Quantum computing has Huge potentialbut it faces a scalability issue. To make such machines practically useful, multiple quantum processors need to be assembled in one location. This increases the power of the processor, but also increases its size, making it more practical and refined. Scientists are working on something that sounds like in a science fiction series: connecting remote cores to each other through “quantum teleportation” to create more powerful machines.
The path to such information transmission begins to appear. 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 cores take advantage of their unique nature, bringing together their capabilities and forming a great computer to solve problems that neither of them can solve independently.
The team led by graduate student Dougal Main managed to obtain distant systems that can interact with each other and use quantum entanglement to share logic gates. Due to this quantum mechanical phenomenon, even at distances, a pair of linked particles can share the same state, and thus the same information can be transmitted. If one changes the state, the other immediately reflects the state.
Oxford scientists use quantum entanglement to send basic information between computers almost immediately. When data propagates long distances under this principle, it is said that “quantum transmission” occurs. This is not confused with the traditional concept of teleportation, which involves the hypothetical immediate exchange of matter in space. In the experiment, the light particles remain in the same position, but entanglement allows the computer to “view” each other’s information and work in parallel.
According to the team’s research papers natureusing photons and modules to separate two meters, quantum transmission using algorithms can be used. The fidelity of the information is 86%. The results of this distributed quantum computing architecture are enough to be a feasible path to large technologies. Quantum Internet.
Presentations of quantum transmission in computing environments have appeared before, but are limited to state transfers between systems. The Oxford University trial is unique because it uses remote injections to establish interactions between distant nuclei. “This breakthrough allows us to effectively connect different quantum processors to a fully connected quantum computer,” Main said.
If distributed quantum computing technology continues to evolve, the era of giant quantum machines may be behind us. Through quantum transmission, scalability issues can be solved by working together by more machines. Currently, the basic processor can process 50 QUAT, which is a quantum information. Some scientists estimate that machines capable of handling thousands or millions of qubits will need to solve complex problems.
Even without entanglement, quantum machines are already powerful enough to solve seemingly impossible problems. Willow, Google’s quantum chip, recently Resolved A benchmark task called random circuit sampling in five minutes; it can take up to 1 billion years for a traditional supercomputer to obtain the same results.
