Plasmon‐Mediated Hybridization of Wannier–Mott and Frenkel Excitons in a Monolayer WS2–J‐Aggregate Hybrid System

open access: yesphysica status solidi (RRL) – Rapid Research Letters, EarlyView.
We present a tunable planar plasmonic platform for room temperature hybridization of Wannier–Mott excitons in monolayer WS2 and Frenkel excitons in molecular J‐aggregates. Simultaneous strong coupling to surface plasmon polaritons is revealed by angle‐dependent spectroscopic ellipsometry.

Statistical Complexity of Quantum Learning

open access: yesAdvanced Quantum Technologies, EarlyView.
The statistical performance of quantum learning is investigated as a function of the number of training data N$N$, and of the number of copies available for each quantum state in the training and testing data sets, respectively S$S$ and V$V$. Indeed, the biggest difference in quantum learning comes from the destructive nature of quantum measurements ...

Proposal for a Bose–Einstein Condensate Based Test of Born's Rule Using Light–Pulse Atom Interferometry

open access: yesAdvanced Quantum Technologies, EarlyView.
Light–pulse atom interferometry with ultra‐cold quantum gases is proposed and numerically benchmarked as a competitive platform to test the modulo‐square hypothesis of Born's rule. The interferometric protocol utilizes a combination of double Bragg and single Raman diffraction pulses to induce multipath interference in Bose–Einstein condensates and ...

Hybrid Encoder for Discrete and Continuous Variable QKD

open access: yesAdvanced Quantum Technologies, EarlyView.
This work demonstrates a hybrid QKD encoder that bridges the advantages of discrete and continuous variables. Utilizing a self‐compensating iPOGNAC design, the encoder is compatible with space‐based and terrestrial quantum networks. The approach simplifies system complexity, improves stability, and ensures cost‐effective integration, paving the way for
