“This is one of those tautologies for which the answer is yes and no. As “virtual” particles they can mediate interactions, but never appear as observable particles in their own right, which allows them more flexibility, such as virtual photons not being massless or having ...
In this paper, we propose a simple method to simultaneously generate the entanglement between macroscopic objects (mechanical oscillators) and entanglement between microscopic objects (photons) based on a coupled cavity-optomechanical system. We show that when the cavity-optomechanical system works in the...
Q: Why does energy have to be positive (and real)? Q: How does the Twin Paradox work? Q: How can photons have energy and momentum, but no mass? Q: If you were on the inside of the Sun...
Entanglement of photons is a fundamental feature of quantum mechanics, which stands at the core of quantum technologies such as photonic quantum computing, communication, and sensing. An ongoing challenge in all these is finding an efficient and controll
Raman spectroscopy measures the energy shifts of scattered electrons relative to the energy of photons from a monochromatic light source, reflecting the chemical bonds within a sample. This generates a spectral fingerprint since the Raman shift correlates directly with the interacting molecules (which are...
It is the interference that slows the phase velocity through through the material; the individual photons continue to "move" at the speed of light,$c$, but the effective motion of the phase front is slowed. Richard Feynman devotes some time to this in his lectures onQED: The Strange Theory...
Unity ML-Agents Toolkit is an open-source platform created by Unity Technologies that allows users to create machine learning (ML) models within the Unity game development environment. It enables game designers to include intelligent, learning-based behaviors into game characters and things. ...
In addition to CiViQ, the QT Flagship supports other consortia to achieve high data security. The Quantum Flagship news item notes that "researchers at QRANGE have created quantumrandom number generatorsthat can be implemented in such protocols; and UNIQORN scientists are searching for ways to mini...
millions of new studies would come out. That has already been a problem for a while, thus IBM created a supercomputer and its algorithm,IBM Watson, to sift through millions of studies in a second – although there is some uncertainty about what will happen to these initiatives after thesale...
So, hopefully, each of the entangled photons will be in that same state and will interfere similarly, with similar results. Unfortunately, that’s not the case even a little. The entangled photons are created in the state ; a combination of “both up” and “both ...
