Aaron D. O'Connell
Aaron Douglas O'Connell (born March 5, 1981, in Allentown, Pennsylvania) is an American experimental quantum physicist. Early life and education O'Connell was born in Allentown, Pennsylvania on March 5, 1981. In 2005, he received his bachelor's degree from Eckerd College in St. Petersburg, Florida. In 2010, he received his Ph.D. in physics from the University of California, Santa Barbara. Career While working under Andrew N. Cleland and John M. Martinis at the University of California, Santa Barbara, he created the world's first quantum machine. In particular, he was able to transfer the quantum state of a superconducting quantum bit, a device used in quantum computation, to the motional state of a macroscopic mechanical resonator. His measurements of the quantum machine constitute the first direct observations of quantized behavior in the motion of a visible object and led the journal ''Science'' to honor his work as the Breakthrough of the Year in 2010.

Resonator
A resonator is a device or system that exhibits resonance or resonant behavior. That is, it naturally oscillates with greater amplitude at some frequencies, called resonant frequencies, than at other frequencies. The oscillations in a resonator can be either electromagnetic or mechanical (including acoustic). Resonators are used to either generate waves of specific frequencies or to select specific frequencies from a signal. Musical instruments use acoustic resonators that produce sound waves of specific tones. Another example is quartz crystals used in electronic devices such as radio transmitters and quartz watches to produce oscillations of very precise frequency. A cavity resonator is one in which waves exist in a hollow space inside the device. In electronics and radio, microwave cavities consisting of hollow metal boxes are used in microwave transmitters, receivers and test equipment to control frequency, in place of the tuned circuits which are used at lowe ...

Motion (physics)
In physics, motion is when an object changes its position with respect to a reference point in a given time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and frame of reference to an observer, measuring the change in position of the body relative to that frame with a change in time. The branch of physics describing the motion of objects without reference to their cause is called ''kinematics'', while the branch studying forces and their effect on motion is called '' dynamics''. If an object is not in motion relative to a given frame of reference, it is said to be ''at rest'', ''motionless'', ''immobile'', '' stationary'', or to have a constant or time-invariant position with reference to its surroundings. Modern physics holds that, as there is no absolute frame of reference, Isaac Newton's concept of '' absolute motion'' cannot be determined. Everything in the universe can be considered to be in motion. Motion applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
