Correlated errors in quantum computers emphasize need for design changes

Quantum computers could outperform classical computers at many tasks, but only if the errors that are an inevitable part of computational tasks are isolated rather than widespread events. Now, researchers at the University of Wisconsin-Madison have found evidence that errors are correlated across an entire superconducting quantum computing chip—highlighting a problem that must be acknowledged and addressed in the quest for fault-tolerant quantum computers.

New super-resolution microscopy method approaches the atomic scale

Scientists at Weill Cornell Medicine have developed a computational technique that greatly increases the resolution of atomic force microscopy, a specialized type of microscope that "feels" the atoms at a surface. The method reveals atomic-level details on proteins and other biological structures under normal physiological conditions, opening a new window on cell biology, virology and other microscopic processes.

Researchers uncover unique properties of a promising new superconductor

An international team of physicists led by the University of Minnesota has discovered that a unique superconducting metal is more resilient when used as a very thin layer. The research is the first step toward a larger goal of understanding unconventional superconducting states in materials, which could possibly be used in quantum computing in the future.

Nematic transition and nanoscale suppression of superconductivity in an iron chalcogenide

In unconventional superconductors, electrons often exhibit a tendency towards spatial ordering within their atomic structure.

When testing Einstein's theory of general relativity, small modeling errors add up fast

Small modeling errors may accumulate faster than previously expected when physicists combine multiple gravitational wave events (such as colliding black holes) to test Albert Einstein's theory of general relativity, suggest researchers at the University of Birmingham in the United Kingdom. The findings, published June 16 in the journal iScience, suggest that catalogs with as few as 10 to 30 events with a signal-to-background noise ratio of 20 (which is typical for events used in this type of test) could provide misleading deviations from general relativity, erroneously pointing to new physics where none exists. Because this is close to the size of current catalogs used to assess Einstein's theory, the authors conclude that physicists should proceed with caution when performing such experiments.

Seeing the invisible: Tiny crystal films could make night vision an everyday reality

It's a familiar vision to anyone who has watched a lot of action movies or played Call of Duty: a ghostly green image that makes invisible objects visible. Since the development of the first night-vision devices in the mid-1960s, the technology has captured the popular imagination.

Quantum-nonlocality at all speeds

The phenomenon of quantum nonlocality defies our everyday intuition. It shows the strong correlations between several quantum particles some of which change their state instantaneously when the others are measured, regardless of the distance between them. While this phenomenon has been confirmed for slow moving particles, it has been debated whether nonlocality is preserved when particles move very fast at velocities close to the speed of light, and even more so when those velocities are quantum mechanically indefinite. Now, researchers from the University of Vienna, the Austrian Academy of Sciences and the Perimeter Institute report in the latest issue of Physical Review Letters that nonlocality is a universal property of the world, regardless of how and at what speed quantum particles move.

Particles with 'eyes' allow a closer look at rotational dynamics

Colloids—mixtures of particles made from one substance, dispersed in another substance—crop up in numerous areas of everyday life, including cosmetics, food and dyes, and form important systems within our bodies. Understanding the behavior of colloids therefore has wide-ranging implications, yet investigating the rotation of spherical particles has been challenging. Now, an international team including researchers from The University of Tokyo Institute of Industrial Science has created particles with an off-center core or "eye" that can be tracked using microscopy. Their findings are published in Physical Review X.

Using microorganisms to quickly monitor water quality

Researchers from the Singapore University of Technology and Design (SUTD) have demonstrated a technology that rapidly detects pollutants in water by measuring their impacts on swimming microorganisms.

Scientists identify properties that allow proteins to strengthen under pressure

A new rubber band stretches, but then snaps back into its original shape and size. Stretched again, it does the same. But what if the rubber band was made of a material that remembered how it had been stretched? Just as our bones strengthen in response to impact, medical implants or prosthetics composed of such a material could adjust to environmental pressures such as those encountered in strenuous exercise.

