Technology EnglandQuantum Computing Takes Us One Step Closer to Teleportation!
Researchers affiliated with the University of Oxford, England, have built a scalable quantum supercomputer capable of quantum teleportation. This is a major milestone in quantum computing that will allow the next-generation technology to reach new heights.
“Previous demonstrations of quantum teleportation have focused on transferring quantum states between physically separated systems,” explains Dougal Main, from the Department of Physics at the University of Oxford, who led the study. “This breakthrough enables us to effectively ‘wire together’ distinct quantum processors into a single, fully connected quantum computer.”
The team focused on the so-called scalability problem of quantum computing. Even though quantum computing has been around for decades, the field has made significant advances in recent years towards realizing them on a practical scale. As in quantum physics, the next-generation machines replace traditional bits (ones and zeros to store and transfer digital information) with quantum bits (qubits) that can act like ones and zeros, but through a phenomenon called superposition. For the first time, scientists have managed to teleport logical gates (minimum components of an algorithm) across a network link. This quantum teleportation technique could potentially form the foundation for a future ‘quantum internet’ offering an ultra-secure network for communications, computation, and sensing.
