MIT engineers develop a hybrid process that connects photonics with “artificial atoms,” to produce the largest quantum chip of its type.
MIT researchers have developed a process to manufacture and integrate “artificial atoms,” created by atomic-scale defects in microscopically thin slices of diamond, with photonic circuitry, producing the largest quantum chip of its type.
The accomplishment “marks a turning point” in the field of scalable quantum processors, says Dirk Englund, an associate professor in MIT’s Department of Electrical Engineering and Computer Science. Millions of quantum processors will be needed to build quantum computers, and the new research demonstrates a viable way to scale up processor production, he and his colleagues note.
Berkeley Lab researchers are part of an international team that reports a high-sensitivity measurement by underground CUPID-Mo experiment.
Nuclear physicists affiliated with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) played a leading role in analyzing data for a demonstration experiment that has achieved record precision for a specialized detector material.
The CUPID-Mo experiment is among a field of experiments that are using a variety of approaches to detect a theorized particle process, called neutrinoless double-beta decay, that could revise our understanding of ghostly particles called neutrinos, and of their role in the formation of the universe.
Chemists at the University of Wisconsin-Madison and their collaborators have created a highly efficient and long-lasting solar flow battery, a way to generate, store and redeliver renewable electricity from the sun in one device.
The new device is made of silicon solar cells combined with advanced solar materials integrated with optimally designed chemical components. The solar flow battery, made by the Song Jin lab in the UW-Madison chemistry department, achieved a new record efficiency of 20 percent. That bests most commercially available silicon solar cells used today and is 40 percent more efficient than the previous record holder for solar flow batteries, also developed by the Jin lab.
Evidence has emerged for long-proposed, but previously unconfirmed quasiparticles called anyons. The concept of anyons goes back 43 years, and physicists have found evidence collections of particles are behaving as anyons for some time, but have lacked confirmation. Now, within months of each other, two teams have found different methods to verify that this is what they are dealing with that look much more conclusive.
The universe’s particles are divided into two sorts; fermions and bosons. Fermions, including the components of atoms, cannot occupy the same quantum state as each other while bosons, which include photons of light, have no such problem.
Anyone who has spent much time around physicists will not be surprised to learn that many have wondered if there could be something else. For some, the so-called “particle zoo” is never sufficiently weird and wonderful. This led to the proposal of anyons, which can only exist in two-dimensional space.
A proposed new mission to Venus
Posted in space travel
The proposed VERITAS mission to Venus is one of the finalists for NASA’s Discovery Program. If selected, it will revolutionize our knowledge about the planet’s geology and how this formerly habitable world became a fiery wasteland.
Cardiff University scientists have devised a new way of making reactions up to 70 times faster by using state-of-the-art equipment to spin chemicals around.
They found that efficient mixing within a chemical reaction could be achieved by spinning chemicals and catalysts around in a small tube, causing the reactions to happen much quicker.
The new findings could have a profound influence on the way that chemicals are made in a wide variety of industries, from drug development to agriculture and fragrances.
Circa 2019
The European Space Agency (ESA) study is investigating how practical constructing a manned base on the moon only using 3D printing technology could be, given that it would rely primarily on lunar dirt for building materials.
“Terrestrial 3D printing technology has produced entire structures,” Laurent Pambaguian, who heads the project for ESA, said in a statement. “Our industrial team investigated if it could similarly be employed to build a lunar habitat.”
Circa 2016
“In 2050 there will be trillions of self-replicating robot factories on the asteroid belt,” he tells the audience at WIRED2016.
“A few million years later, AI will colonise the galaxy. Humans are not going to play a big role there, but that’s ok. We should be proud of being part of a grand process that transcends humankind more than the industrial revolution. It is comparable to the invention of life itself, and I am privileged to live this moment and witness the beginnings of this.” — Jürgen Schmidhuber
Nuclear fission
Posted in military, nuclear energy, particle physics
Is a process in nuclear physics in which the nucleus of an atom splits into two or more smaller nuclei as fission products, and usually some by-product particles. Hence, fission is a form of elemental transmutation. The by-products include free neutrons, photons usually in the form gamma rays, and other nuclear fragments such as beta particles and alpha particles. Fission of heavy elements is an exothermic reaction and can release substantial amounts of useful energy both as gamma rays and as kinetic energy of the fragments (heating the bulk material where fission takes place). Nuclear fission produces energy for nuclear power and to drive explosion of nuclear weapons.
