In the quantum realm, not even time flows as you might expect

A team of physicists at the Universities of Bristol, Vienna, the Balearic Islands and the Institute for Quantum Optics and Quantum Information (IQOQI-Vienna) has shown how quantum systems can simultaneously evolve along two ...

Study: Machine learning a useful tool for quantum control

In the everyday world, we can perform measurements with nearly unlimited precision. But in the quantum world—the realm of atoms, electrons, photons, and other tiny particles—this becomes much harder. Every measurement ...

Exotic magnetic states in miniature dimensions

We are all used to the idea that simpler units in nature interact to form complex structures. Take, for example, the hierarchy of life, where atoms combine to form molecules, molecules combine to form cells, cells combine ...

Exploring quantum systems that don't find equilibrium

Some physical systems, especially in the quantum world, do not reach a stable equilibrium even after a long time. An ETH researcher has now found an elegant explanation for this phenomenon.

Researchers demonstrate a quantum advantage

Quantum computing and quantum sensing have the potential to be vastly more powerful than their classical counterparts. Not only could a fully realized quantum computer take just seconds to solve equations that would take ...
