Book Description
Now in an updated second edition, this classroom-tested textbook introduces and summarizes the latest models and skills required to design and optimize nanomechanical resonators, taking a top-down approach that uses macroscopic formulas to model the devices. The authors cover the electrical and mechanical aspects of nanoelectromechanical system (NEMS) devices in six expanded and revised chapters on lumped-element model resonators, continuum mechanical resonators, damping, transduction, responsivity, and measurements and noise. The applied approach found in this book is appropriate for engineering students and researchers working with micro and nanomechanical resonators.

Book Description
In the recent decade, tremendous amount of work has been done to probe the quantum properties of macroscopic mechanical devices. As a first step, researchers are racing to cool "large" mechanical objects to their quantum ground states. In this dissertation, I will describe the physics of the resolved sideband cooling technique used by our group to cool a nanomechanical resonator (NR) to its motional ground state. To this end we have fabricated high-Q NRs parametrically coupled to superconducting microwave coplanar waveguides (SR). We have been able to cool the motion of a 6.3 MHz nanomechanical resonator coupled to a 7.5 GHz superconducting resonator. Starting from a thermal occupation of ~500 quanta, we have observed mechanical occupation factors as low as 3.8 +/- 1.2 and expect the mechanical motion to be found with probability 0.21 in the quantum ground state of motion. I will describe the factors which are limiting further cooling and progress towards colder states of motion. By measuring differences in up and down-conversion of microwave photons in a process analogous to Raman scattering, we expect to observe fundamental quantum behavior of the nanomechanics. Furthermore, using a backaction evading configuration for our system, we should in principle be able to squeeze one of the quadratures of motion of the NR below the standard quantum limit. The results of this dissertation and the future works indicate the path forward for future experiments that prepare, detect and manipulate non-classical states of NR motion.

Book Description
Adopting a cross-disciplinary approach, the review character of this monograph sets it apart from specialized journals. The editor is advised by a first-class board of international scientists, such that the carefully selected and invited contributions represent the latest and most relevant findings. The resulting review enables both researchers and newcomers in life science, physics, and chemistry to access the most important results in this field, using a common language.

Book Description
The counter-intuitive aspects of quantum physics have been long illustrated by thought experiments, from Einstein's photon box to Schrödinger's cat. These experiments have now become real, with single particles - electrons, atoms, or photons - directly unveiling the strange features of the quantum. State superpositions, entanglement and complementarity define a novel quantum logic which can be harnessed for information processing, raising great hopes for applications. This book describes a class of such thought experiments made real. Juggling with atoms and photons confined in cavities, ions or cold atoms in traps, is here an incentive to shed a new light on the basic concepts of quantum physics. Measurement processes and decoherence at the quantum-classical boundary are highlighted. This volume, which combines theory and experiments, will be of interest to students in quantum physics, teachers seeking illustrations for their lectures and new problem sets, researchers in quantum optics and quantum information.

Book Description
This book is an up-to-date introduction to the quantum theory of measurement. Although the main principles of the field were elaborated in the 1930s by Bohr, Schrödinger, Heisenberg, von Neuman, and Mandelstam, it was not until the 1980s that technology became sufficiently advanced to allow its application in real experiments. Quantum measurement is now central to many ultra-high technology developments, such as "squeezed light," single atom traps, and searches for gravitational radiation. It is also considered to have great promise for computer science and engineering, particularly for its applications in information processing and transfer. The book begins with a brief introduction to the relevant theory and goes on to discuss all aspects of the design of practical quantum measurement systems.
