The purpose of the Quantum Coherence Lab (QCL) at HUJI is to explore the phenomena of macroscopic quantum coherence and decoherence. We study superconducting Josephson circuits, in which macroscopic physical quantities such as magnetic flux behave quantum mechanically. We also study implementations of macroscopic quantum coherence in slow and stored light in atomic ensembles, manipulating and storing non-trivial patterns of light and subsequently retrieving them.

The study of decoherence, in addition to showcasing fundamental physics, is crucial in overcoming the main bottleneck in the field of quantum computation and quantum information processing.
