Honeywell claims to have built the highest-performing quantum computer available

Multinational conglomerate Honeywell International Inc. is claiming to have built the highest-performing quantum computer available today. It made the announcement in a blogpost on its website. The company further claims that its H0 quantum computer has a quantum volume score of 64—making it twice as powerful as any other quantum computer available.

CERN Council endorses building larger supercollider

The CERN Council has unanimously endorsed the idea of building a newer, larger circular supercollider, dubbed the Future Circular Collider (FCC). The group made the announcement on June 19. The move is the first step toward building a 100 TeV 100-kilometer circumference collider around Geneva. As part of the vote, the group approved the launch of a technical and financial feasibility study for the new collider.

World's fastest Bose-Einstein condensate created

Researchers have created a Bose-Einstein condensate with record speed, creating the fascinating phase of matter in about 100 femtoseconds. To get an idea of how quick that is, hundred femtoseconds compared to one second is proportionally the same as a day compared to the age of the universe. The project was the result of a collaboration between Aalto University the and University of Eastern Finland.

A fresh twist in chiral topology

The concept of chirality is well-established in science: when an object cannot be superimposed on its mirror image, both the object and its mirror image are called chiral. In the drug industry, for instance, more than 50% of the pharmaceutically active molecules used nowadays are chiral molecules. While one of the 'enantiomers' is life-saving, its counterpart with opposite handedness may be poisonous. Another concept which has found widespread interest in contemporary materials science is topology, as many so-called topological materials feature exotic properties. For example, topological materials can have protected edge states where electrons flow freely without resistance, as if a superconducting path of electrons were created at the edge of a material. Such unconventional properties are a manifestation of the quantum nature of matter. The topological materials can be classified by a special quantum number, called the topological charge or the Chern number.

Strainoptronics: A new way to control photons

Researchers discovered a new way to engineer optoelectronic devices by stretching a two-dimensional material on top of a silicon photonic platform. Using this method, coined strainoptronics by a team led by George Washington University professor Volker Sorger, the researchers demonstrated for the first time that a 2-D material wrapped around a nanoscale silicon photonic waveguide creates a novel photodetector that can operate with high efficiency at the technology-critical wavelength of 1550 nanometers.

Experimentally identifying effective theories in many-body systems

One goal of science is to find physical descriptions of nature by studying how basic system components interact with one another. For complex many-body systems, effective theories are frequently used to this end. They allow describing the interactions without having to observe a system on the smallest of scales. Physicists at Heidelberg University have now developed a new method that makes it possible to identify such theories experimentally with the aid of so-called quantum simulators. The results of the research effort, led by Prof. Dr. Markus Oberthaler (experimental physics) and Prof. Dr. J├╝rgen Berges (theoretical physics), were published in the journal Nature Physics.

A Metal-like quantum gas: A pathbreaking platform for quantum simulation

Electronic properties of condensed matter are often determined by an intricate competition between kinetic energy that aims to overlap and delocalize electronic wave functions across the crystal lattice, and localizing electron-electron interactions. In contrast, the gaseous phase is characterized by valence electrons tightly localized around the ionic atom cores in discrete quantum states with well-defined energies. As an exotic hybrid of both situations, one may wonder which state of matter is created when a gas of isolated atoms is suddenly excited to a state where electronic wave functions spatially overlap, like in a solid?

New research deepens mystery of particle generation in proton collisions

A group of researchers including scientists from the RIKEN Nishina Center for Accelerator-Based Science, University of Tokyo, Nagoya University, and the Japan Atomic Energy Agency (JAEA) used the spin-polarized Relativistic Heavy Ion Collider at Brookhaven National Laboratory in the United States to show that, in polarized proton-proton collisions, neutral pions emitted in the very forward area of collisions—where direct interactions involving quarks and gluons are not applicable—still have a large degree of left-right asymmetry. This finding suggests that the previous consensus regarding the generation of particle in such collisions need to be reevaluated.

