Researchers from the University of Oxford have demonstrated quantum teleportation by connecting two quantum processors separated by six and a half feet using a photonic network interface. Led by graduate student Dougal Main, the team aims to lay the foundation for a quantum internet composed of ultra-secure processors. While previous studies have achieved state transfer of qubits, this breakthrough allows for performing fundamental quantum computing operations across distant systems, potentially overcoming challenges faced in scaling up quantum computers.
"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, essentially the equivalent of linking traditional computers to create a supercomputer."
