Best of both worlds — Combining classical and quantum systems to meet supercomputing demands: Scientists detect strongly entangled pair of protons on a nanocrystalline silicon surface, potentially enabling new levels of high-speed computing

One of the most interesting phenomena in quantum mechanics is "quantum entanglement." This phenomenon describes how certain particles are inextricably linked, such that their states can only be described with reference to each other. This particle interaction also forms the basis of quantum computing. And this is why, in recent years, physicists have looked for techniques to generate entanglement. However, these techniques confront a number of engineering hurdles, including limitations in creating large number of "qubits" (quantum bits, the basic unit of quantum information), the need to maintain extremely low temperatures (
