"Scientists achieve teleportation between quantum computers for the first time ever"
By Eric Ralls

-By teleporting a qubit’s identity rather than physically hauling the particle around, engineers sidestep much of that fragility. The receiving end simply reshapes its own qubit to mirror the original and carries on with the calculation.
The latest experiment used a pair of “network” qubits – atoms optimized for sending and receiving optical signals – and a pair of “circuit” qubits dedicated to crunching data.
Teleportation bridged the network qubits first; the entangled link then let the circuit qubits act as though they shared the same chip.
That separation may sound modest, yet even a six-foot gap lets designers slide in upgrades, repairs, or entirely new hardware without cracking open a refrigerated chamber the size of a wardrobe.
The approach also keeps communication overhead low. Quantum gate teleportation needs just one entangled pair and two classical bits to pull off a two-qubit gate across the network.
-Engineers can keep asking for entangled pairs until they get a clean one, wasting no precious quantum information in the meantime. That efficiency could shave years off the timeline for a functional quantum data center.
