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…
