MIT physicists propose a method to create fractionalized electrons known as non-Abelian anyons in two-dimensional materials, potentially advancing quantum computing by enabling more reliable quantum bits without using magnetic fields.
Their research highlights the potential of molybdenum ditelluride in forming these anyons, promising significant advancements in robust quantum computation.

Scientists have discovered that cosmic filaments, the largest known structures in the universe, are rotating. These massive, twisting filaments of dark matter and galaxies stretch across hundreds of millions of light-years and play a crucial role in channeling matter to galaxy clusters. The finding challenges existing theories, as it was previously believed that rotation could not occur on such large scales. The research was confirmed through both computer simulations and real-world data, and it opens up new questions about how these giant structures acquire their spin.
After reading the article, a Reddit user named Kane gained more than 100 upvotes with this comment: “What if galaxy clusters are like neuron and glial clusters in a brain. And dark matter is basically the equivalent of a synapse. It connects galaxies and matter together and is responsible for sending quantum information back and forth like a signal chain.”
In the world of science, even a small twist may carry immense implications for materials. Researchers at City University of Hong Kong have uncovered how a subtle rotation in 2D layers can give rise to a vortex electric field. This finding, published in Science, has the potential to impact electronic, magnetic, and optical devices as well as new applications in quantum computing, spintronics, and nanotechnology. According to Professor Ly Thuc Hue of CityUHK’s Department of Chemistry, the study demonstrates how “a simple twist in bilayer 2D materials” can induce this electric field, bypassing the need for costly thin-film deposition techniques.
Akin to solving intricate technical puzzles, researchers had to ensure clean, precisely aligned layers of material—a notoriously difficult challenge in the world of 2D materials. Twisted bilayers are made by stacking two thin layers of a material at a slight angle, creating unique electronic properties.
However, traditional methods of synthesizing these bilayers often limit the range of twist angles, particularly at smaller degrees, making exploration of their full potential nearly impossible. To address this, the team at City University of Hong Kong developed an ice-assisted transfer technique that uses a thin sheet of ice to align and transfer bilayers with precision.
A new study in Physical Review Letters demonstrates the levitation of a microparticle using nuclear magnetic resonance (NMR), having potential implications from biology to quantum computing.
NMR is a spectroscopic technique commonly used to analyze various materials based on how the atomic nuclei respond to external magnetic fields. This provides information about the internal structure, dynamics, and environment of the material.
One of the main challenges with NMR is using it on small objects to control the quantum properties of levitating microparticles.

Recently, Semafor received an extraordinary iMessage. It was from Rodney Gorham, a paralyzed ALS patient, and he had sent it directly from his brain. Gorham has a brain implant called Stentrode. Unlike previous generations of brain-computer interfaces, the Stentrode, from the neurotechnology company Synchron, can be implanted without invasive brain surgery. But… what *are* brain-computer interfaces? How do they work? And where is this novel technology going?

It is quite conventional that the working of classical computers is affected immensely by heat and one might have come across this situation in their lives when their computer failed to function properly due to excessive heating.
But what about quantum computers? Do thermodynamical factors influence the workings of a quantum computing device? Well, the answer is yes, quantum computers operate using quantum bits or qubits that essentially are in a superposed state exchanging information in binary code. An interesting fact about qubits is that they not only exchange information using 0 and 1 but also intermediate values between 0 and 1. These qubits are very sensitive, in that excessive heat generation could cause work-related defects which in a sense can cause harm to the device as a whole. Another crucial point is that in order to retrieve significant information from the qubit system, the associated quantum states must be dismantled and this could possibly impact the quantum system heavily in a negative manner as the process would be exothermic.
In recent work, physicists have investigated the thermodynamic effects caused by superconducting quantum systems [1]. The method involves the employment of a Josephson junction which essentially operates on the Josephson effect, an example of macroscopic quantum phenomena wherein a supercurrent flows between two superconductors placed end-to-end or in close proximity to each other. The principal usability of a Josephson junction is to store quantum information. Using superconductors is a plus because it helps enhance the efficiency of the qubits.
