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

Quantum computers have the potential of outperforming classical computers in some optimization and data processing tasks. However, quantum systems are also more sensitive to noise and thus prone to ...

Jainendra K. Jain's theory of composite fermions belongs firmly in the second category.Get breaking news anytime, anywhere.

Scientists used swirling water waves to simulate a quantum effect, uncovering rotating nodal patterns that could deepen understanding of hidden quantum phenomena.

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 ...

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 ...

Quantum entanglement is often described as one of nature’s strangest secrets. Now, scientists have found it inside a crystal ...

Some of the most promising tasks in which quantum computers can offer practical speedups over their classical counterparts can be found in the fields of quantum chemistry and simulation (see e.g. 3 ...

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, ...

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 ...
