JILA scientists conduct innovative research in quantum information with a goal of better understanding the tiny, cold world where the laws of quantum mechanics apply. This research encompasses the exciting new research areas of new quantum technologies, quantum simulation, and quantum computing. Research in new quantum technologies features investigations into hybrid quantum systems that probe the quantum interface between light and micro mechanical motion as well as the creation and investigation of trapped single neutral atoms.

In quantum simulation, JILA scientists have built two quantum simulators that probe the quantum mechanical behavior of cool, lattice-confined Sr atoms and ultracold KRb molecules. The new Sr-lattice clock simulator is being used to investigate quantum magnetism and other quantum behaviors. The KRb simulator is also being using to probe quantum magnetism and exotic quantum behaviors that manifest at ultralow temperatures. In the field of quantum computing, researchers are investigating multidimensional scans of the quantum states of microwave fields and quantum synchronization. JILA scientists have also devised an innovative model of a quantum computer based on Sr atoms in a lattice.

The Institute’s research in quantum information supports its work in atomic, molecular, and optical physics, nanoscience, and precision measurement. Together, JILA’s quantum information experts are looking for answers to profound questions in this new frontier of physics:
