Hamiltonian spectra in quantum computers through the generalized eigenvalue method
Valery Simonyan, Greg Ridgway, Paulo Bedaque
Quantum computers can generate real-time correlators of field theories. By adapting the generalized eigenvalue problem to these correlators, energy eigenvalues can be extracted dir…

Quantum computation of mass gap in an asymptotically free theory
Paulo F. Bedaque, Edison M. Murairi, Gautam Rupak +1
In relativistic field theories, the mass spectrum is given by the difference between the energy of the vacuum and the excited states. Near the continuum limit, the cancellation bet…
