Quantum computing Great potential, but with a scalability problem. In order for such a device to be useful, several quantum processors must be assembled in a single location. This increases the power of a processor but also its size and makes it less practical and delicate. Scientists are working on a solution that seems to be something of a series of sci -fi stories: connecting remote cores through “quantum transportation” to create even more powerful machines.
The data transfer path is starting to work. Recently, a team of scientists at the University of Oxford was able to send the first quantum algorithm wirelessly between two separate quantum processors. These two small kernels used their unique nature, gathered their abilities, and formed a superior computer to solve problems that none of them could solve independently.
The team, led by Dougal Mine’s graduate student, succeeded in gaining remote systems to interact with each other and sharing logic gates using quantum conflict. Thanks to this quantum mechanical phenomenon, a pair of relevant particles, even remotely, can share in the same state and thus convey the same information. If one changes, the other will immediately reflect it.
Oxford scientists used quantum involvement to almost immediately send basic information between computers. When data travels long distances, it is said that “quantum transportation” has occurred. This should not be confused with the conventional remote idea, which includes the immediate impedimental exchange of matter in space. In the experiment, the light particles remain in the same place, but the computers allowed computers to “see” each other’s information and work in parallel.
According to the team’s research article published in nature, quantum transportation was possible with a two -meter algorithm with photons and modules separated by two meters. Information loyalty was 86 %. The result of this architecture of distributed quantum computing is good enough to be a good way for large -scale technology and quantum Internet.
Quantum transportation manifestations have already occurred in computational areas, but have been limited to the transfer of modes between systems. Oxford University trial is distinct because it uses Teleportation to interact with distant nuclei. “This achievement allows us to effectively connect different quantum processors to a fully connected quantum computer,” the original said.
If distributed quantum computing technology is still developing, it may be the era of giant quantum machines behind us. The problem of scalability can potentially be resolved by more devices that work through quantum transportation. Currently, a fundamental processor can handle 50 Qubits, a quantum information unit. Some scientists estimate that a device with a capacity of thousands of or millions of dollars will be needed to solve complex problems.
Even without conflict, quantum machines are now strong enough to solve seemingly impossible problems. Willow, Google’s quantum chip, has recently solved a criterion called random circuit sampling in five minutes. It takes up to 10 years to reach a regular supercomputer to achieve a similar result.
