Researchers from The University of Osaka, SEC, and Juntendo University have developed quantum multi-programming auto mode, a function that automatically runs quantum programs from different users in parallel. Implemented in OQTOPUS and launched on QIQB’s quantum computer cloud service, the system reduces idle qubit resources, improves throughput, and may help ease congestion in quantum cloud computing.

With Texas quickly becoming a global hub for quantum innovation, Gov. Greg Abbott has appointed Jeff Prevost, PhD, executive director of UT San Antonio’s Open Cloud Institute, to the newly established Texas Quantum Initiative Advisory Committee. 

The DIVINE cohort brings together clinical data from 5,813 patients hospitalised with COVID-19 during the first four waves of the pandemic and makes it available to the scientific community through an open, accessible and reusable resource. Published in Scientific Data, this multicentre database has already contributed to several studies and aims to support further research into the clinical progression of COVID-19, associated risk factors and the development of predictive models.

Charge noise arising from two-level fluctuators is considered to play a key role in causing qubit frequency shifts in silicon spin qubits, resulting in deteriorated gate fidelity. Higher temperatures can improve gate fidelity, but the microscopic origins of this effect and of qubit frequency shift have not yet been established. Now, using statistical simulations, researchers have clarified the parameter regimes under which gate fidelity can be improved and the potential origin of qubit frequency shifts.

How do waves spread, stall, or pile up in materials that are both messy and “open”—leaking energy to their surroundings? Researchers at the Institute of Physics, Chinese Academy of Sciences have derived a compact mathematical rule, the universal Thouless relations (UTRs), that links two seemingly separate things: how densely energy levels populate the spectrum, and how strongly waves grow or decay across the system. The relations work for a broad family of one-dimensional disordered, non-Hermitian models, predict the boundary between two kinds of wave trapping without heavy computation, and uncover a new type of “half-localized, half-fractal” critical state with no counterpart in ordinary closed systems.

POSTECH Professor Sunmin Ryu’s team analyzes structural inhomogeneity in large-area thin films using interferometric SHG imaging.

Future math teachers may be the key to bringing data science into high‑school classrooms, and curriculum designed by researchers from Iowa State University and the University of Northern Iowa is helping pre-service teachers build their data‑science skills by tapping into the math they already know.
