Silicon nanoelectronic device hosts ‘flip-flop’ qubit

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

A team led by Professor Andrea Morello has just demonstrated the operation of a new type of quantum bit, called ‘flip-flop’ qubit, which combines the exquisite quantum properties of single atoms, with easy controllability using electric signals, just as those used in ordinary computer chips.

“Sometimes new qubits, or new modes of operations, are discovered by lucky accident. But this one was completely by design,” says Prof. Morello. “Our group has had excellent qubits for a decade, but we wanted something that could be controlled electrically, for maximum ease of operation. So we had to invent something completely new.”

Prof. Morello’s group was the first in the world to demonstrate that using the spin of an electron as well as the nuclear spin of a single phosphorus atom in silicon could be used as ‘qubits’ – units of information that are used to make quantum computing calculations. He explains that while both qubits perform exceptionally well on their own, they require oscillating magnetic fields for their operation.

‘Magic’ solvent creates stronger thin films

Posted by in categories: chemistry, engineering

A new all-dry polymerization technique uses reactive vapors to create thin films with enhanced properties, such as mechanical strength, kinetics and morphology. The synthesis process is gentler on the environment than traditional high-temperature or solution-based manufacturing and could lead to improved polymer coatings for microelectronics, advanced batteries and therapeutics.

“This scalable technique of initiated chemical vapor deposition polymerization allows us to make new materials, without redesigning or revamping the whole chemistry. We just simply add an ‘active’ solvent,” said Rong Yang, assistant professor in the Smith School of Chemical and Biomolecular Engineering in Cornell Engineering. “It’s a little bit like a Lego. You team up with a new connecting piece. There’s a ton you can build now that you couldn’t do before.”

Largest galaxy in the universe stunning new composite image

Posted by in category: space

A spectacular new photo has been released showing the record-holder for largest galaxy in the universe.

NGC 6872, also known as the Condor Galaxy, stretches 522,000 light years from tip to tip. The Milky Way is approximately 100,000 light years across.

The galaxy is visible in the southern skies as part of the Pavo constellation, and is 212 million light-years from Earth.

RNA’s ‘joints’ play key role in our gene expression, scientists find

Posted by in categories: biotech/medical, evolution, life extension, neuroscience

University of Chicago scientists have discovered a new wrinkle in our understanding of how our genes work. The team, led by Chuan He, the UChicago John T. Wilson Distinguished Service Professor of Chemistry, Biochemistry and Molecular Biology, shed light on a longstanding puzzle involved in a common way our genes are modified that is known as RNA methylation.

Published Jan. 27 in Science, the finding could have implications for for disease, as well as our picture of gene expression, development, and evolution.

For more than a decade, Chuan He’s laboratory has been focused on trying to unravel the puzzle of a phenomenon called RNA methylation, which we are increasingly understanding plays a key role in our bodies and lives—everything from cancer to PTSD to aging.

Has the ‘missing’ 70% of the universe FINALLY been found? Scientists find first evidence that black holes are the source of mysterious dark energy

Posted by in category: cosmology

Source of Dark Energy is black holes combined with Einstein’s gravity — experts Result potentially means nothing new has to be added to our picture of Universe It makes up most of the universe, yet hardly anything is known about the so-called Dark Energy that envelopes us. The unusual ‘something’ – one of the great mysteries of cosmology – is believed to be an unknown force that is pushing things apart more strongly than gravity and causing the universe’s expansion to accelerate.

Generative AI Unlocking Floodgates to Solve Data Scarcity

Posted by in categories: privacy, robotics/AI, transportation

The concept of synthetic data is almost too good to be true – it can mimic the distinctive properties of a dataset while dodging a number of issues that afflict data. There are zero data privacy concerns around synthetic data since it is artificially generated and isn’t related to real-world persons. It can be manufactured on demand and in the volumes required. In other words, synthetic data is a boon in a world eternally thirsty for data.

And the hectic space of generative AI is offering a helping hand in the easy generation of synthetic data.

The concept of synthetic data has been around for decades until the autonomous vehicle (AV) industry started using it commercially in the mid-2010s. But for how important an issue it resolves, creating synthetic data brings a myriad of complications along with it.

US startup introduces DC-to-DC solar EV charger

Posted by in category: energy

With most EV chargers, which are AC-to-DC, there is lost energy and a longer charging time. But with DC to DC, according to Enteligent, the DC-to-DC charging results in up to 25% energy savings because the power does not have to be converted.


From pv magazine USA

Enteligent unveiled its DC-to-DC-solar hybrid bi-directional EV charger this week at Intersolar North America. Powered by the sun, the EV charger can supply 25 kW of fast DC charging, charging three times faster than AC Level 2 EV chargers, the company reports.
