Quantum self-consistent equation-of-motion method for computing molecular excitation energies, ionization potentials, and electron affinities on a quantum computer
Ayush Asthana, Ashutosh Kumar, Vibin Abraham +8
Near-term quantum computers are expected to facilitate material and chemical research through accurate molecular simulations. Several developments have already shown that accurate…
Minimizing state preparation times in pulse-level variational molecular simulations
Ayush Asthana, Chenxu Liu, Oinam Romesh Meitei +3
Quantum simulation on NISQ devices is severely limited by short coherence times. A variational pulse-shaping algorithm known as ctrl-VQE was recently proposed to address this issue…
Accurate quantum simulation of molecular ground and excited states with a transcorrelated Hamiltonian
Ashutosh Kumar, Ayush Asthana, Conner Masteran +5
NISQ era devices suffer from a number of challenges like limited qubit connectivity, short coherence times and sizable gate error rates. Thus, quantum algorithms are desired that r…
