Researchers demonstrate error-resistant quantum gates using exotic anyons for computation

The quantum computing revolution draws ever nearer, but the need for a computer that makes correctable errors continues to hold it back.

Through a collaboration with IBM led by Cornell, researchers have brought that revolution one step closer, achieving two major breakthroughs. First, they demonstrated an error-resistant implementation of universal quantum gates, the essential building blocks of quantum computation. Second, they showcased the power of a topological quantum computer in solving hard problems that a conventional computer couldn’t manage.

In the article “Realizing String-Net Condensation: Fibonacci Anyon Braiding for Universal Gates and Sampling Chromatic Polynomials” published in Nature Communications, an between researchers at IBM, Cornell, Harvard University and the Weizman Institute of Science demonstrated, for the first time, the ability to encode information by braiding—moving in a particular order—Fibonacci string net condensate (Fib SNC) anyons, which are exotic quasi-particles, in two dimensional space.

Patterns of patterns: Exploring supermoiré engineering

A few years ago, physicists were surprised to learn that stacking and subtly twisting two atomically thin layers of an electronic material like graphene creates a pattern that changes the material’s properties and can even turn it into a superconductor. This superimposed grid, like what would emerge if two window screens were laid slightly askew, is called a moiré pattern.

But why stop there? It turns out adding a third layer, with each layer twisted at slightly different angles, produces even more complex interferences known as supermoiré patterns (aka moiré of moiré). The supermoiré pattern induces profound changes in how electrons move through the material, but until recently, scientists had had trouble measuring exactly what changes occur and why.

Now, applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have used a specially designed microscope to probe the properties of supermoiré patterns in trilayer graphene to an extent that was never possible before. Using their microscope, they saw many new states of matter in which electrons would get stuck or form unusual groups, leading to changes in the entire system’s electronic behavior and opening doors to studying layered materials with precisely controllable properties.

Researchers certify genuine quantum behavior in computers with up to 73 qubits

Can you prove whether a large quantum system truly behaves according to the weird and wonderful rules of quantum mechanics—or if it just looks like it does? In a new study, physicists from Leiden, Beijing and Hangzhou found the answer to this question.

You could call it a “quantum lie detector”: Bell’s test designed by famous physicist John Bell. This test shows whether a machine, like a quantum computer, is truly using or just mimics them.

As quantum technologies become more mature, ever more stringent tests of quantumness become necessary. In this new study, the researchers took things to the next level, testing Bell correlations in systems with up to 73 qubits—the basic building blocks of a quantum computer.

Scientists unveil new way to control magnetism in super-thin materials

A powerful new method to control magnetic behavior in ultra-thin materials could lead to faster, smaller and more energy-efficient technologies, a study suggests.

Researchers have developed a new way to precisely tune magnetism using a material—called CrPS4—that is just a few atoms thick. The study is published in the journal Nature Materials.

The advance could solve a long-standing scientific problem and pave the way for the development of new smart magnetic technologies, from computer memory devices to next-generation electronics, the team says.

Researchers make key advances in radiation detection

Researchers in the Oregon State University College of Engineering have developed new technology for uranium enrichment measurement and trace element detection, vital for nuclear nonproliferation and supporting the development and operation of next-generation nuclear reactors.

“The technology that we are developing can support nuclear safeguards as well as nuclear energy development,” said Haori Yang, associate professor of nuclear science and engineering. “It can enable on-site enrichment measurements with minimal or no sample preparation, which means a quick turnaround time. It can also be used to monitor fuel in Gen-IV nuclear reactors, such as liquid metal–cooled reactors.”

In its naturally occurring state, uranium contains less than 1% U-235, the isotope that can sustain a nuclear chain reaction; the rest is U-238, which is much less able to do so.

Is Intelligence Genetic? Scientists Discover Heritable Brain State That Powers Cognitive Flexibility

Brain dynamics and cognition share genetic roots. Criticality may guide future brain health research. A recent study published on June 24 in PNAS presents strong evidence that brain criticality—the delicate balance between neural excitation and inhibition—is heavily influenced by genetic factors

What’s Missing in the Psychopathic Brain? Scientists Find Startling Clues

A research team has used the Julich-Brain Atlas to identify specific brain structures linked to antisocial behavior. A recent publication in the European Archives of Psychiatry and Clinical Neuroscience provides new insights into structural brain differences linked to psychopathy, a condition str

New PHP-Based Interlock RAT Variant Uses FileFix Delivery Mechanism to Target Multiple Industries

Threat actors behind the Interlock ransomware group have unleashed a new PHP variant of its bespoke remote access trojan (RAT) as part of a widespread campaign using a variant of ClickFix called FileFix.

“Since May 2025, activity related to the Interlock RAT has been observed in connection with the LandUpdate808 (aka KongTuke) web-inject threat clusters,” The DFIR Report said in a technical analysis published today in collaboration with Proofpoint.

“The campaign begins with compromised websites injected with a single-line script hidden in the page’s HTML, often unbeknownst to site owners or visitors.”
