President Trump has signed a $1.2 billion law to boost US quantum tech

Posted by in categories: government, law, quantum physics, supercomputing

This new law was signed just as a partial US government shutdown began.


The new National Quantum Initiative Act will give America a national masterplan for advancing quantum technologies.

The news: The US president just signed into law a bill that commits the government to providing $1.2 billion to fund activities promoting quantum information science over an initial five-year period. The new law, which was signed just as a partial US government shutdown began, will provide a significant boost to research, and to efforts to develop a future quantum workforce in the country.

Cold atoms offer a glimpse of flat physics

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

These days, movies and video games render increasingly realistic 3D images on 2-D screens, giving viewers the illusion of gazing into another world. For many physicists, though, keeping things flat is far more interesting.

One reason is that flat landscapes can unlock new movement patterns in the quantum world of and electrons. For instance, shedding the third dimension enables an entirely new class of particles to emerge—particles that that don’t fit neatly into the two classes, bosons and fermions, provided by nature. These new particles, known as anyons, change in novel ways when they swap places, a feat that could one day power a special breed of quantum computer.

But anyons and the conditions that produce them have been exceedingly hard to spot in experiments. In a pair of papers published this week in Physical Review Letters, JQI Fellow Alexey Gorshkov and several collaborators proposed new ways of studying this unusual flat physics, suggesting that small numbers of constrained atoms could act as stand-ins for the finicky electrons first predicted to exhibit low-dimensional quirks.

Quantum Maxwell’s demon ‘teleports’ entropy out of a qubit

Posted by in categories: computing, law, quantum physics

Researchers from the Moscow Institute of Physics and Technology, ETH Zurich, and Argonne National Laboratory, U.S, have described an extended quantum Maxwell’s demon, a device locally violating the second law of thermodynamics in a system located 1–5 meters away from the demon. The device could find applications in quantum computers and microscopic refrigerators cooling down tiny objects with pinpoint accuracy. The research was published Dec. 4 in Physical Review B.

The second law says that the entropy — that is, the degree of disorder or randomness — of an isolated system never decreases.

“Our demon causes a device called a qubit to transition into a more orderly state,” explained the study’s lead author Andrey Lebedev of MIPT and ETH Zurich. “Importantly, the demon does not alter the qubit’s energy and acts over a distance that is huge for quantum mechanics.”

Researchers demonstrate teleportation using on-demand photons from quantum dots

Posted by in categories: cybercrime/malcode, quantum physics

A team of researchers from Austria, Italy and Sweden has successfully demonstrated teleportation using on-demand photons from quantum dots. In their paper published in the journal Science Advances, the group explains how they accomplished this feat and how it applies to future quantum communications networks.

Scientists and many others are very interested in developing truly —it is believed that such networks will be safe from hacking or eavesdropping due to their very nature. But, as the researchers with this new effort point out, there are still some problems standing in the way. One of these is the difficulty in amplifying signals. One way to get around this problem, they note, is to generate photons on-demand as part of a quantum repeater—this helps to effectively handle the high clock rates. In this new effort, they have done just that, using semiconductor .

IonQ Quantum Computer Delivers More Processing Power Than Google’s

Posted by in categories: computing, quantum physics

IonQ, one of many companies developing a quantum computer, has announced a new trapped ion quantum computer with 79 processing qubits. The company claims this quantum computer should beat Google’s 72-qubit quantum computer, not just in terms of number of qubits, but also in total processing performance.
