Building useful quantum technologies—from sensors to computers—requires generating highly complex entangled states, in which ...

A team at the University of Chicago has discovered a surprisingly simple way to create powerful quantum states that are normally difficult to produce. By making small adjustments to the energy levels ...

Entanglement sits at the heart of quantum technology, but it is rarely easy to make. The most powerful states often demand ...

It's one thing to dream up a quantum internet that could send hacker-proof information around the world via photons superimposed in different quantum states. It's quite another to physically show it's ...

New research suggests that fleeting quantum forces leave lasting imprints on the brain, subtly influencing thought, intuition ...

Researchers from the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, and Johns Hopkins University in ...

Schrödinger’s cat, famously, is both alive and dead – but what if it could be something else as well? Researchers at the ...

Quantum entanglement can link two objects even when they are separated by extremely large distances. But a new study has found a limit at which such quantum correlations stop – and surprisingly, ...

Quantum information systems, systems that process, store or transmit information leveraging quantum mechanical effects, could, in principle, outperform classical systems in some optimization, ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...
