A solution for infinite variance problem of fermionic observables
Hyunwoo Oh, Andrei Alexandru, Paulo F. Bedaque +1
Fermionic Monte Carlo calculations with continuous auxiliary fields often encounter infinite variance problem from fermionic observables. This issue renders the estimation of obser…
Fuzzy gauge theory for quantum computers
Andrei Alexandru, Paulo F. Bedaque, Andrea Carosso +3
Continuous gauge theories, because of their bosonic degrees of freedom, have an infinite-dimensional local Hilbert space. Encoding these degrees of freedom on qubit-based hardware…
Simulating Nelsonian Quantum Field Theory
Andrea Carosso
We describe the picture of physical processes suggested by Edward Nelson's stochastic mechanics when generalized to quantum field theory regularized on a lattice, after an introduc…
On the Infinite Variance Problem in Fermion Models
Andrei Alexandru, Paulo Bedaque, Andrea Carosso +1
Monte Carlo calculations of fermionic systems with continuous auxiliary fields frequently suffer from a diverging variance. If a system has the infinite variance problem, one canno…
Qubitization strategies for bosonic field theories
Andrei Alexandru, Paulo F. Bedaque, Andrea Carosso +2
Quantum simulations of bosonic field theories require a truncation in field space to map the theory onto finite quantum registers. Ideally, the truncated theory preserves the symme…
Quantization: History and Problems
Andrea Carosso
In this work, I explore the concept of quantization as a mapping from classical phase space functions to quantum operators. I discuss the early history of this notion of quantizati…
