Challenging Extended Church-Turing Thesis through the demonstration of quantum computational advantage.

University of Science and Technology of China

Ming-cheng Chen works on quantum physics, particularly on the fundamental issues of quantum mechanics and the application of quantum computing using single photons, single atoms, and superconducting artificial atoms.

In quantum mechanics fundamentals, he has experimentally achieved direct measurements of the real and imaginary parts of quantum wave function through quantum teleportation, established the physical objectivity of complex numbers through Bell tests on quantum entanglement swapping, and observed quantum violations of the pigeonhole principle through three-photon interference, challenging the natural counting law. In quantum computing, he and his team demonstrated the optical quantum computational advantage for the first time through the implementation of the "Jiuzhang" photonic quantum computer, which is 100 trillion times faster than the then world's top-ranked supercomputer "Fugaku" in Gaussian Boson sampling tasks. He also contributed to the demonstration of the superconducting quantum computational advantage, beyond Google's "Sycamore" quantum supremacy, through the "Zuchongzhi" superconducting quantum computer.
