Mechanical resonators in the quantum regime
The superconducting quantum circuits group at UC Santa Barbara has spent the past ten years developing superconducting and nanomechanical systems for fundamental experiments in quantum mechanics; our ultimate goal is to build a superconducting quantum computer. The Josephson junction, a fundamental superconducting device analogous to a transistor, provides an extremely nonlinear electrical circuit element that can be used as an “electronic atom”, enabling the detection and manipulation of single quanta of energy, as well as demonstrations of simple quantum algorithms. We have used this device to demonstrate full quantum control over microwave-frequency photons in electromagnetic resonators, and more recently demonstrate ground-state cooling of a macroscopic mechanical resonator as well as manipulate individual phonons, the quanta of mechanical vibrations.

Aalto physics colloquium is a high-level colloquium series covering all branches of physics in the Aalto university. Its aim is to invite high-level physicists from all around the world to tell about their research. The lectures are targeted to all physicists and those interested in physics. Entrance to the events is free of charge. Colloquia are organized approximatively once a month during the term time and the invitation responsibility circulates between all physics professors on the Aalto campus. The colloquium is funded by the Aalto department of Applied Physics, Academy of Finland center of excellence COMP (Computational Nanoscience) and Low Temperature Laboratory.
Aalto University is created through a merger between the Helsinki School of Economics, the University of Art and Design Helsinki and the Helsinki University of Technology. Aalto contains the top Finnish condensed matter physics research units, with specialization especially in materials research, optics, low temperature physics, nanophysics, medical physics and energy technology.
New: It is possible for the students to get study credits from the colloquia. For the rules, check this page
