Cool for cats

Boffins working for Microsoft and Atom Computing have emerged from their smoke-filled shared lab claiming a significant breakthrough in their quest to develop fault-tolerant quantum computers that outperform classical systems.

25,000 times faster than predecessor

Quantum computing outfit D-Wage has been whipping its quantum cats into shape and lifted the kimono a new 4,400-plus-qubit quantum processing unit (QPU) named Advantage2.

Better at herding the cats

IBM has announced a series of developments to make limited but functional quantum calculations possible ahead of the much-anticipated arrival of error-corrected quantum computing.

Encryption is potentially dead and alive

Chinese boffins have used a D-Wave quantum computer to mount a successful quantum attack on widely used encryption algorithms.

Riverlane’s founder says

Quantum computing will experience its "Sputnik" breakthrough within the coming years, according to Steve Brierley, the founder of Cambridge-based Riverlane.

The cat in the PC case is both dead and alive

Microsoft and Quantinuum have won significantly in the battle against quantum error correction. Using Quantinuum's ion-trap hardware and Microsoft's fresh-off-the-press qubit visualisation system, the team ran a whopping 14,000 experiments without the cat upsetting anything.

Neither dead nor alive yet

While quantum computing companies have said their machines could be doing amazing things in just a few years, some top experts say they don't believe the hype.

More cats make fewer errors

A team of boffins has built a quantum computer with the largest number of logical qubits (quantum bits).

20-qubits

VTT Technical Research Centre of Finland and IQM Quantum Computers have completed Finland’s second quantum computer.

Give it the muscle it needs

Quantum computing could turbo-charge AI into something "massively, universally transformative," according to the South China Morning Post.
