Hexbyte Tech News Wired Why Google’s Quantum Victory Is a Huge Deal—and a Letdown

They finally did it. After years—no, decades—of declaring their hopes and dreams with hardly any practical results, researchers in the quantum computing community have delivered on a promise. Or have they?Last week, news leaked that researchers at Google and other institutions had solved a problem on a quantum computer 1 billion times faster than a…

Hexbyte News Computers Quantum Darwinism spotted in diamond spins – Physics World

Survival of the fittest: spins in diamond have been used to chart the transition between the quantum and classical worlds. (Courtesy: iStock) A handful of spins in diamond have shone new light on one of the most enduring mysteries in physics – how the objective reality of classical physics emerges from the murky, probabilistic quantum…

Hexbyte Hacker News Computers Deterministic quantum teleportation through fiber channels

AbstractQuantum teleportation, which is the transfer of an unknown quantum state from one station to another over a certain distance with the help of nonlocal entanglement shared by a sender and a receiver, has been widely used as a fundamental element in quantum communication and quantum computation. Optical fibers are crucial information channels, but teleportation…

Hexbyte Tech News Wired What Is Quantum Computing? The Complete WIRED Guide

Everything you ever wanted to know about qubits, superpositioning, and spooky action at a distance.Big things happen when computers get smaller. Or faster. And quantum computing is about chasing perhaps the biggest performance boost in the history of technology. The basic idea is to smash some barriers that limit the speed of existing computers by…

Silicon Valley is awash in hype about quantum computers. But these new machines—which perform calculations not only with bits (ones and zeros) but also with mysterious things called qubits—are still in their infancy. They are very large, very expensive, and must be kept very cold. Their applications are limited, and it will be likely a…

Hexbyte Tech News Wired Quantum Computing Will Create Jobs. But Which Ones?

Chris Monroe’s vision for quantum computers is simple: He wants people to use them. Monroe, a physicist and co-founder of the quantum computing startup IonQ, wants the machines to be as sleek as the iPhone. He wants people to code on them without needing to understand complicated quantum physics. Basically, he wants the devices to…
