A new platform developed by Illinois Grainger engineers demonstrates the utility of a ytterbium-171 atom array in quantum networking. Their work represents a key step toward long-distance quantum ...

New device emits photons in telecom fiber band from the start, so it avoids a separate converter that can waste photons.

Quantum computers have the potential to solve complex problems that would be impossible for the most powerful classical supercomputer to crack. Just like a classical computer has separate yet ...

In 1964, physicist John Bell formulated what became known as Bell's Theorem, showing that if quantum mechanics is correct, such correlations cannot be explained by any hidden loca ...

Quantum networks, systems consisting of connected quantum computers, quantum sensors or other quantum devices, hold the ...
