Physicists at the University of Oxford have set a new global benchmark for the accuracy of controlling a single quantum bit, achieving the lowest-ever error rate for a quantum logic operation—just 0.000015%, or one error in 6.7 million operations. This record-breaking result represents nearly an order of magnitude improvement over the previous benchmark, set by the same research group a decade ago.

To put the result in perspective: a person is more likely to be struck by lightning in a given year (1 in 1.2 million) than for one of Oxford’s quantum logic gates to make a mistake.

The findings, to be published in Physical Review Letters, are a major advance towards having robust and useful quantum computers.

One of the current hot research topics is the combination of two of the most recent technological breakthroughs: machine learning and quantum computing.

An experimental study shows that already small-scale quantum computers can boost the performance of algorithms.

This was demonstrated on a photonic quantum processor by an international team of researchers at the University of Vienna. The work, published in Nature Photonics, shows promising for optical quantum computers.

Cambridge researchers created a quantum sensor using hBN, offering improved magnetic field detection over diamond-based sensors with new imaging possibilities. A team of physicists at the University of Cambridge has achieved a major breakthrough in quantum sensing by showing that spin defects in

IN A NUTSHELL 🌌 Quark-gluon plasma dominated the universe’s earliest microseconds, shaping the cosmos we know today. 🔬 Researchers used lattice QCD and Monte Carlo simulations to unravel the complexities of the strong nuclear force. 📈 The study revealed that even at extreme temperatures, the strong force influenced particle behavior more than previously believed. 📚
