That's a yotta. No, seriously. The prefix for 1024 is "yotta". The reason I remember that bit of trivia goes back to 2007's "Global Warming, Al Gore and Eleanor Clift".
From IEEE Spectrum:
Chinese optical quantum computer Jiuzhang 2.0 can solve a problem 10^24 faster than a classical computer
Quantum computers Zuchongzi and Jiuzhang 2.0 may both display "quantum primacy" over classical computers
Two of the most powerful quantum computers in the world to date now both come from China, and new experiments with them re-ignite the controversy over what kinds of problems might be quantum computationally solvable that couldn't begin to be solved by a conventional supercomputer.
A quantum computer with great enough complexity—for instance, enough components known as quantum bits or “qubits"—could in theory achieve a "quantum advantage" allowing it to find the answers to problems no classical computer could ever solve. In principle, a quantum computer with 300 qubits could perform more calculations in an instant than there are atoms in the visible universe.
In 2019, Google argued it displayed such "quantum primacy" with its 53-qubit Sycamore processor, carrying out a calculation in 200 seconds that the company estimated would take Summit, the world's most powerful supercomputer at that time, 10,000 years. However, IBM researchers later called that quantum advantage claim in question, arguing that with better classical algorithms, Summit could actually solve that problem in 2.5 days.
“The current state of the art is that no experiments have demonstrated quantum advantage for practical tasks yet."
—Chao-Yang Lu, The University of Science and Technology of ChinaNow scientists in China have tested two different quantum computers on what they say are more challenging tasks than Sycamore faced and showed faster results. They note their work points to "an unambiguous quantum computational advantage."
In one study, the researchers experimented with Zuchongzi, which used 56 superconducting qubits on a task whose solutions are random instances, or samples, from a given spread of probabilities. They found Zuchongzi completed such a sampling task in 1.2 hours, one they estimated would take Summit at least 8.2 years to finish. They also noted this sampling task was tens to hundreds of times more computationally demanding than what Google used to establish quantum advantage with Sycamore....
