It's necessary to explore multiple computational strata—including those yet to be discovered—that will underpin the creation ...

Oxford scientists teleported quantum gates across six feet, linking separate processors. This step could lead to modular quantum computing.

The implementation is based on an advanced multi-qubit gate with single-qubit gate fidelities above 99.9% and two-qubit gate fidelities above 99%.

But while classical gates manipulate binary bits (0s and 1s), quantum gates operate on qubits—which can achieve what are called superpositions, existing in multiple states simultaneously.
