New benchmark will reveal when quantum computers overtake the fastest supercomputers, scientists say
By Alan Bradley published
A new benchmark performed on chips from five different vendors has indicated how we can measure QPU performance as quantum computers become more advanced and useful.

'Squeezing' Schrödinger's cat-inspired qubits could lead to more reliable quantum computing
By Peter Ray Allison published
A new technique improves the reliability of cat qubits by squeezing their probabilistic states. This could improve their reliability and lifetime, and pave the way for accurate quantum computing.

Scientists observe new quantum phase that could have major implications for quantum computing
By Alan Bradley published
The exotic quantum phase, predicted over half a century ago, could lead to advances in quantum computing, sensors and communication technology.

What is quantum superposition?
By Jess Thomson last updated
Quantum superposition is a phenomenon in which a tiny particle can be in two states at the same time — but only if it is not being directly observed.

Quantum computing breakthrough could make 'noise' — forces that disrupt calculations — a thing of the past
By Ben Turner published
Useful quantum networks are hobbled by the problem of decoherence from environmental "noise." But a new breakthrough could change that.

MIT 'remote entanglement' discovery could lead to scalable 'quantum supercomputers'
By Alan Bradley published
A new device enables remote entanglement, allowing distant quantum processors to communicate with one another with reduced error rates.

Nvidia's mini desktop supercomputer gets launch window
By Alan Bradley published
The new DGX machines are portable but powerful enough to drive complex AI modules and research, with processing capabilities previously only available in data centers.

Quantum computers are a dream come true for hackers. Can we stop them?
By Joanna Thompson published
When quantum computers become commonplace, current cryptographic systems will become obsolete. Scientists are racing to get ahead of the problem and keep our data secure.

World's first light-powered neural processing units (NPUs) could massively reduce energy consumption in AI data centers
By Owen Hughes published
Q.ANT's new chip uses photon power in a bid to solve AI's big energy issue. It's also 50 times faster than silicon-based equivalents, the company says.

Scientists create ultra-efficient magnetic 'universal memory' that consumes much less energy than previous prototypes
By Peter Ray Allison published
MRAM can be energy-intensive, but a new generation of this technology will enable greater computing power and resilience, as well as much lower energy requirements.
