Preserving quantum information is key to developing useful quantum computing systems. But interacting quantum systems are chaotic and follow laws of thermodynamics, eventually leading to information ...

Scientists built a quantum gate linking four-state photons, showing complex quantum tasks can be done with fewer steps using qudits.

A team in China has demonstrated the simultaneous teleportation of multiple sideband qumodes in a continuous-variable system, overcoming a longstanding technical barrier.

Duplicating the information held in quantum computers was thought to be impossible thanks to the no-cloning theorem, but researchers have now found a workaround ...

New evidence suggests a rare triplet superconductor may help quantum computers stay in sync by preserving electron spin ...

Quantum computers—devices that process information using quantum mechanical effects—have long been expected to outperform classical systems on certain tasks. Over the past few decades, researchers ...

A pair of photons enters an optical maze, and sometimes they leave as something new. Not new in the everyday sense, since both were still photons when they came out.

Scientists have pulled off a feat long considered out of reach: getting light to mimic the famous quantum Hall effect. In ...

Researchers from the University of Arizona, University of Maryland, and NASA’s Goddard Space Flight Center have proposed a ...
