Hamiltonian simulation in the low-energy subspace
Burak Şahinoğlu, Rolando D. Somma
We study the problem of simulating the dynamics of spin systems when the initial state is supported on a subspace of low energy of a Hamiltonian . This is a central problem in p…

Operator Sampling for Shot-frugal Optimization in Variational Algorithms
Andrew Arrasmith, Lukasz Cincio, Rolando D. Somma +1
Quantum chemistry is a near-term application for quantum computers. This application may be facilitated by variational quantum-classical algorithms (VQCAs), although a concern for…
