharp quantum measurements in Ludwig's formulation of quantum mechanics. Each e…
Entanglement entropy of two disjoint intervals separated by one spin in a chain of free fermion
L. Brightmore, G. P. Geher, A. R. Its +4
We calculate the entanglement entropy of a non-contiguous subsystem of a chain of free fermions. The starting point is a formula suggested by Jin and Korepin, \texttt{arXiv:1104.10…
On isometric embeddings of Wasserstein spaces -- the discrete case
György Pál Gehér, Tamás Titkos, Dániel Virosztek
The aim of this short paper is to offer a complete characterization of all (not necessarily surjective) isometric embeddings of the Wasserstein space ,…
Bilateral weighted shift operators similar to normal operators
György Pál Gehér
We prove that an injective, not necessarily bounded weighted bilateral shift operator on is similar to a normal operator if and only if it is similar to a scal…
