'This is easily the most powerful quantum computer on Earth': Scientists unveil Helios, a record-breaking quantum system
By Keumars Afifi-Sabet published
Scientists have built a 98-qubit machine that they say performs better than any other quantum computer in the world. They've used it to gain new insights into superconducting physics.

Google's breakthrough 'Quantum Echoes' algorithm pushes us closer to useful quantum computing — running 13,000 times faster than on a supercomputer
By Keumars Afifi-Sabet published
The new quantum computing algorithm, called "Quantum Echoes," is the first that can be independently verified by running it on another quantum computer.

Quantum computing 'lie detector' finally proves these machines tap into Einstein's spooky action at a distance rather than just faking it
By Tristan Greene published
Researchers developed an experimental method for confirming quantum activity in a quantum computing system.

'This moves the timeline forward significantly': Quantum computing breakthrough could slash pesky errors by up to 100 times
By Owen Hughes published
Researchers used a new technique called algorithmic fault tolerance (AFT) to cut the time and computational cost of quantum error correction by up to 100 times in simulations of neutral-atom architecture.

Quantum record smashed as scientists build mammoth 6,000-qubit system — and it works at room temperature
By Tristan Greene published
A new system, made by splitting a laser beam into 12,000 tweezers and trapping 6,100 neutral atom qubits, hit new heights for coherence times.

Scientists unveil world's first quantum computer built with regular silicon chips
By Alan Bradley published
A London-based startup has created the world's first full-stack quantum computer using a standard silicon CMOS chip fabrication process

Quantum internet inches closer thanks to new chip — it helps beam quantum signals over real-world fiber optic cables
By Owen Hughes published
Researchers used the Q‑Chip to send quantum data over standard fiber using Internet Protocol (IP), showing that future quantum networks could run on today’s internet infrastructure.

Tiny cryogenic device cuts quantum computer heat emissions by 10,000 times — and it could be launched in 2026
By Owen Hughes published
Scientists invent a new device that aims to solve thermal interference from electronic components — one of the biggest barriers to commercial quantum computing.

Japan launches its first homegrown quantum computer
By Keumars Afifi-Sabet published
Japan's first entirely homegrown quantum computer uses superconducting qubits and components made entirely domestically.

Meet the 'neglectons': Previously overlooked particles that could revolutionize quantum computing
By Larissa G. Capella published
When mathematicians revived ignored mathematical structures, they found that overlooked particles, called "neglectons," could complete the quantum computing puzzle.
