Physicists discovered something capable of traveling faster than light

For the first time, physicists have directly observed that “holes” within light can travel faster than the light surrounding them. These features, called phase singularities or optical vortices, were predicted decades ago. Since the 1970s, scientists have suggested that, much like whirlpools in a river can move faster than the water itself, swirling gaps within […]

Quantum Teleportation was Achieved over the Internet for the First Time

In 2024, researchers in the US successfully teleported a quantum state of light over more than 30 kilometers (about 18 miles) of fiber optic cable, even amid heavy internet traffic—a feat once thought impossible. While it won’t help you skip your commute or speed up streaming, transmitting quantum states through existing infrastructure marks a major

The XFELO Laser Creates Highly Focused, Ultra-Precise X-Ray Beams

Physics / Valeriano Ndeyi

A group of engineers and scientists has demonstrated for the first time that a hard X-ray cavity can achieve net X-ray gain. In their experiment, crystal mirrors repeatedly reflected the X-ray pulses, amplifying them in a process similar to that of an optical laser. This proof-of-concept at the European XFEL produced an exceptionally coherent, laser-like

The World’s Longest-Running Lab Experiment Nears 100 Years

Computational Physics, Physics / Eduardo Paulo

Science can sometimes move at a glacial pace. Data trickles in slowly, truth emerges gradually, and certainty is often hard-won. The world’s longest-running lab experiment embodies this kind of extreme patience. It has been ongoing for nearly a century, overseen by successive custodians and observed by countless onlookers, as the experiment proceeds at an almost

Effects of Pointing Inaccuracies in Quantum key Distribution Systems

Physics, Quantum Physics / Ngoma Manuel

Quantum key distribution (QKD) is a developing communication technology that applies the principles of quantum mechanics to achieve extremely secure information exchange between two parties. It enables a sender and a receiver to actively establish a shared secret key, even when an adversary may be monitoring the communication channel. Any eavesdropping attempt disturbs the quantum

The Strongest Hypergravity Machine Reaches 1,900× Earth’s Gravity

Nuclear & Particles, Physics / Ngoma Manuel

China has surpassed both its own and U.S. records by constructing a massive underground hypergravity centrifuge capable of simulating forces up to 1,900 times Earth’s gravity, delivering unprecedented experimental power. Developed by Shanghai Electric Nuclear Power Group for China’s CHIEF facility, the new CHIEF1900 centrifuge will soon reach 1,900 g‑tonnes, surpassing the CHIEF1300. Simulating Extreme

Innovative Quantum Detection Technology is Reshaping Dark Matter Research

Physics, Quantum Physics / Jorge Paka

In our quest to comprehend the universe, our knowledge represents just a tiny fraction of the full reality. Dark matter and dark energy constitute roughly 95% of the universe, leaving a mere 5% as “ordinary matter” that we can directly observe. Dr. Rupak Mahapatra, an experimental particle physicist at Texas A&M University, develops cutting-edge semiconductor

A Unique Form of Quantumness may be Key to Quantum Computers Success

Physics, Quantum Physics / Jorge Paka

Google researchers used their Willow quantum computer to show that quantum contextuality may be essential to its computational power. What gives quantum computers their edge over classical machines? A new experiment suggests that “quantum contextuality” could be a crucial factor. How Qubits Redefine Computing Quantum computers differ fundamentally from conventional machines because they exploit uniquely

Searching for Dark Matter Axions Using a Quantum-Enhanced Haloscope

Physics, Quantum Physics / Valeriano Ndeyi

Axions are theoretical lightweight particles that may address two major puzzles in physics: they could explain why certain nuclear interactions preserve time symmetry and may also make up dark matter. Dark matter itself does not emit, reflect, or absorb light and has yet to be directly detected. Axions are extremely light, hypothetical particles believed to

Scientists Confirm Successful Quantum Teleportation Between Photons

Physics, Quantum Physics / Marcílio Santos

Stuttgart team teleports quantum state between separate photonsThis breakthrough enables quantum information to travel long distances through repeaters made of ‘quantum dots’ without loss or interference. Unlike standard internet signals, which can be amplified along the way, quantum information requires photons that are nearly identical. Quantum dots—special semiconductors that emit light at extremely precise frequencies—can
