Global permutationally invariant potential energy surface for ozone forming reaction.
We constructed new global potential energy surface for O + O2 → O3 reaction. It is based on high level electronic structure theory calculations and employs fitting by permutationally invariant polynomial functions. This method of surface construction takes full advantage of permutation symmetry of three O nuclei and allows reducing dramatically the number of ab initio data points needed for acc...
متن کاملPermutationally Invariant Polynomial Basis for Molecular Energy Surface Fitting via Monomial Symmetrization.
We describe a procedure to develop a fitting basis for molecular potential energy surfaces (PESs) that is invariant with respect to permutation of like atoms. The method is based on a straightforward symmetrization of a primitive monomial basis and illustrated for several classes of molecules. A numerically efficient method to evaluate the resulting expression for the PES is also described. The...
متن کاملPermutationally invariant quantum tomography.
We present a scalable method for the tomography of large multiqubit quantum registers. It acquires information about the permutationally invariant part of the density operator, which is a good approximation to the true state in many relevant cases. Our method gives the best measurement strategy to minimize the experimental effort as well as the uncertainties of the reconstructed density matrix....
متن کاملPermutationally Invariant Codes for Quantum Error Correction
A permutationally invariant n-bit code for quantum error correction can be realized as a subspace stabilized by the non-Abelian group Sn. The code corresponds to bases for the trivial representation, and all other irreducible representations, both those of higher dimension and orthogonal bases for the trivial representation, are available for error correction. A number of new (non-additive) cod...
متن کاملAccurate global potential energy surface and reaction dynamics for the ground state of HgBr2.
A global potential energy surface (PES) for the (1)A' ground state of HgBr(2) has been constructed in order to determine the rate constants for atmospherically important reactions involving mercury and bromine. The total energy of HgBr(2) was calculated by the multireference configuration interaction level of theory with series of correlation consistent basis sets up to quadruple-zeta quality w...
