Quantum computing has enormous potential, but it faces a scalability problem. For such a machine to be useful in real terms, multiple quantum processors need to be assembled in a single location. This increases a processor’s power but also its size, making it less practical and more delicate. Scientists are working on a solution that sounds like something out of a science fiction series: connecting remote cores to each other through “quantum teleportation” to create even more powerful machines.
The path to such information transmission is beginning to appear. Recently, a team of scientists at the University of Oxford was able to send the first quantum algorithm wirelessly between two
