| Outline of Final Research Achievements |
We investigated the computational power and the applications of large-scale quantum computers. We first rigorously established a quantum advantage (i.e., showed that quantum computers can be faster than supercomputers) for fundamental problems such as high-precision chemistry calculations. We developed several fast quantum distributed algorithms and proved a quantum advantage for distributed computing as well. We also investigated the potential of shallow (i.e., low depth) quantum circuits and demonstrated that they can be significantly more powerful than classical shallow circuits.
