The promise of quantum computing come with a hitch: the more qubits you load into a single machine, the harder they are to keep in line. Scientists have tried shielding, error correction, even stacking qubits on top of one another, yet stability keeps slipping through their fingers.
A fresh demonstration now points to a different strategy – spreading the workload across several small processors and letting quantum teleportation knit them together in real time.
A quantum state of light was successfully teleported through more than 30 kilometers (around 18 miles) of fiber optic cable amid a torrent of internet traffic – a feat of engineering once considered impossible.
The impressive demonstration by researchers in the US in 2024 may not help you beam to work to beat the morning traffic, or download your favourite cat videos faster.
However, the ability to teleport quantum states through existing infrastructure represents a monumental step towards achieving a quantum-connected computing network, enhanced encryption, or powerful new methods of sensing.

"This is incredibly exciting because nobody thought it was possible," says Prem Kumar, a Northwestern University computing engineer who led the study. READ MORE...
