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

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
