Alexander Guttridge

Dr. Alexander Guttridge is a Royal Society University Research Fellow in the Department of Physics at Durham University. His experimental research focuses on ultracold quantum systems, specializing in Rydberg molecules and optical tweezer manipulation for quantum information applications. He is an active member of Durham's Quantum Light and Matter research group, contributing to cutting-edge advancements in atomic and molecular physics.

Guttridge's research centers on quantum control of individual molecules using optical tweezer arrays, with emphasis on Rydberg interactions, entanglement preservation, and quantum state transfer. His work explores two-species systems (particularly cesium and ytterbium compounds) to investigate novel quantum phenomena including charge-dipole blockade, ultralong-range molecular bonds, and Feshbach resonances. This research bridges atomic physics, quantum optics, and quantum computing with direct implications for quantum simulation and information processing.

His 12 publications from 2018-2025 reveal a clear progression from foundational spectroscopy of CsYb molecules toward sophisticated quantum control techniques. Key trends include the development of optical tweezer assembly methods for Rydberg molecules, demonstration of long-lived entanglement in magic-wavelength traps, and innovations in quantum state transfer through noise cancellation. These works consistently advance experimental capabilities in ultracold molecular physics while targeting quantum computing applications.
