Quantum simulation of molecular excited-state manifolds and energies using the TEPID-ADAPT-VQE algorithm
Jason Saroni, Bharath Sambasivam, Ayush Asthana +1
The simulation of molecular excited states is a key challenge in quantum chemistry and a promising application for quantum computing. In this work, we investigate the efficacy of t…
On the generalized eigenvalue problem in subspace-based excited state methods for quantum computers
Prince Frederick Kwao, Srivathsan Poyyapakkam Sundar, Brajesh Gupt +1
Solving challenging problems in quantum chemistry is one of the most promising applications of quantum computers. Within the quantum algorithms proposed for problems in excited sta…
Exact and Tunable Quantum Krylov Subspaces via Unitary Decomposition
Ayush Asthana
Quantum Krylov subspace methods can extract ground and excited states by diagonalizing the Hamiltonian in a compact variational space. In practice, these spaces are almost always g…
Chemically decisive benchmarks on the path to quantum utility
Srivathsan Poyyapakkam Sundar, Vibin Abraham, Bo Peng +1
Progress towards quantum utility in chemistry requires not only algorithmic advances, but also the identification of chemically meaningful problems whose electronic structure funda…
