Oxford Scientists say they’ve achieved quantum teleportation, between two computers.
Quantum gates enable quantum computers to perform multiple calculations through superposition—the ability of qubits to be both zero and one simultaneously.
One major challenge in quantum computing has been scalability. A computer processing millions of qubits would need to be massive, making it impractical for most users.
Qubits, or quantum bits, replace traditional bits in computing. Instead of building a giant machine, this discovery allows data to be transferred between smaller, interconnected devices.
Unlike regular bits, which store information as either zero or one, qubits can exist in both states at the same time, vastly increasing computing power.

The scientists linked two quantum processors two meters apart using a “photonic network interface,” detailed in the journal Nature.
Quantum teleportation breakthrough could pave the way for a “quantum internet,” where separate processors connect to form an ultra-secure communication and data network, safe from hacking.
This advancement brings large-scale quantum computing closer to reality and moves us toward a future where data can be transmitted instantly and securely over a quantum internet.
