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

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.

The collaboration of TU Wien with research groups in China has resulted in a crucial building block for a new kind of quantum computer: The realization of a novel type of quantum logic gate makes it ...

Quantum computing and on-chip quantum information processing are rapidly advancing fields with the potential to revolutionize traditional computation and communication. However, integrating quantum ...
