Microsoft deploys new state of matter in its first quantum computing chip

The achievement comes after the company spent nearly two decades of research in the field, but Microsoft claims that building Majorana 1 required that it create an entirely new state of matter, which it is referring to as a topological state.

Microsoft’s quantum chip employs eight topological qubits using indium arsenide, which is a semiconductor, and aluminum, which is a superconductor.

“The difficulty of developing the right materials to create the exotic particles and their associated topological state of matter is why most quantum efforts have focused on other kinds of qubits,” the company said in a blog Wednesday.

China: World-first dual-loop brain-computer interface unveiled

The US, Europe, and China have all contributed significantly to BCI advancements. Companies like Elon Musk’s Neuralink focus on invasive brain implants, whereas Chinese researchers have made major strides in developing non-invasive and adaptive BCIs.

This latest breakthrough underscores China’s commitment to making BCIs more efficient and user-friendly. By enabling a two-way interaction between brain and machine, the new system takes a significant step toward integrating BCIs into everyday life, from medical rehabilitation to consumer electronics.

The study was published in the journal Nature Electronics.

High-performance sodium-ion cathode paves the way for lithium-ion battery alternative

Tech giant Microsoft unveiled a new computer chip on Wednesday that it says could transform everything from fighting pollution to developing new medicines, joining Google and IBM in arguing that the promise of quantum computing is closer to reality.

The US-made , called Majorana 1, can fit in the palm of a hand but packs a revolutionary design that Microsoft believes will solve one of the biggest challenges in quantum computing—making these super-powerful machines reliable enough for real-world use.

“We took a fresh approach and basically reinvented how quantum computers could work,” said Chetan Nayak, a senior scientist at Microsoft.

Unlocking the secrets of superconductors: New insights into key structure-property connections in cuprates

When superconductors were discovered in 1911, they astounded researchers with their ability to conduct electricity with no resistance. However, they could only do so at temperatures close to absolute zero. But in 1986, scientists discovered that cuprates (a class of copper oxides) were superconductive at a relatively warm −225°F (above liquid nitrogen)—a step toward the ultimate goal of a superconductor that could operate at close to room temperature.

Applications of such a superconductor include compact and portable MRI machines, levitating trains, long-range electrical transmission without power loss, and more resilient quantum bits for quantum computers. Unfortunately, cuprates are a type of ceramic material which makes their application at industrial scales difficult—their brittleness, for example, would pose problems.

However, if researchers could understand what makes them superconduct at such high temperatures, they could recreate such processes in other materials. Despite a great deal of research, though, there is still a lack of consensus on the microscopic mechanism leading to their unusual superconductivity, making it difficult to take advantage of their unusual properties.

Magnetic semiconductor preserves 2D quantum properties in 3D material

There is a big problem with quantum technology—it’s tiny. The distinctive properties that exist at the subatomic scale usually disappear at macroscopic scales, making it difficult to harness their superior sensing and communication capabilities for real-world applications, like optical systems and advanced computing.

Now, however, an international team led by physicists at Penn State and Columbia University has developed a novel approach to maintain special quantum characteristics, even in three-dimensional (3D) materials.

The researchers published their findings in Nature Materials.
