Digital quantum simulation of cosmological particle creation with IBM quantum computers [PDF]
We use digital quantum computing to simulate the creation of particles in a dynamic spacetime. We consider a system consisting of a minimally coupled massive quantum scalar field in a spacetime undergoing homogeneous and isotropic expansion ...

Effect of precursor powder uniformity on structure and electrical properties of gadolinium-doped cerium oxide ceramics [PDF]
The effects of precursor powder uniformity on structure and electrical properties of Gd-doped CeO2 (GDC) electrolytes were studied. The as-synthesized GDCx powders (x = 5, 10 and 15 at.%) were calcined at 600 and 1200°C and combined in mass ratios of 100:

Dynamical Collective Excitations and Entanglement of Two Strongly Correlated Rydberg Superatoms
Based on the dipole blockade effect and with the aid of the superatom (SA) model, we propose a scheme to investigate the correlated evolution of two Rydberg sub-superatoms (SSAs), formed by two spatially separated atomic Rydberg sub-ensembles but in the ...

Benchmarking of force fields to characterize the intrinsically disordered R2-FUS-LC region
Intrinsically Disordered Proteins (IDPs) play crucial roles in numerous diseases like Alzheimer's and ALS by forming irreversible amyloid fibrils. The effectiveness of force fields (FFs) developed for globular proteins and their modified versions for ...

State-dependent error bound for digital quantum simulation of driven systems [PDF]
Digital quantum simulation is a promising application of quantum computers, where quantum dynamics is simulated by using quantum gate operations. Many techniques for decomposing a time-evolution operator of quantum dynamics into simulatable quantum gate operations have been proposed, while these methods cause some errors.
