We released a paper (preprint) for calculating transition amplitudes of molecules, which are important quantities in photochemistry, authored by Ibe, Nakagawa, Yamamoto, and Mitarai from QunaSys Inc. and Dr. Gao and Dr. Kobayashi at Mitsubishi Chemical Corp. Science & Innovation Center.

QunaSys Inc. is excited to announce the close of a $2.5 million Series A investment from three experienced VCs based in Japan; Global Brain Corporation, Shinsei Corporate Investment and ANRI. The funds will be used to speed-up our R&D towards practical application of quantum computer.

We released a new algorithm called orbital optimized unitary coupled cluster (OO-UCC) for improving the efficiency of chemistry calculations on a quantum computer with our advisor Assoc. Prof. Wataru Mizukami (Quantum information and biology division, Osaka Univ.) as the first author of the paper (preprint). Mitarai, Nakagawa, Yamamoto, and Yan at QunaSys Inc. and Dr. Ohnishi at JSR Corporation contributed to the work as co-authors.

Endo (intern), Kurata (intern), and Nakagawa from QunaSys Inc. proposed a near-term quantum algorithm for computing the Green’s function, which is crucial for analyzing properties of molecules and materials.  Now you can read the preprint of the paper on arXiv.

QunaSys today announce start of Joint-Research with Mitsubishi Chemical for research on precise control of optical properties of organic materials, utilizing quantum computer.

Yoshioka, Nakagawa, and Mitarai from QunaSys Inc., and our advisor, Prof. Fujii, published a paper (preprint) that proposed an algorithm named “dissipative-system Variational Quantum Eigensolver (dVQE)” to simulate the non-equilibrium steady state on a quantum computer.

We started collaborating with Microsoft Quantum.

We launched quantum algorithm competition website, Quantaggle.

QunaSys today announce start of Joint-Research with JXTG Holdings for research on Quantum Computer applications.

 Mitarai, Nakagawa of QunaSys Inc., and our advisor, Dr. Mizukami, published a paper (preprint) that proposed an algorithm to calculate molecular energy derivatives analytically on a quantum computer.
