Researchers develop the world’s fastest two-qubit gate between two single atoms

The two-qubit gate can be reached in 6.9 nanoseconds.

* A research group succeeded in executing the world’s fastest two-qubit gate. * Quantum computers and optical tweezers were used to conduct the research. * It is used an ultrafast laser to manipulate cold atoms.

The world’s fastest two-qubit gate has been executed in 6.5 nanoseconds by a group of researchers at the National Institutes of Natural Sciences. A research group led by graduate student Yeelai Chew, Assistant Professor Sylvain de Léséleuc, and Professor Kenji Ohmori used atoms cooled to almost absolute zero and trapped in optical tweezers separated by a micron. By manipulating the atoms with special laser light for 10 picoseconds, they executed the world’s fastest two-qubit gate.

Single-cell-resolved differentiation of human induced pluripotent stem cells into pancreatic duct-like organoids on a microwell chip

Circa 2021 immortality of the pancreas by inducing pluripotent cells of the pancreas.

A microwell chip facilitates the single-cell characterization of the differentiation of aggregates of human induced pluripotent stem cells into pancreatic duct-like organoids and the discovery of secreted markers of pancreatic carcinogenesis.

Coin-sized wearable biosensing platform for digital health

A team of researchers in the Faculty of Engineering of The University of Hong Kong (HKU) has developed a coin-sized system that can read weak electrochemical signals and can be used for personalized health monitoring and the measurement of such conditions as diabetes, cardiovascular diseases and mental health. The discovery was featured on the cover of Analytical Chemistry.

The PERfECT System—an acronym for Personalized Electronic Reader for Electrochemical Transistors—is the world’s smallest system of its kind, measuring 1.5 cm x 1.5 cm x 0.2 cm and weighing only 0.4 gram. It is easily wearable, for instance integrated with a smartwatch or as a patch, to allow for continuous monitoring of biosignals such as glucose levels and antibody concentrations in blood and even sweat.

“Our wearable system is tiny, soft and imperceptible to wearers, and it can do continuous monitoring of our body condition. These features mean it has the potential to revolutionize health care technology,” said Dr. Shiming Zhang of the Department of Electrical and Electronic Engineering, who leads the HKU WISE (wearable, intelligent and ) Research Group to develop the system.

New quantum whirlpools with tetrahedral symmetries discovered in a superfluid

An international collaboration of scientists has created and observed an entirely new class of vortices—the whirling masses of fluid or air.

Led by researchers from Amherst College in the U.S. and the University of East Anglia and Lancaster University in the U.K., their new paper details the first laboratory studies of these “exotic” whirlpools in an ultracold gas of atoms at temperatures as low as tens of billionths of a degree above absolute zero.

The discovery, announced this week in the journal Nature Communications, may have exciting future implications for implementations of quantum information and computing.

Intel shares 48 benchmarks to show its Arc A750 can compete with an RTX 3060

A battle for mainstream GPUs could start later this year.

Intel has released 48 benchmarks that show its upcoming Arc A750 GPU should be able to trade blows with Nvidia’s RTX 3,060 running modern games. While Intel set its expectations low for its Arc GPUs last month, the company has now tested its A750 directly against the RTX 3,060 across 42 DirectX 12 titles and six Vulkan games.

The results look promising for what will likely be Intel’s mainstream GPU later this year. Intel has tested the A750 against popular games like Fortnite, Control, and Call of Duty: Warzone, instead of the cherry picked handful of benchmarks the company released last month.

“These are all titles that we picked because they’re popular,” explains Intel fellow Tom Petersen, in Intel’s benchmark video. “Either reviewers are using them or they’re high on the Steam survey, or new and exciting. These are not cherry picked titles.”

Human-machine interfaces work underwater, generate their own power

Wearable human-machine interface devices, HMIs, can be used to control machines, computers, music players, and other systems. A challenge for conventional HMIs is the presence of sweat on human skin.

In Applied Physics Reviews, scientists at UCLA describe their development of a type of HMI that is stretchable, inexpensive, and waterproof. The device is based on a soft magnetoelastic sensor array that converts mechanical pressure from the press of a finger into an .

The device involves two main components. The first component is a layer that translates mechanical movement to a magnetic response. It consists of a set of micromagnets in a porous silicone matrix that can convert the gentle fingertip pressure into a magnetic field variation.

Researchers discover unique material design for brain-like computations

Over the past few decades, computers have seen dramatic progress in processing power; however, even the most advanced computers are relatively rudimentary in comparison with the complexities and capabilities of the human brain.

Researchers at the U.S. Army Combat Capabilities Development Command’s Army Research Laboratory say this may be changing as they endeavor to design computers inspired by the human brain’s neural structure.

As part of a collaboration with Lehigh University, Army researchers have identified a design strategy for the development of neuromorphic materials.

Synthetic Data Generation for Computer Vision in Blender

Alex Martinelli writes:

This entry gives an introduction to and how you can use it via Blender to train performant and robust vision models. I provide the code and node-trees for a demonstrative visual classification scenario from the fashion domain. You’ll then be able to generate a technically infinite amount of images for your use-case.
