A new technical proposal by Chinese scientists for conventional computers breaks the speed record of Sycamore, Google’s quantum computer!!
Sycamore is the most powerful quantum computer currently owned by Google. Due to the peculiarity of qubits, its basic units of information, it is capable of solving a task in 200 seconds that would take a conventional supercomputer 10,000 years to complete. Because of this, Google claims that Sycamore has “quantum supremacy,” a formal concept of computing that describes quantum computing systems that are capable of performing processes that are impossible not only for certain conventional computers, but for any traditional computing system.
A new effort by Chinese scientists has just called into question Google’s quantum supremacy. In just 14.22 seconds, an innovative parallel computing system solved a problem that took Sycamore 600 seconds to complete. They used bits as a basis like a conventional computer, had 2,304 graphical processing units (GPU), and saved energy in the process. The research, which has not yet been peer-reviewed, is available through a preprint on the Arxiv server.
The Sycamore problem was solved in only 14.22 seconds with an energy consumption of 2.39 kWh. In contrast, Google needed 4.3 kWh of energy to solve the same operation in 600 seconds.
