Quantum: Loophole-​Free Bell Test with Superconducting Circuits (ETH Zurich)

A new technical paper titled "Loophole-free Bell inequality violation with superconducting circuits" was published by a group of researchers led by ETH Zurich. Abstract (partial) "Here we demonstrate a loophole-free violation of Bell’s inequality with superconducting circuits, which are a prime contender for realizing quantum computing technology. To evaluate a Clauser–Horne–Shimony... » read more

Quantum Computers And CMOS Semiconductors: A Review And Future Predictions

With the advent of quantum computing, the need for peripheral fault-tolerant logic control circuitry has reached new heights. In classical computation, the unit of information is a “1” or “0”. In quantum computers, the unit of information is a qubit which can be characterized as a “0”, “1”, or a superposition of both values (known as a “superimposed state”). The control c... » read more

System Bits: June 25

Supercomputers around the world At last week’s International Supercomputing Conference in Frankfurt, Germany, the 53rd biannual list of the Top500 of the most powerful computing systems in the world was released. Broken out by countries of installation, China has 219 of the world’s 500 fastest supercomputers, compared with 116 in the United States. Ranking by percent of list flops, the ... » read more

System Bits: Sept.1

The quantum description of nature In quantum mechanics, the underlying physical rules that govern the fundamental behavior of matter and light at the atomic scale state that nothing can quite be completely at rest, but now for the first time, a team of researchers from Caltech, McGill University, and the Max Planck Institute for the Science of Light has found a way to observe—and control—t... » read more
