Electrons typically travel at high speeds, zipping through matter unbound. In the 1930s, physicist Eugene Wigner predicted that electrons could be coaxed into stillness at low densities and cold temperatures, forming an electron ice that would later be called the Wigner crystal.
New observations of microscopic vortices confirm the existence of a paradoxical phase of matter that may also arise inside neutron stars.
A black hole formula worked out in the 1970s remains the most concrete clue physicists have about the threads of the space-time fabric.
In a study published in Physical Review Letters, researchers at the Center for Computational Quantum Physics (CCQ) at the Flatiron Institute have revealed that the quantum problem they solved, which involved a specific two-dimensional quantum system of flipping magnets, exhibits a behavior known as confinement. This problem explains why they defeated the quantum computer in its own game. Only one-dimensional systems had previously exhibited this behavior in quantum condensed matter physics.
The researchers revealed earlier this year that they had completely surpassed a quantum computer at a task that some believed could only be completed by quantum computers by using a classical computer and complex mathematical models.
According to lead author Joseph Tindall, a research fellow at the CCQ, this surprising discovery is giving researchers a framework for evaluating novel quantum simulations and aiding in their understanding of the boundary between quantum and classical computers’ capabilities.
There’s just one catch: every atom in your body would be fully disassembled to the quantum level, effectively leaving your original body totally destroyed.
Researchers at Chalmers University of Technology in Sweden and at the University of Magdeburg in Germany have developed a novel type of nanomechanical resonator that combines two important features: high mechanical quality and piezoelectricity. This development could open doors to new possibilities in quantum sensing technologies.

Researchers at the Large Hadron Collider (LHC), the world’s largest particle accelerator, have recently made a groundbreaking advancement in exploring the laws of nature. They have observed the phenomenon of quantum entanglement between top quarks, the heaviest elementary particles, at unprecedented energy levels. This breakthrough paves the way for new possibilities in particle physics and could unveil new aspects of the fundamental forces that govern the universe.
Quantum Entanglement: A Counterintuitive Phenomenon
Quantum entanglement is one of the most enigmatic phenomena in quantum mechanics. It occurs when two or more particles become interconnected in such a way that the state of one particle instantly influences another, regardless of the distance separating them. This defies our everyday intuition and challenges some classical physics concepts, like causality.
On this episode, neuroscientist and author Robert Sapolsky joins Nate to discuss the structure of the human brain and its implication on behavior and our ability to change. Dr. Sapolsky also unpacks how the innate quality of a biological organism shaped by evolution and the surrounding environment — meaning all animals, including humans — leads him to believe that there is no such thing as free will, at least how we think about it today. How do our past and present hormone levels, hunger, stress, and more affect the way we make decisions? What implications does this have in a future headed towards lower energy and resource availability? How can our species manage the mismatch of our evolutionary biology with our modern day challenges — and navigate through a ‘determined’ future?
