By using quantum key distribution (QKD), quantum cryptographers can share information via theoretic secure keys between remote peers through physics-based protocols. The laws of quantum physics dictate that photons carrying signals cannot be amplified or […]
Rebooting a quantum computer is a tricky process that can damage its parts, but now two RIKEN physicists have proposed a fast and controllable way to hit reset. Click to rate this post! [Total: 0 […]
Materials that look like mosaics of triangular tiles at the atomic level sometimes have paradoxical properties, and quantum physicists have finally found out why. Click to rate this post! [Total: 0 Average: 0]You have already […]
A semiconducting material that performed a quantum “flip” from a conductor to an insulator above room temperature has been developed at the University of Michigan. It potentially brings the world closer to a new generation […]
An experiment, performed by Istituto Nazionale di Ricerca Metrologica (INRIM) on 200 km of the Italian Quantum Backbone, in collaboration with Toshiba Europe, shows that coherent laser interferometry considerably improves the performances of quantum key […]
Scientists from the Graduate School of Engineering Science at Osaka University used optical tweezers for the first time inside superfluid helium. With a strongly focused beam of light, they demonstrated the stable trapping of nanoparticles […]
Entanglement is a central phenomenon of quantum mechanics. It enables two photons to be connected with each other regardless of distance, and it is the basis of the immense potential of quantum technologies. However, the […]
The goal of nuclear physics is to describe all matter from its simplest building blocks: quarks and gluons. Found deep inside protons and neutrons, quarks and gluons also combine in less common configurations to make other […]
Numbers like π, e and φ often turn up in unexpected places in science and mathematics. Pascal’s triangle and the Fibonacci sequence also seem inexplicably widespread in nature. Then there’s the Riemann zeta function, a […]
Researchers at QuTech—a collaboration between the Delft University of Technology and TNO—have taken an important step for semiconductor spin qubits by surpassing the 99% barrier for two-qubit gate fidelity. They report on their findings in […]
