ffsim: Faster simulation of fermionic quantum circuits
Kevin J. Sung, Inho Choi, Mirko Amico +14
We present ffsim, an open-source software library for fast simulation of fermionic quantum circuits. ffsim exploits conservation of particle number and the z component of spin, sym…
From Promise to Practice: Benchmarking Quantum Chemistry on Quantum Hardware
Osama M. Raisuddin, Haimeng Zhang, Mario Motta +1
We provide a systematic evaluation of the sample-based quantum diagonalization (SQD) method for electronic structure based on the W4-11 thermochemistry dataset, comprising 124 tota…
Improved parameter initialization for the (local) unitary cluster Jastrow ansatz
Wan-Hsuan Lin, Fangchun Liang, Mario Motta +3
The unitary cluster Jastrow (UCJ) ansatz and its variant known as local UCJ (LUCJ) are promising choices for variational quantum algorithms for chemistry due to their combination o…
Uncovering Local Integrability in Quantum Many-Body Dynamics
Oles Shtanko, Derek S. Wang, Haimeng Zhang +4
Interacting many-body quantum systems and their dynamics, while fundamental to modern science and technology, are formidable to simulate and understand. However, by discovering the…
