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.
Teleportation in this context doesn’t fling matter through space. Instead, it transfers a qubit’s delicate “both-at-once” state to a partner qubit some distance away, using entanglement and a quick burst of old-fashioned binary data.
Until recently, practical attempts rarely pushed beyond proof-of-concept.
Now researchers have used the teleportation trick to forge a working logic gate between two separate quantum chips sitting about six feet apart, hinting at a future where clusters of modest processors act as one mighty computer.
