History of quantum computing: 12 key moments that shaped the future of computers
Although quantum computing is a nascent field, there are plenty of key moments that defined it over the last few decades as scientists strive to create machines that can solve impossible problems.
What is a quantum processing unit (QPU)?
At the core of a quantum computer is the quantum processor, but these technologies are vastly different from the CPUs found in conventional computers.
What is a quantum bit (qubit)?
Qubits are the fundamental building blocks of quantum computers — and, when fitted into these machines — rely on the weird laws of quantum mechanics to process calculations in parallel.
Japan to start building 1st 'zeta-class' supercomputer in 2025, 1,000 times more powerful than today's fastest machines
Japan's new state-of-the-art supercomputer, which is due to cost more than $750 million to build, is set to turn on by 2030.
Radical quantum computing theory could lead to more powerful machines than previously imagined
Scientists have just theorized how to connect quantum processors over vast distances to form a giant quantum computing network that acts as a single machine.
Prototype quantum processor boasts record 99.9% qubit fidelity
IQM's quantum processor achieved 99.9% fidelity in recent tests, the company says. Here's what that actually means.
China's upgraded light-powered 'AGI chip' is now a million times more efficient than before, researchers say
The Taichi-II chiplet, which could one day power super-intelligent AI models, ups the ante in light-based processing.
Quantum compasses closer to replacing GPS after scientists squeeze key refrigerator-sized laser system onto a microchip
Quantum compasses need six atom interferometers, each the size of a small room, to work. But scientists have made crucial steps to miniaturizing these devices.