The amazing world of flame balls, doughnuts and horseshoes

Flame balls are gentle and fragile spherical flames that up till recently could only exist in conditions of near-zero gravity. Researchers at TU/e have managed to observe flameballs at normal earth-bound conditions, and thus, discovered new insights in the working of lean fuel mixtures. Lean hydrogen mixtures are believed to be the fuel of the future as they emit no CO2 and only low concentrations of nitrogen oxides. Join our researchers in their exciting journey to understand the enigmatic flame ball.

Astronomy and Space news

Mystery of Betelgeuse's dip in brightness solved

When Betelgeuse, a bright orange star in the constellation of Orion, became visibly darker in late 2019 and early 2020, the astronomy community was puzzled. A team of astronomers have now published new images of the star's surface, taken using the European Southern Observatory's Very Large Telescope (ESO's VLT), that clearly show how its brightness changed. The new research reveals that the star was partially concealed by a cloud of dust, a discovery that solves the mystery of the Great Dimming of Betelgeuse.

Study investigates the behavior of magnetar SGR J1745–2900

Using NASA's Nuclear Spectroscopic Telescope Array (NuSTAR), Russian astronomers have investigated the behavior of a magnetar known as SGR J1745–2900 after its outburst in April 2013. Results of the study, published June 9 on, could be essential to better understand the nature of this magnetar.

Study points to a seed black hole produced by a dark matter halo collapse

Supermassive black holes, or SMBHs, are black holes with masses that are several million to billion times the mass of our sun. The Milky Way hosts an SMBH with mass a few million times the solar mass. Surprisingly, astrophysical observations show that SMBHs already existed when the universe was very young. For example, a billion solar mass black holes are found when the universe was just 6% of its current age, 13.7 billion years. How do these SMBHs in the early universe originate?

Space scientists solve a decades-long gamma-ray burst puzzle

An international team of scientists, led by astrophysicists from the University of Bath in the UK, has measured the magnetic field in a far-off Gamma-Ray Burst, confirming for the first time a decades-long theoretical prediction—that the magnetic field in these blast waves becomes scrambled after the ejected material crashes into, and shocks, the surrounding medium.

Total solar eclipses shine a light on the solar wind with help from NASA's ACE mission

From traversing sand dunes in the Sahara Desert to keeping watch for polar bears in the Arctic, a group of solar scientists known as the "Solar Wind Sherpas" led by Shadia Habbal, have traveled to the ends of the Earth to scientifically observe total solar eclipses—the fleeting moments when the Moon completely blocks the Sun, temporarily turning day into night. With the images, they've uncovered a surprising finding about the Sun's wind and its wispy outer atmosphere—the corona—which is only visible in its entirety during an eclipse.

Rare triple galaxy merger with at least two supermassive black holes

One of the best things about that universe is that there is so much to it. If you look hard enough, you can most likely find any combination of astronomical events happening. Not long ago, we reported on research that found seven separate instances of three galaxies colliding with one another. Now, a team led by Jonathan Williams of the University of Maryland has found another triple galaxy merging cluster, but this one might potentially have two active supermassive black holes, allowing astronomers to peer into the system dynamics of two of the universe's most extreme objects running into one another.

A backdoor in mobile phone encryption from the '90s still exists

The encryption algorithm GEA-1 was implemented in mobile phones in the 1990s to encrypt data connections. Since then, it has been kept secret. Now, a research team from Ruhr-Universität Bochum (RUB), together with colleagues from France and Norway, has analyzed the algorithm and has come to the following conclusion: GEA-1 is so easy to break that it must be a deliberately weak encryption that was built in as a backdoor. Although the vulnerability is still present in many modern mobile phones, it no longer poses any significant threat to users, according to the researchers.

Electrohydraulic arachno-bot offers light weight robotic articulation

A team of researchers at the Max Planck Institute for Intelligent Systems in Germany and at the University of Boulder in Colorado in the US has found a new way to exploit the principles of spiders' joints to drive articulated robots without any bulky components and connectors, which weigh down the robot and reduce portability and speed. Their slender and lightweight simple structures impress by enabling a robot to jump 10 times its height. At the end of May, the team's work titled "Spider-inspired electrohydraulic actuators for fast, soft-actuated joints" was published in Advanced Science.
