Physicists demonstrate magnetometer that uses quantum effects and machine learning
Researchers from the Moscow Institute of Physics and Technology (MIPT), Aalto University in Finland, and ETH Zurich have demonstrated a prototype device that uses quantum effects and machine learning to measure magnetic fields more accurately than its classical analogues. Such measurements are needed to seek mineral deposits, discover distant astronomical objects, diagnose brain disorders, and create better radars.
“When you study nature, whether you investigate the human brain or a supernova explosion, you always deal with some sort of electromagnetic signals,” explains Andrey Lebedev, a co-author of the paper describing the new device in npj Quantum Information. “So measuring magnetic fields is necessary across diverse areas of science and technology, and one would want to do this as accurately as possible.”
Scientists Worldwide Are Getting Serious About Quantum Internet
It takes little more than logging on to see the flaws in today’s internet—mainly, how easy it is to steal or intercept data. One future solution for these problems could be an upgrade that relies on the latest advances in the science of subatomic particles: a quantum internet.
Just last week, three scientists from the renowned QuTech center at the Delft University of Technology (TU Delft) revealed a roadmap for how this quantum internet should develop. They also plan to connect four cities with a quantum link by 2020, reports MIT Tech Review. And today, University of Chicago scientists announced that they plan to set up a quantum link across a 30-mile distance. Scientists are really getting serious about this quantum internet idea.
Artificial intelligence controls quantum computers
Quantum computers could solve complex tasks that are beyond the capabilities of conventional computers. However, the quantum states are extremely sensitive to constant interference from their environment. The plan is to combat this using active protection based on quantum error correction. Florian Marquardt, Director at the Max Planck Institute for the Science of Light, and his team have now presented a quantum error correction system that is capable of learning thanks to artificial intelligence.

Here’s what the quantum internet has in store
A future ‘quantum internet’ could find use long before it reaches technological maturity, a team of physicists predicts.
Such a network, which exploits the unique effects of quantum physics, would be fundamentally different to the classical Internet we use today, and research groups worldwide are already working on its early stages of development. The first stages promise virtually unbreakable privacy and security in communications; a more mature network could include a range of applications for science and beyond that aren’t possible with classical systems, including quantum sensors that can detect gravitational waves.
