Our analysis begins with the definition of a general form for the quantum state of a PCET system and its quantum equations of motion.
In fact, Aspelmeyer, Oskar Painter of the California Institute of Technology in Pasadena, and colleagues have managed to use laser light to "cool" a vibrating beam to the lowest energy state possible, the so-called quantum ground state, a key step toward achieving more complex quantum states of motion, as they reported 6 October in Nature.
Recall our quantum equations of motion for the microwave cavity field (47).
The ability to produce quantum states of motion could lead to tiny devices that meld quantized vibrations, or "phonons," with electronic and optical signals.
For example, this methodology allows for the interpretation of the trajectories orthogonal to constant surfaces, by cancelling the Laplacian of the wave fronts ∇ r 2S r, t) = 0, which are obtained from eqs. (8) and (9) as the quantum equation of motion: ∂ p ∂ t = − ∇ r V Q r + V r (11).
O'Connell and his colleagues used the qubit to demonstrate that they had reached the true quantum ground state of motion for the first time.
But to observe any quantum effects, the whole chip had to be cooled to a temperature so low that the resonator would occupy its lowest energy state (the quantum ground state of motion).
Because of the need to reduce Copenhagen's indeterminacy for quantum phenomena, i.e., by associating it the quantum description of "Newtonian" forms of motion, though by preserving probability densities, quantum averages, etc., the so-called "minimalist" quantum theory may be formulated following the Bohm quantum mechanical program as follows.
How do the (quantum and classical) laws of motion and the statistical mechanics of complex assemblies constrain the structure and function of PCET assemblies?
