Adiabatic state preparation (ASP) represents an efficient way of generating correlated wave functions on quantum computers for subsequent quantum simulation. Here, the author discusses recent work that numerically studied the performance of ASP on strongly correlated molecules and presented several approaches of improving the quality of prepared ground state wave functions.

Arterial Stiffness and Markers of Atrial Myopathy.
Ann Noninvasive Electrocardiol
March 2025
Department of Clinical Sciences, Malmö, Lund University, Malmö, Sweden.
Background: Arterial stiffness, measured using carotid-femoral pulse wave velocity (c-f PWV) and heart rate-corrected augmentation index (Aix75), is associated with cardiovascular disease, and in some studies incident atrial fibrillation (AF). In this cross-sectional study, we aimed to investigate whether arterial stiffness is associated with markers of atrial myopathy, which refers to structural and electrical changes in the atria that indicate increased AF risk.
Methods: We included 1050 participants (age 57 ± 4.
Projector-Based Quantum Embedding Study of Iron Complexes.
J Comput Chem
January 2025
Physical and Computational Sciences Directorate, Pacific Northwest National Laboratory, Richland, Washington, USA.
Projection-based embedding theory (PBET) is used to calculate and assess the challenging spin-crossover energies for a selection of small Fe-containing systems by embedding the metal center into the frozen potential of the ligands. MP2, CCSD, and CCSD(T) are embedded in potentials from the SCAN and rSCAN functionals and compared with the canonical values for the constituent methods and previously reported reference values. Considering the PBET calculations as a correction for the underlying DFT, the embedding calculations are able to provided improvement for most cases.

Department of Cardiology, The First Affiliated Hospital of Nanjing Medical University, Nanjing, China.
Background: Left bundle branch pacing (LBBP) emerged as a novel physiological pacing modality that improves clinical outcomes. This study aimed to explore the impact of LBBP on QRS wave amplitude (RWA).
Methods: This prospective observational study included patients with complete left bundle branch block (CLBBB) and cardiac resynchronization therapy (CRT) indication, as well as patients with QRSd < 120 ms and pacemaker indication.
Experimental Realization of On-Chip Surface Acoustic Wave Metasurfaces at Sub-GHz.

Metasurfaces, consisting of subwavelength-thickness units with different wave responses, provide an innovative possible method to manipulate elastic and acoustic waves efficiently. The application of metasurfaces to manipulate on-chip surface acoustic wave (SAW) at sub-GHz frequencies requires further exploration since their wave functions are highly demanded in nanoelectromechanical systems (NEMS), sensing, communications, microfluid control and quantum processing. Here, the experimental realization of on-chip SAW metasurfaces is reported, consisting of gradient submicron niobium (Nb) rectangular pillars positioned on a 128°Y-cut lithium niobate (LiNbO) substrate that operate at hundreds of megahertz.

The structural disorder of the black butterfly assists in capturing sunlight across a wider spectral and angular range, injecting infinite vitality for omnidirectional and stimuli-responsive wave-absorbing materials. Here, the disordered micro-pores responding to terahertz (THz) waves through electromagnetic simulations, and then prepared via ice templating technology are analyzed and optimized. The customized disordered aerogel makes possible perfect terahertz response property with incidence-angle-insensitive and ultra-broadband.
