Scientists achieve teleportation between quantum computers for the first time ever me 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.

Quantum teleportation and qubits
A qubit is valuable because it can be zero and one at the same moment, yet that superposition collapses if the qubit feels a nudge from the outside world.. 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.

Scientists have achieved a significant breakthrough by successfully teleporting information between two quantum computers. This involved transferring quantum state of a qubit (basic unit of quantum information) between separate quantum processors with 86% accuracy. The experiment, conducted by researchers at Oxford University, demonstrates  feasibility of distributed quantum computing could pave way for more powerful quantum computers.
