An architecture for sub-picowatt logic computing based on self-biased molybdenum disulfide transistors

Posted by in categories: computing, electronics

The continuous improvement of circuits and electronic components is vital for the development of new technologies with enhanced capabilities and unique characteristics. In recent years, most electronics engineers have been specifically focusing on reducing the size of transistors, while retaining a low power consumption.

Researchers at University of Science and Technology Beijing recently introduced a new pseudo-CMOS architecture based on self-biased molybdenum disulfide transistors. This architecture, outlined in Nature Electronics, could be used to create highly performing inverters, gate circuits, and other device components.

“The development of integrated circuits (ICs) for efficient computing with low power is a global hot topic and a focus of international competition in cutting-edge fields,” Zheng Zhang, co-author of the paper, told Tech Xplore.

Elon Musk shares update on Neuralink’s first human patient

Posted by in categories: biotech/medical, computing, Elon Musk, neuroscience

Elon Musk shared an update on Neuralink’s first human patient and their experience with the N1 chip.

The first human Neuralink patient seems to have made a full recovery with no ill effects and is able to control the mouse around the screen just by thinking, said Elon Musk during an apparent on X Spaces.

Musk added that Neuralink continuously observes the patient’s ability to use the N1 brain implant. The patient is currently tasked to click on the mouse button as often as possible.

Neuralink’s first human patient able to control mouse through thinking, Musk says

Feb 20 (Reuters) — The first human patient implanted with a brain-chip from Neuralink appears to have fully recovered and is able to control a computer mouse using their thoughts, the startup’s founder Elon Musk said late on Monday.

“Progress is good, and the patient seems to have made a full recovery, with no ill effects that we are aware of. Patient is able to move a mouse around the screen by just thinking,” Musk said in a Spaces event on social media platform X.

Musk said Neuralink was now trying to get as many mouse button clicks as possible from the patient.

Quantum computing engineers perform multiple control methods in just one atom

Posted by in categories: computing, particle physics, quantum physics

Quantum computing engineers at UNSW Sydney have shown they can encode quantum information—the special data in a quantum computer—in four unique ways within a single atom, inside a silicon chip.

The feat could alleviate some of the challenges in operating tens of millions of quantum computing units in just a few square millimeters of a silicon quantum computer chip.

In a paper published in Nature Communications, the engineers describe how they used the 16 quantum ‘states’ of an antimony atom to encode quantum information.

Billions Start Flowing to Chip Makers for New U.S. Factories

Posted by in categories: computing, government

The U.S. government is giving chip maker GlobalFoundries $1.5 billion in grants to build and expand facilities in New York and Vermont, the first major award in a program that aims to reinvigorate domestic chip production.

The award from the Commerce Department kicks off what is expected to be a series of cash injections into semiconductor manufacturing projects in Arizona, Texas, New York and Ohio in the coming weeks. Chip makers Intel, Taiwan Semiconductor Manufacturing, Samsung Electronics and Micron Technology have all submitted applications for the government to cover a portion of the billions of dollars it costs to build cutting-edge factories.

MIT develops tamper-proof ID tag for cheaper and secure authentication

Posted by in categories: computing, particle physics, security

RFID tags are commonly used to verify the authenticity of products, but they have some drawbacks. They are relatively large, expensive, and vulnerable to counterfeiting. A team of MIT engineers has developed a new type of ID tag that overcomes these limitations by using terahertz waves, which are smaller and faster than radio waves.

The new tag is a cryptographic chip several times smaller and cheaper than RFID tags. It also offers improved security, using the unique pattern of metal particles in the glue that attaches the tag to the item as a fingerprint. This way, the authentication system will detect tampering if someone tries to peel off the tag and stick it to a fake item.

Quantinuum-led Scientists’ Non-Abelian Topological Order Study Published in Nature

Posted by in categories: computing, quantum physics

Last year, a Quantinuum-led team of scientists announced that they were able to realize and control a state of matter known as non-Abelian topological order within a quantum processor. The team published their results in the pre-print server ArXiv, outlining how they accomplished what many experts considered a far-off advance — if possible at all – and what the scientists hoped could be an advance toward revolutionizing the way we approach quantum computing.

That advance has now been officially peer reviewed in Nature, marking another important step in the scientific process – and maybe even a significant step in the quest for fault-tolerant quantum computers, a quantum device that could handle operations with unprecedented accuracy and efficiency.

“Our key finding is that non-Abelian topological orders can experimentally be prepared with high fidelities on par with Abelian states like the surface code,” the team writes. “Non-Abelian states are among the most intricately entangled quantum states theoretically known to exist, and carry promise for new types of quantum information processing. Their realization evidences the rapid development of quantum devices and opens several new questions.”
