A Thermodynamic SU(1,1) Witness Framework for Double-Quantum NMR Signals in Neural Tissue

Christian Kerskens·Apr 8, 2026

Entanglement criteria based on variances or Fisher information are well developed for compact collective spin algebras, but their extension to non-compact dynamical sectors is less straightforward. In particular, double-quantum (DQ) observables assoc...

Fermionic entanglement and quantum correlation measures in molecules

J. Garcia, J. A. Cianciulli, R. Rossignoli·Apr 8, 2026

We analyze fermionic entanglement and correlation measures in the ground and the low temperature thermal state of the water molecule as a function of the internuclear distance in the context of the full configuration interaction approach. The aim is ...

On Lorentzian symmetries of quantum information

James Fullwood, Vlatko Vedral, Edgar Guzmán-González·Apr 8, 2026

A foundational result in relativistic quantum information theory due to Peres, Scudo, and Terno, is that von Neumann entropy is not Lorentz invariant. Motivated by the "It from Qubit" paradigm, here we show that Lorentzian symmetries of quantum infor...

Comment on "Quantum theory based on real numbers cannot be experimentally falsified": On the compatibility of physical principles with information theory for fermions

Fatemeh Moradi Kalarde, Xiangling Xu, Marc-Olivier Renou·Apr 8, 2026

The manuscript [arXiv:2603.19208] proposes a physically motivated postulate to select the appropriate formulation of quantum theory over real Hilbert spaces, ruling out the theory considered in [Nature 600, 625-629 (2021)] in favour of the alternativ...

Beyond the Mean: Modelling Annotation Distributions in Continuous Affect Prediction

Kosmas Pinitas, Ilias Maglogiannis·Apr 8, 2026

Emotion annotation is inherently subjective and cognitively demanding, producing signals that reflect diverse perceptions across annotators rather than a single ground truth. In continuous affect prediction, this variability is typically collapsed in...

Quantum coherent transceivers toward Holevo-limited communications

Volkan Gurses, Suraj Samaga, Elianna Kondylis +1 more·Apr 8, 2026

The Holevo limit bounds the channel capacity of a communication channel in which information is encoded in quantum states in a Hilbert space at the transmitter and decoded using quantum measurements at the receiver. Saturating the Holevo limit requir...

Complete coherent control of spin qubits in self-assembled InAs quantum dots under oblique magnetic fields

I. Samaras, K. Barr, C. Schneider +2 more·Apr 8, 2026

We demonstrate complete coherent control of a single spin qubit confined in a self-assembled InAs negatively charged quantum dot subjected to an Oblique magnetic field, and directly compare this regime with the conventional Voigt geometry. In the Obl...
