Simulating two-dimensional lattice QED with matter fields.

Qudit Quantum Computing Breaks New Ground in Gauge Theory

Researchers from the University of Innsbruck and the University of Waterloo have achieved a breakthrough in quantum computing by using qudits (quantum units with multiple values) instead of traditional qubits to efficiently simulate quantum electrodynamics in two dimensions, demonstrating magnetic field interactions between particles and opening new possibilities for solving previously intractable problems in particle physics.

Quantum research breakthrough uses synthetic dimensions to efficiently process quantum information

A new study opens the door to cutting-edge solutions that could contribute to the realization of a system capable of processing quantum information in a simple yet powerful way. The work presents a method for manipulating the photonic states of light in a never-before-seen way, offering greater control over the evolution of photon propagation. This control makes it possible to improve the detection and number of photon coincidences, as well as the efficiency of the system.
