I like to experiment with the quantum information stored in trapped ions. I lead now a group sharing the same passion. In my previous life, I measured how strong electric fields change the magnetic moment of the electron, studied quantum chaos, ran quantum gates, characterized entangled states, and teleported quantum information over 10 micrometers. Notable current achievements of my group are ultra low-noise ion traps and a Michelson-Morley test for electrons. When not behind a keyboard, I love being outside such as on playgrounds with my daughters or on the water windsurfing.

I like revealing the puzzling nature of quantum systems and enjoy the challenges that trapped ions systems provides. Outside the lab I love to explore the bay area with my family.

The ability to observe and control quantum states (in a lab) is probably the most exciting thing in physics for me. Having spent a PhD and a few Postdoc-years on solid-state spin systems I am very excited to learn about ion surface traps in Berkeley now. I also like racket sports and baking bread.

I work on the ring trap experiment and love the new challenges the geometry provides. I play Ultimate in my free time and watch the Green Bay Packers on Sundays.

I enjoy tackling the technical obstacles to creating a trapped ion quantum processor and currently measure a lot of heating rates. On campus, I volunteer with the Graduate Assembly and the Pi Beta Phi Alumnae Advisory Committee. I love to travel, bake, and explore the Bay area.

I am a graduate student studying surface science with trapped ions, and I'm interested in microfabrication and quantum computation. Outside of the lab I love dancing, swimming in the ocean, and vegetarian cooking.

My interests lie in exploring the nontrivial and often nonintuitive dynamics that can arise in modestly sized but very precisely controlled and manipulated atomic systems. Currently I am working on an emulation of non-classical energy transfer in a spin chain coupled to a mesoscopic bosonic bath, which is difficult or impossible to numerically calculate. Outside of the lab I enjoy long walks in the hills with my 10 year old German shepherd, Lia.

I'm a graduate student, excited to learn about the theory and techniques of ion trapping, along with its applications to quantum information. Outside of the lab, I enjoy playing card/board games and eating.

I love being able to see the effects of quantum mechanics on a tabletop, as well as just learning and discovering how the universe works. I enjoy exploring the bay area, video games, and making lists.

Having previously worked on the local Lorentz invariance experiment, I now spend my time designing an aparatus that will soon shuttle and entangle large chains of ions. Outside the lab I enjoy exploring San Fransisco, watching films, and skiing.

After working years on using AMO techniques to studying plasma physics with a system which usually contains 10^5 to a million charged particles, I decided to switch my interest to ion trap research which involves only a couple or just one charged particle with a very high degree of control and understanding of the properties of the ion.

I spent several years programming classical computers before coming to Berkeley to study quantum computers. I'm most interested in the intersection of computer science with quantum information, and how to realize this in physical systems. I also enjoy some human things, like playing basketball, cooking, and traveling.

After working with solid state systems during my PhD I am excited to work with trapped ions. Regardless of implementation, I am interested in building and using large coherent quantum systems for computation, communication, and sensing. Outside the lab I am usually climbing, cooking, or eating.
