Authors: Goicoechea, Javier R.; Lique, Francois; Santa-Maria, Miriam G. Journal: ASTRONOMY & ASTROPHYSICS Publication date: 2022/01/27 DOI: 10.1051/0004-6361/202142210 Abstract: Hydrogen cyanide (HCN) is considered a good tracer of the dense molecular gas that serves as fuel for star formation. However, recent large-scale surveys of giant molecular clouds (GMCs) have detected extended HCN rotational line emission [...]

Quantum Fourier analysis for multivariate functions and applications to a class of Schrodinger-type partial differential equations

2023-02-21T13:37:18+01:00Tags: , , |

Authors: Garcia-Molina, Paula; Rodriguez-Mediavilla, Javier; Jose Garcia-Ripoll, Juan Journal: PHYSICAL REVIEW A Publication date: 2022/01/31 DOI: 10.1103/PhysRevA.105.012433 Abstract: In this work we develop a highly efficient representation of functions and differential operators based on Fourier analysis. Using this representation, we create a variational hybrid quantum algorithm to solve static, Schrodinger-type, Hamiltonian partial differential equations (PDEs), [...]
