Tequila: A platform for rapid development of quantum algorithms
Jakob S. Kottmann, Sumner Alperin-Lea, Teresa Tamayo-Mendoza +15
Variational quantum algorithms are currently the most promising class of algorithms for deployment on near-term quantum computers. In contrast to classical algorithms, there are al…
A posteriori corrections to the Iterative Qubit Coupled Cluster method to minimize the use of quantum resources in large-scale calculations
Ilya G. Ryabinkin, Artur F. Izmaylov, Scott N. Genin
The iterative qubit coupled cluster (iQCC) method is a systematic variational approach to solve the electronic structure problem on universal quantum computers. It is able to use a…
How to define quantum mean-field solvable Hamiltonians using Lie algebras
Artur F. Izmaylov, Tzu-Ching Yen
Necessary and sufficient conditions for quantum Hamiltonians to be exactly solvable within mean-field theories have not been formulated so far. To resolve this problem, first, we d…
Cartan sub-algebra approach to efficient measurements of quantum observables
Tzu-Ching Yen, Artur F. Izmaylov
An arbitrary operator corresponding to a physical observable cannot be measured in a single measurement on currently available quantum hardware. To obtain the expectation value of…
On the order problem in construction of unitary operators for the Variational Quantum Eigensolver
Artur F. Izmaylov, Manuel Díaz-Tinoco, Robert A. Lang
One of the main challenges in the Variational Quantum Eigensolver (VQE) framework is construction of the unitary transformation. The dimensionality of the space for unitary rotatio…
Unitary transformation of the electronic Hamiltonian with an exact quadratic truncation of the Baker-Campbell-Hausdorff expansion
Robert A. Lang, Ilya G. Ryabinkin, Artur F. Izmaylov
Application of current and near-term quantum hardware to the electronic structure problem is highly limited by qubit counts, coherence times, and gate fidelities. To address these…
