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 daughter 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.

I find it fascinating that we can manipulate single ions in the lab. I like to learn about new ways to measure things more precisely and explore methods to use quantum mechanics to simulate complex systems. Outside the lab, I like sailing.

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.

What I love about ion trapping is the multitude of things we learn about: quantum mechanics, electronics, optics, micro-fabrication and lasers. When you see ions on the camera reacting to your actions its due to the combination of all of these that you can run your experiment. Most of my free time I spend practicing and teaching the martial arts Taekwondo and Yongmudo.

I am a grad student currently working on quantum simulation. I enjoy cycling, cooking, and long walks on the beach.

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.

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'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.
