Is there a quantum computer in the world?

The number 1 is Japanese Fugaku: the peak performance is 5372 12.00Tflops(Tflops is trillions of floating-point operations per second) and the continuous performance is 4420 10.00Tflops.

The second place is the peak of America: peak performance of 200794.90Tflops, continuous performance of 148600.00Tflops.

The third place is Sierra (Ridge) of the United States: peak performance 1257 12.00Tflops, continuous performance of 94640.00Tflops.

The fourth place is China's "Shenwei Light of Taihu Lake": peak performance 125435.90Tflops, continuous performance 930 14.60Tflops.

The main participants in quantum computing can be divided into four categories:

The first category is international technology giants, such as IBM, Google, Honeywell and so on.

The second category is quantum computing startups, such as Rigetti and IonQ.

The third category is national scientific research institutes, such as Fermilab, Argonne National Laboratory and Institute of Quantum Information and Quantum Science and Technology Innovation of Chinese Academy of Sciences.

The fourth category is high-level research universities, such as Cambridge University, China University of Science and Technology, Harvard University and so on.
