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.

Researchers at Yokohama City University, Japan, have uncovered evidence that the Y chromosome gene UTY still retains regulatory activity in human embryonic stem cells, offering a rare glimpse into what may represent an evolutionary transitional state of the human Y chromosome.

Seoul National University College of Engineering announced that a research team led by Prof. Jungwon Park of the Department of Chemical and Biological Engineering, in collaboration with research teams led by Prof. Thomas F. Jaramillo of the Department of Chemical Engineering at Stanford University and SLAC National Accelerator Laboratory, Prof. Matteo Cargnello of the Department of Chemical Engineering at Stanford University, and Dr. Frank Abild-Pedersen at SLAC National Accelerator Laboratory has developed a commercially viable hydrogen production technology by synthesizing uniform cluster catalysts controlled at the atomic level.

The development of atomic level molecular editing methods for metal clusters is an important avenue in synthetic chemistry that can expand the structure diversity and functionality of these compounds. In a new study, researchers have developed a novel, highly selective asymmetric synthesis approach to develop chiral optical metal clusters with photoluminescence. This approach can contribute to the development of chiral luminescent nanomaterials, benefiting several industries.
