Quantum computing has enormous potentialBut it faces a scalability problem. In order for such a machine to be real, several quantum processors must be compiled in one place. This increases the performance of a processor, but also its size and makes it less practical and more sensitive. Scientists work on a solution that sounds like something from a science fiction series: combine the connection of long -distance nuclei by “quantumentel reporting” in order to create even more powerful machines.
The path for such information transmission is displayed. A team of scientists at the University of Oxford recently sent the first quantum algorithm wirelessly between two separate quantum processors. The two small nuclei used their unique nature, polished their skills and formed a superior computer to solve problems that none of them could solve independently.
The team under the direction of Dougal Main, student Dougal Main, managed to interact with each other removed systems and to share logic gates using quantum knitting. Thanks to this quantum mechanical phenomenon, a few linked particles can also share the same state in the distance and therefore transmit the same information. If one changes, the other reflects it immediately.
The Oxford scientists used quantum knitting to send basic information between computers almost immediately. If data take long distances according to this principle, “quantum removal” should have occurred. This should not be confused with the conventional idea of teleportation, which includes a hypothetical immediate exchange of matter in space. In the experiment, the light particles remained in the same place, but the falsification enabled the computers to “see” the information of the other and function in parallel.
After the research work of the team in published in NatureThe quantum recovery of an algorithm was possible with photons and modules that were separated by two meters. The reproduction of the information had an 86 percent rate. The result of this distributed quantum computer architecture is good enough to a practical way to the large-scale technology and the as an internet.
Previously, demonstrations of the quantumentel portation were created in arithmetic contexts, but were limited to the transfer of conditions between systems. The attempt at the University of Oxford can be distinguished because it used teleportation to create interactions between remote cores. “This breakthrough enables us to effectively connect different quantum processors into a single, fully connected quantum computer,” said Haupt.
If the distributed quantum computer technology is developing, the era of the huge quantum machines can be behind us. The problem of scalability could possibly be solved with more machines that work through quantum removal. For the time being, a basic processor can process 50 qubits, a unit with quantum information. Some scientists estimate that a machine with the ability to process thousands or millions of qubits is needed to solve complex problems.
Even without entanglement, quantum machines are already powerful enough to solve seemingly impossible problems. Willow, Google Quantum Chip, recently solved a benchmark task, which is called Random Circuit sampling in five minutes; It would have taken up to 10 quadrillion years for a conventional supercomputer to achieve the same result.
