Post-Optimization Subspace Corrections to Quantum Ansätze
Prince Frederick Kwao, Bharath Sambasivam, Jason Saroni +3
Circuit depth and measurement count are the main limitations for chemical applications of the leading variational quantum algorithms on quantum computers. We show that both resourc…
Molecular Excited States using Quantum Subspace Methods: Accuracy, Resource Reduction, and Error-Mitigated Hardware Implementation of q-sc-EOM
Srivathsan Poyyapakkam Sundar, Prince Frederick Kwao, Alexey Galda +1
Problems in quantum chemical simulations, especially achieving accurate excited-state potential energy surfaces, are among the primary applications to achieve quantum utility. On n…
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…
