It might be counterintuitive, but that’s genuinely how quantum systems work.
The entangled photons are in a state of quantum superposition until they are measured, and that measurement creates information about the state of both photons.
It’s not a process that can be used to transmit information, it’s a process that transmits identical random numbers to two places at once that can’t be intercepted without breaking either their identicalness.
“Previous demonstrations of quantum teleportation have focused on transferring quantum states between physically separated systems,” said Dougal Main, from the Department of Physics at the University of Oxford, who led the study.
"In our study, we use quantum teleportation to create interactions between these distant systems. By carefully tailoring these interactions, we can perform logical quantum gates – the fundamental operations of quantum computing – between qubits housed in separate quantum computers.
“This breakthrough enables us to effectively ‘wire together’ distinct quantum processors into a single, fully-connected quantum computer.”
To simplify, they’re not just entangling pairs of photons and sending them out to two systems, but entangling entire qubits that exist on separate systems. This teleports the state of a qubit from one system to another without collapsing its superposition, enabling the quantum equivalent of parallel processing.
