Theoretical and Electrochemical Evaluation of Cannabis Sativa L. Extracts as Corrosion Inhibitors for Mild Steel in Acidic Medium

ChemistryOpen, EarlyView.
This study examines ethanol (EET), hexane (EHX), and dichloromethane (EDM) extracts of C. sativa L. as eco‐friendly corrosion inhibitors for mild steel in 1 M HCl. At 0.8 g/L, inhibition efficiencies of 90 %, 88 %, and 81 % are observed. Adsorption follows the Langmuir isotherm, supported by DFT, Monte Carlo, and molecular dynamics simulations ...

Elucidating the Three‐Dimensional Structure of Piracetam through Rotational Spectroscopy

ChemistryOpen, EarlyView.
Neutral molecules of the nootropic drug piracetam are generated by laser ablation and structurally characterized by microwave spectroscopy. Two conformers differing in the exo/endo configuration of the pyrrolidine ring are detected, with exo being the predominant form.

Nuclear Physics in the Era of Quantum Computing and Quantum Machine Learning

Advanced Quantum Technologies, EarlyView.
The use of QML in the realm of nuclear physics at low energy is almost nonexistent. Three examples of the use of quantum computing and quantum machine in nuclear physics are presented: the determination of the phase/shape in nuclear models, the calculation of the ground state energy, and the identification of particles in nuclear physics experiments ...

Toward Useful Quantum Kernels

Advanced Quantum Technologies, EarlyView.
The hybrid approach to Quantum Supervised Machine Learning is compatible with Noisy Intermediate Scale Quantum (NISQ) devices but hardly useful. Pure quantum kernels requiring fault‐tolerant quantum computers are more promising. Examples are kernels computed by means of the Quantum Fourier Transform (QFT) and kernels defined via the calculation of ...

Simulation of a Three‐Nucleons System Transition on Quantum Circuits

Advanced Quantum Technologies, EarlyView.
A general procedure is presented to calculate the transition probability for two nuclear states and a transition operator. The ground state is approximated through the variational quantum eigensolver and the first excited one using more sophisticated variational algorithms.

Robust Weak Measurements with Certified Single Photons

Advanced Quantum Technologies, EarlyView.
Weak values are usually extracted by statistical means, but with robust weak measurements they can be extracted by a single detection event with reasonable uncertainty. Here, robust weak measurements are experimentally implemented on certified single photons.

Joint Wire Cutting with Non‐Maximally Entangled States

Advanced Quantum Technologies, EarlyView.
Wire cutting decomposes large quantum circuits into smaller subcircuits by severing connecting wires, enabling execution on multiple distributed devices. This study employs non‐maximally entangled (NME) states in joint wire cuts to reduce their overhead.

Efficient Simulation of Open Quantum Systems on NISQ Trapped‐Ion Hardware

Advanced Quantum Technologies, EarlyView.
Open quantum systems exhibit rich dynamics that can be simulated efficiently on quantum computers, allowing us to learn more about their behavior. This work applies a new method to simulate certain open quantum systems on noisy trapped‐ion quantum hardware.

Multi‐Photon Fock State Generation via Selective Single Photon Subtraction in a Cascaded Waveguide QED System

Advanced Quantum Technologies, EarlyView.
This work proposes a photon subtraction scheme, termed ′photon culling′, that enables the selective extraction of a single photon based on its arrival time relative to other photons. This scheme enables the generation of multi‐photon Fock states with high fidelity and modal purity, demonstrating significant potential for quantum metrology applications ...

Disentangling Carrier‐Transport and Interfacial Carrier‐Recombination by Mitigating Na Interstitials for 11.9% Efficient Cd‐Free Cu2ZnSnS4 Solar Cells

Small, EarlyView.
A high‐efficiency Cd‐free CZTS solar cell of 11.9% efficiency is achieved by mitigating the charge‐compensation effect of Na interstitials in the CZTS absorber using device air annealing. The JSC and FF are significantly improved with enhanced electron mobility, hole density, and carrier collection efficiency in the depletion region.
