Quantum networking has long sounded like science fiction, but a series of recent lab results is turning it into a practical engineering problem. Researchers are now pushing fragile quantum states ...

From sci‑fi vision to fiber‑optic engineering The core promise of a quantum internet is simple to state and hard to build: information encoded in quantum states would be impossible to copy without ...

Penn engineers have taken quantum networking from the lab to Verizon’s live fiber network, using a silicon “Q-chip” that speaks the same Internet Protocol as the modern web. The system pairs classical ...
