Computational Approaches to Alkaline Anion-Exchange Membranes for Fuel Cell Applications

Membranes, 2022
Anion-exchange membranes (AEMs) are key components in relatively novel technologies such as alkaline exchange-based membrane fuel cells and AEM-based water electrolyzers.

Homodyne-based quantum random number generator at 2.9 Gbps secure against quantum side-information

Nature Communications, 2021
Security analyses for trusted quantum random number generators usually consider only classical side-information. Here, the authors fill this gap by fully characterising the experimental apparatus of a homodyne-based QRNG, assuming that the vacuum ...

Measurement-free preparation of grid states

npj Quantum Information, 2021
Quantum computing potentially offers exponential speed-ups over classical computing for certain tasks. A central, outstanding challenge to making quantum computing practical is to achieve fault tolerance, meaning that computations of any length or size ...

Machine learning aided carrier recovery in continuous-variable quantum key distribution

npj Quantum Information, 2021
The secret key rate of a continuous-variable quantum key distribution (CV-QKD) system is limited by excess noise. A key issue typical to all modern CV-QKD systems implemented with a reference or pilot signal and an independent local oscillator is ...

Macroscopic fluctuation theory [PDF]

, 2015
Stationary non-equilibrium states describe steady flows through macroscopic systems. Although they represent the simplest generalization of equilibrium states, they exhibit a variety of new phenomena. Within a statistical mechanics approach, these states

Violations of Bell Inequalities for Measurements with Macroscopic Uncertainties: What does it Mean to Violate Macroscopic Local Realism? [PDF]

, 2000
We suggest to test the premise of ``macroscopic local realism'' which is sufficient to derive Bell inequalities when measurements of photon number are only accurate to an uncertainty of order $n$ photons, where $n$ is macroscopic.

Variation Analysis of CMOS Technologies Using Surface-Potential MOSFET Model

Journal of Telecommunications and Information Technology, 2023
An analysis of the measured macroscopic withinwafer variations for threshold voltage (Vth) and on-current (Ion) over several technology generations (180 nm, 100 nm and 65 nm) is reported.