New design for 'optical ruler' could revolutionize clocks, telescopes, telecommunications

Just as a meter stick with hundreds of tick marks can be used to measure distances with great precision, a device known as a laser frequency comb, with its hundreds of evenly spaced, sharply defined frequencies, can be used to measure the colors of light waves with great precision.

A method to 3-D print components for refined neutron scattering

The Department of Energy's Oak Ridge National Laboratory has licensed a novel method to 3-D print components used in neutron instruments for scientific research to the ExOne Company, a leading maker of binder jet 3-D printing technology.

Microbubbles controlled by acoustical tweezers for highly localized drug release

Microbubbles are used every day as contrast agents in medical sonography, and are the subject of intense research for the delivery of therapeutic agents. There are a number of options available to manipulate these microbubbles, including the use of light and sound, although the potential of the latter remains largely unexplored.

Astronomy and Space news

Evidence supports 'hot start' scenario and early ocean formation on Pluto

The accretion of new material during Pluto's formation may have generated enough heat to create a liquid ocean that has persisted beneath an icy crust to the present day, despite the dwarf planet's orbit far from the sun in the cold outer reaches of the solar system.

Astronomers detect teraelectronvolt emission from the gamma-ray burst GRB 190114C

An international team of astronomers has detected a teraelectronvolt (TeV) emission from a gamma-ray burst designated GRB 190114C. The discovery could improve the understanding of very high energy (VHE) sources in the universe. The finding is detailed in a paper published June 12 on the arXiv pre-print repository.

Young giant planet offers clues to formation of exotic worlds

For most of human history our understanding of how planets form and evolve was based on the eight (or nine) planets in our solar system. But over the last 25 years, the discovery of more than 4,000 exoplanets, or planets outside our solar system, changed all that.

'Ring of fire' solar eclipse thrills skywatchers on longest day

Skywatchers along a narrow band from west Africa to the Arabian Peninsula, India and the Far East witnessed a dramatic "ring of fire" solar eclipse Sunday.

Scientists provide new explanation for the strange asymmetry of the moon

The Earth‐moon system's history remains mysterious. Scientists believe the system formed when a Mars‐sized body collided with the proto‐Earth. Earth ended up being the larger daughter of this collision and retained enough heat to become tectonically active. The moon, being smaller, likely cooled down faster and geologically froze. The apparent early dynamism of the moon challenges this idea.

NASA thinks it's time to return to Neptune with its Trident mission

Is it time to head back to Neptune and its moon Triton? It might be. After all, we have some unfinished business there.

Future space travelers may follow cosmic lighthouses

The Navy is testing beaming solar power in space

Solar power has become a focal point of the battle to mitigate climate change. The potential of solar power is massive—Earth receives as much solar energy in an hour as all of humanity uses in a year. Even with that much energy hitting the Earth, it is only a tiny fraction of the sun's overall output. Some of that other solar energy hits other planets, but most is just lost to the void of deep space.

From HAL 9000 to Westworld's Dolores: The pop culture robots that influenced smart voice assistants

Last year, nearly one third of Australian adults owned a smart speaker device allowing them to call on "Alexa" or "Siri." Now, with more time spent indoors due to COVID-19, smart voice assistants may be playing even bigger roles in people's lives.

AI could help solve the privacy problems it has created

The stunning successes of artificial intelligence would not have happened without the availability of massive amounts of data, whether its smart speakers in the home or personalized book recommendations. And the spread of AI into new areas of the economy, such as AI-driven marketing and self driving vehicles, has been driving the collection of ever more data. These large databases are amassing a wide variety of information, some of it sensitive and personally identifiable. All that data in one place makes such databases tempting targets, ratcheting up the risk of privacy breaches.

Self-driving taxis could be a setback for those with different needs – unless companies embrace accessible design now

Autonomous vehicles (AVs), like self-driving taxis, continue to garner media attention as industry and political stakeholders claim that they will improve safety and access to transportation for everyone. But for people who have different mobility needs and rely on human drivers for work beyond the task of driving, the prospect of driverless taxis may not sound like progress. Unless accommodations are built in to autonomous vehicle designs, companies risk undermining transportation access for the very communities this technology is promising to include.
