A new study by researchers at the Massachusetts Institute of Technology (MIT) has bridged the gap between quantum and classical physics. This study shows that mathematical ideas from classical physics can be used to explain the strange and “spooky” behavior attributed to quantum particles. Despite the development of applications such as quantum computing and sensing, … Read more
In the world of quantum physics, incredible events unfold with astonishing speed. Processes that were thought to occur instantaneously, such as quantum entanglement, are now directly measured in fractions of a second, or attoseconds. It’s like freezing a moment in time to reveal the subtle details hidden in the mundane. Professor Joachim Burgdorfer … Read more
It was a dizzying discovery. In 2018, Japanese researchers claimed to have found concrete evidence of an elusive particle, Majorana fermions, in a quantum spin liquid called ruthenium trichloride. Majoranas are very popular among quantum materials scientists because, when the pairs are localized or trapped, they can safely encode information and form stable qubits, the … Read more
When you throw a ball into the air, the equations of classical physics tell you exactly what path it will take as it falls, and exactly when and where it will land. However, if you squeeze the same ball down to a subatomic size, it will behave in ways that cannot be predicted by classical … Read more
The arrow of time moves forward. Eggs don’t break. Milk won’t spill. But now, new research has discovered a way to reverse this arrow in quantum systems, causing events to flip-flop as if time were flowing backwards. The finding is theoretical at this point, but could be tested experimentally, said Luis Pedro García-Pintos, a physicist … Read more

Quantum computers, once thought to be decades away, are now much closer than expected thanks to the work of researchers at the California Institute of Technology and ETH Zurich. Quantum computers are causing a huge stir in the scientific and technical community because they have the potential to outperform … Read more
For many years, physicists have treated knowledge as a kind of fuel in the quantum world, allowing us to know systems more precisely. You can squeeze more work out of it. But this well-valued assumption is now under attack. Researchers have shown in a new study that even a quantum state’s complete uncertainty does not … Read more
Muon-catalyzed fusion is one of those strange concepts that holds enough promise to intrigue researchers, but stubbornly resists practical application. The central idea underlying this process is to replace the electrons in the hydrogen with heavier particles called muons, which draw the atomic nuclei so close together that nuclear fusion (a process that occurs at … Read more
Scientists in the US have discovered that hematite features a rare new form of magnetism, which reportedly paves the way for spintronics technology that could transform data processing and storage. The discovery, made by researchers at Oak Ridge National Laboratory (ORNL), provided one of the clearest experimental evidence of alternating magnetism, a newly confirmed third … Read more
