We propose an exact expression for the energy eigenvalues of the pure λx2m quantum anharmonic oscillators. The only information needed for the purpose is K0(m,n), which is the first term of strong-coupling\nexpansion for oscillator with potential λx2m for the nth excited state. We then ...
ACCORDING to quantum mechanics, an oscillator possesses a definite zero-point energy of vibration, and an attempt has been made to express this result directly in terms of some general principle. It has been found that the result may be deduced from the uncertainty principle, in view of the ...
The energy levels of a single quantum quartic oscillator and those of a pair of coupled quartic anharmonic oscillators are investigated. Expansions for the energy levels are obtained for different energy regimes and numerical results for a variety of conditions are given. A WKB analysis is included...
As in Boyer's argument, no explicit assumption of quantum mechanics is introduced. We discuss the relation of our results to the analysis of Planck and Einstein which led to the notion of the quantized radiation field. We then inquire into the discrete or continuous behavior of the energy and...
We propose a scheme to add/subtract excitations to/from an arbitrary quantum state or the harmonic oscillator. The method displaces the photon-number distribution and leaves its shape unchanged for a wide range of displacements. Mathematically this is realized by the action of phase operators of ...

In the near future, one of the major challenges in the realization of large-scale quantum computers operating at low temperatures is the management of harmful heat loads owing to thermal conduction of cabling and dissipation at cryogenic components. This
