Natural orbitals and sparsity of quantum mutual information
Leonardo Ratini, Chiara Capecci, Leonardo Guidoni
Natural orbitals, defined in electronic structure and quantum chemistry as the (molecular) orbitals diagonalizing the one-particle reduced density matrix of the ground state, have…
Optimization strategies in WAHTOR algorithm for quantum computing empirical ansatz: a comparative study
Leonardo Ratini, Chiara Capecci, Leonardo Guidoni
By exploiting the invariance of the molecular Hamiltonian by a unitary transformation of the orbitals it is possible to significantly shorter the depth of the variational circuit i…
Pulse variational quantum eigensolver on cross-resonance based hardware
Daniel J. Egger, Chiara Capecci, Bibek Pokharel +4
State-of-the-art noisy digital quantum computers can only execute short-depth quantum circuits. Variational algorithms are a promising route to unlock the potential of noisy quantu…
