Business
ByteDance Inc, enters quantum computing
A paper “Toward Practical Quantum Embedding Simulation of Realistic Chemical Systems on Near-term Quantum Computers,” published in an updated preprint at arXiv.org on Sept. 17, 2021 shows that ByteDance Inc, as the first participating institution, has designed a hybrid quantum and classical algorithm that can efficiently simulate and compute the properties of small molecules.The research implies the possibility of solving industrial chemistry problems on near-term quantum devices, and is a strong boost to quantum computing industry-academia research. This is the first time to obtain the research progress related to quantum computing in the field of ByteDance Inc, and also marks the official entry of ByteDance Inc into the field of quantum computing.

Peking University makes important progress in quantum state tomography of molecules by ultrafast diffraction
Peking University has establish a new variant of quantum state tomography for ultrafast electron diffraction to characterize the molecular quantum states. The ability to reconstruct the density matrix, which encodes the amplitude and phase of the wavepacket, for molecules of arbitrary degrees of freedom, will enable the reconstruction of a quantum molecular movie from experimental x-ray or electron diffraction data. The related research results have been published in Nature Communications on September 14.

Nanjing University makes important progress in quantum phase transition
Professor Lei Wang from Nanjing University and Columbia University have jointly use transport measurements to characterize metal–insulator transitions (MITs) in twisted WSe2 near half filling of the first moiré subband. These results establish twisted WSe2 as a new platform to study doping and bandwidth-controlled metal–insulator quantum phase transitions on the triangular lattice. The research results have been published in Nature on September 15.
