Was Schrödinger ever a determinist?
Flavio Del Santo, Nicolas Gisin
Erwin Schrödinger is often portrayed as a reactionary who resisted the indeterminism introduced by quantum mechanics, but on closer inspection his views on determinism prove to be…
Bipartite Bound Information Exists
Jef Pauwels, Nicolas Gisin, Renato Renner
Bound entanglement is an extreme irreversibility of quantum theory: certain states cost entanglement to create, yet no singlet can be distilled from them. Twenty-five years ago, Gi…
Uncountably many inequivalent maximally entangled measurements for two qutrits
Elna Svegborn, Jef Pauwels, Nicolas Gisin +1
Every two-qubit measurement basis composed of maximally entangled eigenstates can be transformed into the Bell basis via local unitary operations. For higher dimensions, in contras…
Tunable Families of Multiqubit Elegant Joint Measurements
Jef Pauwels, Nicolas Gisin
We give a closed-form construction of the -qubit Elegant Joint Measurement (EJM) proposed in [PRL \textbf{136}, 190201 (2026)] and show that it is part of a tunable family of me…
Experimental genuine quantum nonlocality in the triangle network
Ning-Ning Wang, Chao Zhang, Huan Cao +8
In the last decade, it was understood that quantum networks involving several independent sources of entanglement which are distributed and measured by several parties allowed for…
The Multiqubit Elegant Joint Measurement
Jef Pauwels, Nicolas Gisin
The Elegant Joint Measurement (EJM) is a highly symmetric, partially entangled two-qubit measurement whose local marginals form a regular tetrahedron on the Bloch sphere and which…
