From cybersecurity to banking, supply chain to medicines, and military to weather forecasting, quantum computing has the potential to have a profound influence on a wide range of industries. Making ...

Several years ago one of us, Toni, asked another of us, Marco, to come to his office at the Institute of Photonic Sciences, a large research center in Castelldefels near Barcelona. “There is a problem ...

A century ago, the strange behavior of atoms and elementary particles led physicists to formulate a new theory of nature. That theory, quantum mechanics, found immediate success, proving its worth ...

It may be a decade or more before quantum computers become common enough that we’ll find out whether “post-quantum cryptography” will stand up to genuine quantum computers. In the meantime, some ...

Isn't it ionic: An artist's representation of Quantinuum's 56-qubit trapped-ion quantum computer. Researchers used this computer to demonstrate a way of generating random numbers, then using a ...
