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…
Neural Wavefunctions in Quantum Field Theory I: Asymptotic Freedom
Paulo F. Bedaque, Hersh Kumar, Suryansh Rajawat +1
We present a variational approach to quantum field theory based on wavefunctions parameterized by neural networks. While variational methods have a celebrated history across many f…
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…
Trapped Fermions Through Kolmogorov-Arnold Wavefunctions
Paulo F. Bedaque, Jacob Cigliano, Hersh Kumar +2
We investigate a variational Monte Carlo framework for trapped one-dimensional mixture of spin- fermions using Kolmogorov-Arnold networks (KANs) to construct universal…
Kolmogorov-Arnold Wavefunctions
Paulo F. Bedaque, Jacob Cigliano, Hersh Kumar +2
This work investigates Kolmogorov-Arnold network-based wavefunction ansatz as viable representations for quantum Monte Carlo simulations. Through systematic analysis of one-dimensi…
