Breakthrough in quantum computing brings technology closer to large-scale practical use. Researchers at the University of Oxford have built a scalable quantum supercomputer capable of quantum teleportation, a major milestone in the field.
The breakthrough addresses the scalability problem that has hindered quantum computing’s practical use. The researchers claim their achievement will allow for industry-disrupting advancements. Quantum computers can store and transfer information using qubits, which enable faster processing than traditional bits.
This technology has the potential to be orders of magnitude more powerful than current supercomputers. However, it is not the first time quantum teleportation has been achieved; previous experiments transferred data between locations without physically moving qubits.
The Oxford researchers successfully teleported logical gates – the minimum components of an algorithm – across a network link. This breakthrough could form the foundation for a future “quantum internet” with ultra-secure communications, computation, and sensing capabilities.
According to Dougal Main, the study’s lead researcher, this achievement enables the connection of distinct quantum processors into a single, fully-connected quantum computer. The experiment demonstrates that network-distributed quantum information processing is feasible using current technology.
However, scaling up quantum computers remains a significant challenge that will require new physics insights and engineering effort in the coming years.
