Semiconductor qubits scale in two dimensions — ScienceDaily

The heart of any computer, its central processing unit, is built using semiconductor technology, which is capable of putting billions of transistors onto a single chip. Now, researchers from the group of Menno Veldhorst at QuTech, a collaboration between TU Delft and TNO, have shown that this technology can be used to build a two-dimensional array of qubits to function as a quantum processor. Their work, a crucial milestone for scalable quantum technology, was published today in Nature.

Quantum computers have the potential to solve problems that are impossible to address with classical computers. Whereas current quantum devices hold tens of qubits — the basic building block of quantum technology — a future universal quantum computer capable of running any quantum algorithm will likely consist of millions to billions of qubits. Quantum dot qubits hold the promise to be a scalable approach as they can be defined using standard

Huawei Launches the Smart Classroom Solution

— based on HUAWEI IdeaHub Board and the education cloud platform

SHENZHEN, China, March 27, 2021 /PRNewswire/ — At the Education Session of the Huawei Industrial Digital Transformation Conference, Huawei invited renowned experts from across the industry to discuss the innovative application of ICT in modern education under the theme of “ICT Transforms Education and Innovates Smart Classrooms”, and launched the Smart Classroom Solution, which is based on HUAWEI IdeaHub Board and the education cloud platform.

The managers and teachers at numerous schools and educational institutions have prioritized the same long-term challenges, such as the lack of interactive teaching methods, unbalanced allocation of resources, and low management efficiency due to scattered schools. At this conference, Mr. Xu Jun, Vice President of Global Government Business Unit, Enterprise Business Group of Huawei, introduced the Huawei Smart Classroom Solution, which focuses on students and combines both online and offline methods to

German Physicists Say Traversable Wormholes Possible

German physicists explore the possibility of tunnels in spacetime.

Wormholes play a key role in many science fiction films — often as a shortcut between two distant points in space. In physics, however, these tunnels in spacetime have remained purely hypothetical. An international team led by Dr. Jose Luis Blázquez-Salcedo of the University of Oldenburg has now presented a new theoretical model in the science journal Physical Review Letters that makes microscopic wormholes seem less far-fetched than in previous theories.

Wormholes, like black holes, appear in the equations of Albert Einstein’s general theory of relativity, published in 1916. An important postulate of Einstein’s theory is that the universe has four dimensions — three spatial dimensions and time as the fourth dimension. Together they form what is known as spacetime, and spacetime can be stretched and curved by massive objects such as stars, much as a rubber sheet would be curved

High school football games changed following positive COVID-19 tests

FRESNO, California (KSEE) – Fresno County is closely monitoring high school contact sports when it comes to COVID-19 transmission, testing to find players who have the virus but do not show symptoms. It has forced some high school football games to be changed due to positive tests.

Clovis North was scheduled to play Clovis High School this Friday, but those plans have changed. Clovis High will be playing Madera High school instead.

Athletic Director for Madera Unified School District Marty Bitter said they test also their student-athletes for COVID-19.

“We tested on Monday,” said Bitter. We did a PCR test and what we do with that is they contact trace 48 hours prior if you do have a positive.”

Bitter said Madera High School did not have any of their student-athletes test positive this time around.

“Clovis North is where they had a little bit of the outbreak,” said Bitter.
