Exponential quantum speedups in quantum chemistry with linear depth

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Oskar Leimkuhler, K. Birgitta Whaley, , , | Summary: We prove classical simulation hardness, under the generalized $mathsf{P}neqmathsf{NP}$ conjecture, for quantum circuit families with applications in near-term quantum chemical ground state estimation. The proof exploits a connection to particle number conserving matchgate circuits with fermionic magic state […]

Predicting performance-related properties of refrigerant based on tailored small-molecule functional group contribution

Kavli Affiliate: Xiang Zhang | First 5 Authors: Peilin Cao, Ying Geng, Nan Feng, Xiang Zhang, Zhiwen Qi | Summary: As current group contribution (GC) methods are mostly proposed for a wide size-range of molecules, applying them to property prediction of small refrigerant molecules could lead to unacceptable errors. In this sense, for the design […]

Imaging Odd-Parity Quasiparticle Interference in the Superconductive Surface State of UTe2

Kavli Affiliate: J. C. Seamus Davis | First 5 Authors: Shuqiu Wang, Kuanysh Zhussupbekov, Joseph P. Carroll, Bin Hu, Xiaolong Liu | Summary: Although no known material definitely exhibits intrinsic topological superconductivity, where a spin-triplet electron pairing potential $Delta(k)$ has odd parity, UTe2 is now the leading candidate. Ideally, the parity of $Delta(k)$ might be […]
