Trapped ion quantum hardware demonstration of energy calculations using a multireference unitary coupled cluster ansatz: application to the BeH2 insertion problem
Palak Chawla, Disha Shetty, Peniel Bertrand Tsemo +5
In this study, we employ the variational quantum eigensolver algorithm with a multireference unitary coupled cluster ansatz to report the ground state energy of the BeH2 molecule i…
Quantum annealing eigensolver as a NISQ era tool for probing strong correlation effects in quantum chemistry
Aashna Anil Zade, Kenji Sugisaki, Matthias Werner +6
The quantum-classical hybrid variational quantum eigensolver (VQE) algorithm is arguably the most popular noisy intermediate-scale quantum (NISQ) era approach to quantum chemistry.…
Dual Exponential Coupled Cluster Theory: Unitary Adaptation, Implementation in the Variational Quantum Eigensolver Framework and Pilot Applications
Dipanjali Halder, V. S. Prasannaa, Rahul Maitra
In this paper, we have developed a unitary variant of a double exponential coupled cluster theory, which is capable of mimicking the effects of connected excitations of arbitrarily…
