To predict when we’ll have a truly useful quantum computer, we need to know precisely what one is. Columnist Karmela Padavic-Callaghan finds that’s harder to pin down than you might think ...

Microchips for quantum processors shown in a clean room laboratory at the Physikalisch-Technische Bundesanstalt in Braunschweig, Germany. Quantum computers, like fusion reactors and personalized ...

Netherlands-based QuiX Quantum has delivered Carina, the world's first universal photonic quantum computer designed for customer deployment. Unlike most quantum machines, Carina operates at room ...

Applied computing is a multidisciplinary field that blends the theoretical and practical aspects of computing to solve day-to-day business and industry problems—integrating computing with other ...

Quantum computing's biggest challenge isn't speed - it's proving results are correct. Here's why verification matters more ...

Computing is part of everything we do. Computing drives innovation in engineering, business, entertainment, education, and the sciences—and it provides solutions to complex, challenging problems of ...

As the name suggests, neuromorphic computing uses a model that's inspired by the workings of the brain. The brain makes a really appealing model for computing: unlike most supercomputers, which fill ...

A close-up view of an IBM quantum computer. The processor is in the silver-colored cylinder. The wiring transmits control signals in and computing results out. For years, quantum computing has been ...

Quantum computing, once the realm of science fiction, could bring massive economic gains. But it also threatens to upend national security, and governments are racing to prepare. Quantum computers ...

The pure plays are so risky that it makes sense to consider investing in their suppliers instead.

To hear some tell it, quantum computing progress will soon stall, ushering in a “quantum winter” when big companies ice their development programs and investors stop lavishing investments on startups.

This article is part of a package on the future of quantum computing. Read about the most promising applications of these machines here and see an illustrated field guide to qubits here. Inside a ...
