Introduction to Quantum Computing and Lattice Gauge Theory
The pursuit of advanced computing power and efficient tools has led scientists to explore the realm of quantum computers, which leverage the unique properties of matter, such as superposition and entanglement, to perform complex operations. A research team from the University of Trento’s Department of Physics had the opportunity to collaborate with Google‘s Quantum Artificial Intelligence Lab, utilizing their powerful quantum computers to conduct a study on confinement in lattice gauge theory. This research has been published in Nature Physics, highlighting the potential of quantum simulators in addressing phenomena that are not yet fully understood.
The study focused on gauge theories, which describe the fundamental forces in the standard model of particle physics and play a crucial role in condensed matter physics. The constituents of gauge theories, including charged matter and electric gauge fields, are governed by local gauge constraints, leading to key phenomena that require further investigation. Quantum simulators offer a promising solution, as they can process complex systems that conventional computers struggle to handle. The research team, led by Professor Philipp Hauke, chose to explore the question of how electrons, positrons, and quarks interact to form particles and matter, using lattice gauge theory as their framework.
The collaboration between the University of Trento and Google’s Quantum Artificial Intelligence Lab was made possible through a call for projects launched by Google in 2019. The University of Trento was among the eight winners worldwide, and the only institution in the European Union, to be selected for this opportunity. The research team developed an algorithm that was sent to Google’s quantum computers, which performed the computations remotely. These quantum supercomputers use the quantum properties of matter to describe quantum objects in a natural way, surpassing the capabilities of classical “bits” based on binary opposition.
The potential of quantum computers is significant, as they can process an exponentially greater number of particles compared to classical instruments. However, achieving this goal requires working at the interface between fundamental physics and engineering. The research team’s work is located at this intersection, with implications for both theoretical and experimental physics. In the future, this research could have various applications, such as studying new materials in the industrial sector or analyzing chemical compounds in the pharmaceutical sector.
