GarryKillian//Getty ImagesScientists have recently developed and captured images of a new magnetic substance called altermagnetic material. Unlike some discoveries that take decades to materialize after being theorized, altermagnetism has quickly gained attention in the scientific community. In a new paper published in the peer-reviewed journal Nature, researchers demonstrate their ability to precisely tune these...
(Alasabyss/Creatas Video+/Getty Images Plus)Quantum entanglement, a cornerstone of modern physics, involves correlating two or more unmeasured particles so that their properties intertwine and mirror each other. When one particle is measured, its counterpart’s corresponding properties instantly solidify, even when the two are separated by vast distances.In a groundbreaking development, physicists have introduced a bold...
Hacking a 50-bit RSA key is so easy you could do it with your cell phone in secondsRecent headlines claim Chinese researchers used D-Wave quantum computers to hack RSA, AES, and "military-grade encryption." This is both true and misleading.A May 2024 white paper in the Chinese Journal of Computers details how researchers used D-Wave's...
An illustration of the newly discovered antimatter nucleus, antihyperhydrogen-4Institute of Modern Physics, ChinaPhysicists have achieved a significant milestone by producing the heaviest antimatter clumps ever recorded. These clumps, known as antihyperhydrogen-4, could provide insights into some of physics' most complex questions.Understanding AntimatterAntimatter consists of particles with the same mass as regular matter but...
Prof. Tongcang Li (left), Dr. Yuanbin Jin (middle) and Kunhong Shen perform experiments with levitated and rotating fluorescent diamonds at Purdue UniversityPhysicists at Purdue University levitated nanoscale diamonds, making them glow and spin at 1.2 billion rpm with lasers. These experiments could greatly advance quantum physics research.Creating Quantum-Ready Nanodiamonds via High PressureThe nanodiamonds,...
The achievement of three-way entanglement is a significant advancement towards the realization of a global quantum internet.Kristina Armitage/Quanta MagazineIn August 2023, researchers in Hefei, China, achieved a groundbreaking milestone in the realm of quantum physics by demonstrating three-way quantum nonlocality. This experiment, conducted at the University of Science and Technology of China (USTC), involved...

Newton's groundbreaking laws universally define gravity's effects, while Einstein's concept of warped spacetime describes it in terms of curvature. Traditionally, scientists have associated gravity solely with matterA recent study proposes an unconventional idea: gravity could potentially exist without mass, offering an alternative to the concept of...
