A team of researchers at the University of Ottawa and its Nexus for Quantum Technologies Institute, in collaboration with ...

Building useful quantum technologies—from sensors to computers—requires generating highly complex entangled states, in which the properties of particles are deeply intertwined. Producing such states ...

First formulated in 1935, the famous thought experiment attempts to explain the weirdness of quantum superposition, but a new study shows that this theoretical feline is really only the beginning of ...

Quantum computers still face limits when it comes to storing information. Researchers at ETH Zurich are now turning to ...

Quantum technologies are often associated with extraordinary complexity. The states that give quantum devices their potential advantage are notoriously difficult to create, maintain, and control. For ...

Quantum entanglement is often described as one of nature’s strangest secrets. Now, scientists have found it inside a crystal large enough to see without a microscope. The discovery shows that quantum ...

Quantum mechanical effects such as radioactive decay, or more generally: 'tunneling', display intriguing mathematical patterns. Researchers now show that a 40-year-old mathematical discovery can be ...

A centimeter-sized crystal has revealed clear signs of quantum entanglement, showing that large, everyday objects can display ...

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 ...
