Cold Ions and Experimental Quantum Information

Prof. Dr. Ferdinand Schmidt-Kaler , Dr. Rene Gerritsma, Dr. Ulrich Poschinger and PD Dr. Kilian Singer

In Quantum Information Processing, we utilize genuine quantum mechanical effects for novel, up to now inaccessible, physical applications. Superposition of states and entanglement enable the realization of Quantum Computers, transfer of secret information, simulation of complex matter states and improved physical measurements.

In our experiments, we study systems suitable for such future technologies and how to improve them.

Theoretical Quantum Optics and Quantum Information

Prof. Dr. Peter van Loock

The primary goal of the group is to construct and propose feasible implementations of partial and complete protocols in quantum information science (quantum communication and quantum logic). The resources (quantum states) and methods (for manipulating and measuring quantum states) originate from quantum optical methods accessible in the lab today. From a more abstract perspective, we want to simultaneously utilize discrete and continuous variables for coding, communication and information processing.

Experimental Quantum Optics and Quantum Information

Prof. Dr. Patrick Windpassinger

The research group is concerned with the application of cold and ultracold, neutral quantum gases. We are investigating the usage of cold atoms as quantum information storage devices, quantum sensors and building blocks for quantum simulators of solid state systems. To this end, the atoms, which are cooled to temperatures just above absolute zero, are for example stuffed into hollow core optical fibers, arranged into crystal like structures – so called optical lattices – or put even whole experimental apparatuses into drop capsules or onto sounding rockets.

Atomic Tests of Fundamental Symmetries and Small-Scale Multidisciplinary Research

Prof. Dr. Dmitry Budker, Dr. Samer Afach, Dr. Dionysis Antypas, Dr. John Blanchard, Dr. Lykourgos Bougas, Dr. Nathan Leefer, Dr. Arne Wickenbrock

Our research focuses on testing fundamental symmetries of nature in experiments that utilize the methods of atomic, molecular, and optical physics; development of all-optical sensors based on atomic vapors and color centers in diamond; zero- and ultralow-field nuclear magnetic resonance (ZULF NMR). The group's research includes elements of elementary-particle and nuclear physics, solid-state physics, and physical chemistry. For a detailed description of our research, please visit the Budker group web page @ Berkeley.
