Google uses a quantum computer and calculates 10,000 years in 200 seconds
The technology giant said it achieved “quantum supremacy,” allegedly through an experimental demonstration of the superiority of a quantum computer over a traditional computer, according to an article published in NASA, which was later removed from the site.
Google would have done an experiment with randomly generated numbers and produced through a scenario specialized in quantum phenomena. The researchers said they determined that their quantum computer outperformed ordinary computers in the task, which involved calculating the output of certain specialized circuits.
“While our processor takes about 200 seconds to test an example of the quantum circuit a million times, a next-generation supercomputer would need about 10,000 years to perform the equivalent task,” the researchers said.
Google’s quantum computer, nicknamed “Sycamore,” contained 53 qubits, or “quantum bits,” a measure of machine power. The equipment came from a 72-qubits device, nicknamed “Bristlecone”, which had been previously designed.
Researchers estimate that performing the same experiment on a Google Cloud server would take 50 billion hours, too much time to be feasible. In the quantum processor, it only took 30 seconds, according to the findings of the researchers.
