A Quantum Twist: Scientists Create “Hot” Schrödinger’s Cat States

Quantum physics has long required extreme precision and ultra-cold temperatures to observe its most mind-bending phenomena. But a breakthrough from researchers in Innsbruck, Austria, challenges that assumption—revealing that quantum states can persist even in warmer, less controlled environments. In a new study published in Science Advances, a team from the University of Innsbruck and the […]

Quantum Search for the Origin of Time Reveals No Distinction Between Past and Future

In search of the source of time, University of Surrey physicists Thomas Guff, Chintalpati Umashankar Shastry, and Andrea Rocco examined what they likened to a hot quantum bathtub beneath the endless stretch of eternity. No matter how hard we try, we can’t remember what will happen tomorrow—and physicists still don’t know why. They didn’t find

Quantum Mechanics was Established a Century Ago, and Physicists are Marking the Milestone

Physics, Quantum Physics / Marcílio Santos

A century ago, science embraced quantum principles. To commemorate this, physicists are hosting a year-long global celebration. In 1925, quantum mechanics began to take shape, offering a scientific theory that explains the counterintuitive behaviors of physics at microscopic scales. From that point onward, a series of groundbreaking papers established the theory’s foundation. Since then, quantum

Scientists Have Verified the Existence of a Third Type of Magnetism

Physics, Quantum Physics / Jorge Paka

Scientists 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 materials to

Physicists Discover a Groundbreaking Method to Entangle Light and Sound

Physics, Quantum Physics / Mauro Lucas

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 new concept: entangling

No, Chinese Quantum Computers Have not Broken Military-Grade Encryption

Quantum Physics / Leandro Conceição

Recent 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 quantum annealing to factor RSA-protected integers using Ising and QUBO models. The paper reports successful decryption of

Heaviest Clumps of Antimatter Ever Created in Particle Collider

Physics, Quantum Physics / Marcílio Santos

Physicists 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 Antimatter Antimatter consists of particles with the same mass as regular matter but with opposite charges. While this might sound mundane, the interaction between matter

Quantum Nonlocality: A Breakthrough in Quantum Entanglement

Physics, Quantum Physics, Science / Eduardo Paulo

In 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 the entanglement of three photons and their subsequent separation by hundreds of meters, proving a fundamental principle of quantum

New Study Suggests Gravity Exists Without Mass

Physics, Quantum Physics / Jorge Paka

What does gravity look like without mass? 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 matter A recent study proposes an unconventional idea: gravity could potentially exist without mass, offering an alternative to the concept of dark
