Measuring all compatible operators in one series of a single-qubit measurements using unitary transformations
Tzu-Ching Yen, Vladyslav Verteletskyi, Artur F. Izmaylov
The Variational Quantum Eigensolver approach to the electronic structure problem on a quantum computer involves measurement of the Hamiltonian expectation value. Formally, quantum…
Unitary partitioning approach to the measurement problem in the Variational Quantum Eigensolver method
Artur F. Izmaylov, Tzu-Ching Yen, Robert A. Lang +1
To obtain estimates of electronic energies, the Variational Quantum Eigensolver (VQE) technique performs separate measurements for multiple parts of the system Hamiltonian. Current…
Measurement Optimization in the Variational Quantum Eigensolver Using a Minimum Clique Cover
Vladyslav Verteletskyi, Tzu-Ching Yen, Artur F. Izmaylov
Solving the electronic structure problem using the Variational Quantum Eigensolver (VQE) technique involves measurement of the Hamiltonian expectation value. Current hardware can p…
Exact and approximate symmetry projectors for the electronic structure problem on a quantum computer
Tzu-Ching Yen, Robert A. Lang, Artur F. Izmaylov
Solving the electronic structure problem on a universal-gate quantum computer within the variational quantum eigensolver (VQE) methodology requires constraining the search procedur…
On construction of projection operators
Artur F. Izmaylov
The problem of construction of projection operators on eigen-subspaces of symmetry operators is considered. This problem arises in many approximate methods for solving time-indepen…
Search for neutral-current induced single photon production at the ND280 near detector in T2K
K. Abe, R. Akutsu, A. Ali +314
Neutrino neutral-current induced single photon production is a sub-leading order process for accelerator-based neutrino beam experiments including T2K. It is, however, an important…
