31. Non-Compact Variable Formalism for Quantum Simulations of Lattice Gauge Theories

Emanuele Mendicelli (University of Liverpool (United Kingdom))

Simulating lattice gauge theories on quantum computers presents unique challenges driving the development of novel theoretical frameworks. The orbifold lattice formulation offers a scalable framework for quantum simulations of lattice gauge theories. The corresponding quantum circuits can be constructed explicitly, and the computational cost grows polynomially with the number of qubits....

32. Quantum Algorithm for QED

The general simulation of Quantum Field Theory scales exponentially with the spatial volume, which makes the sizable computation possible only through the quantum computer. The standard quantum algorithm for the scalar field theory has long been developed, where the scalar field is simple enough to admit an obviously optimal qubit approximation to the continuum theory. When extending to the...

33. Higgs-like phase transitions, nonperturbatively

Dr Oliver Gould (University of Nottingham)

In the study of cosmological phase transitions, even apparently weakly coupled theories develop strongly coupled sectors. For static equilibrium quantities, lattice and effective field theory methods have been developed to tackle this which are able to yield unambiguously correct results up to small errors. For real-time quantities, the problem is more complicated. In this talk, I will review...
