Underground Detector Reveals First Ghost Particle Findings

Leave a Comment / Physics, Quantum Physics, Uncategorized /

NEW YORK (AP) – Scientists operating a huge underground detector designed to study some of the universe’s most elusive particles announced their first major findings on Wednesday. The Jiangmen Underground Neutrino Observatory (JUNO) in China began gathering data in August to investigate neutrinos—tiny particles that have existed since the Big Bang. Invisible Particles Passing Through […]

Microsoft’s quantum chip got an upgrade. Critics are still skeptical

Leave a Comment / Physics, Quantum Physics /

Errors remain a major obstacle for quantum computers, disrupting calculations and limiting their ability to surpass conventional machines. Microsoft’s latest quantum chip is presented as a potential step forward—though only for those willing to accept the company’s claims. The company has introduced an upgraded quantum chip intended to be more resistant to errors. However, the

Physicists discovered something capable of traveling faster than light

Physics, Quantum Physics /

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

Physics, Quantum Physics /

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

Effects of Pointing Inaccuracies in Quantum key Distribution Systems

Physics, Quantum Physics /

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

Innovative Quantum Detection Technology is Reshaping Dark Matter Research

Physics, Quantum Physics /

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 /

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 /

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 /

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
