Ming-Cheng CHEN

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.
