Silicon spin qubits are a promising platform for building scalable quantum computers as they are compatible with the semiconductor manufacturing technologies used to produce today’s computer chips. However, they have an important weakness: silicon spin qubits typically lose accuracy when several qubits are under parallel control. To be useful, quantum computers will need to operate many qubits simultaneously without compromising the accuracy of their operations.

Now, in a study published in Nature Physics, researchers from the RIKEN Center for Emergent Matter Science and collaborators have addressed this challenge by achieving high-fidelity control of multiple sili...

Researchers at the Department of Energy’s Oak Ridge National Laboratory incorporated gallium nitride semiconductors to create a high-efficiency power converter that is more compact, affordable, and efficient.

A power converter is a type of device that manages semiconductor switching and transforms current or voltage, so electricity flows smoothly and safely among equipment, power sources, and users.

Silicon semiconductors are the fundamental building blocks of conventional converters...

With the increase of new technology and artificial intelligence, the demand for efficient and powerful semiconductors continues to grow. Researchers at the University of Minnesota have achieved a new material that will be pivotal in making the next generation of high-power electronics faster, transparent and more efficient. This artificially designed material allows electrons to move faster while remaining transparent to both visible and ultraviolet light, breaking the previous record.

The research, published in S...

For the first time, scientists have managed to create sheets of gold only a single atom layer thick. The material has been termed goldene. According to researchers from Linköping University, Sweden, this has given the gold new properties that can make it suitable for use in applications such as carbon dioxide conversion, hydrogen production, and production of value-added chemicals. Their findings are published in the journal Nature Synthesis.

Scientists have long tried to make single-atom-thick sheets of gold but failed because the metal’s tendency to lump together. But researchers from Linköping University have now succeeded thanks to a hundred-year-old method used by Japanese smiths.
