Ground- and excited-state energies extraction via Trotterization on IBM quantum computers
Fernando Espinoza-Ortiz, Chungwei Lin, Chih-Chun Chien
We implement the Hadamard test with Trotterized time-evolution operators on IBM quantum computers to simultaneously extract ground- and excited-state energies of the transverse fie…

Third quantization with Hartree approximation for open-system bosonic transport
Fernando Espinoza-Ortiz, Chih-Chun Chien
The third quantization (3rd Q) for bosons provides the exact steady-state solution of the Lindblad equation with quadratic Hamiltonians. By decomposing the interaction of the Bose…
