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 ...

Open and Closed Loop Approaches for Energy Efficient Quantum Optimal Control

Advanced Quantum Technologies, EarlyView.
Concepts from quantum thermodynamics and optimal control are blended to derive a theoretical framework to quantify and minimize the energetic cost of a pulse for unitary synthesis. Two complementary techniques (based on GRAPE and Reinforce‐DRL) are implemented as open‐source software that co‐optimizes the fidelity and energetic cost within quantum ...

Resolving the Nanostructure of Carbon Nitride‐Supported Single‐Atom Catalysts

Small, EarlyView.
This study investigates the nanostructure of Ni‐based single‐atom catalysts supported on carbon nitride. By combining synthesis, advanced characterizations, and DFT calculations, the study reveals a new architecture for the nickel active sites, challenging previous models.

Organic Reactivity Matters for the Emergence of Life: Kinetic Barriers and Molecular Diversity Are Suggested as Crucial Factors by Emerging Autonomous System Models

ChemSystemsChem, EarlyView.
Self‐organisation may result from organic systems fed with free energy provided that reactivity becomes a determining factor. The propensity of carbon to form covalent bonds can give rise to kinetically stable thermodynamically activated compounds possibly undergoing non‐linear kinetic processes.
