Although the quantum fitness landscape is often compatible with greedy algorithms, sometimes greedy algorithms yield poor results, especially for large-dimensional quantum systems.
A quantum control landscape is the expectation value of an observable expressed as a function of the control variables, and the local geometry of the landscape for state-to-state transitions is explored for its implications upon practical searches for optimal controls.
A reexamination of basic Eberly revivals, Berry "quantum fractal" landscapes, and the "quantum carpets" of Schleich and co-workers reveals a simple Farey arithmetic and Cn-group revival structure in one of the earliest quantum wave models, the Bohr rotor.
Though the impression often painted of the research landscape in quantum gravity is an either/or situation between string theory and loop quantum gravity, in reality there are very many more options on the table.
Dominating the landscape of quantum mechanics is Werner Heisenberg's uncertainty principle, which quantifies what can and cannot be known about quantum objects.
Therefore, the diamagnetic shift analysis gives additional information about the local potential landscape in quantum wells.
When classical controller is replaced by a quantum controller, the control landscape becomes much simpler.
Simpson constructed his theory of quantum evolution around geneticist Sewall Wright's (1932) "adaptive landscape" imagery (see Eldredge 2008b, for a discussion of adaptive landscapes and their use in evolutionary theory; Simpson 1944, sometimes shifted to his own terminology, talking about interzonal shifts on an "adaptive grid," but the essence of the imagery is the same as Wright's).
Lithographically defined top gate electrodes imprint in-plane artificial potential landscapes for excitons via the quantum confined Stark effect.
A short list culled from newspaper articles includes Islamic terrorism, China's ascendance, the search for gravity waves, advances in the life sciences, quantum theory and concepts like "remaking the postwar landscape" and harmonizing "the human and natural worlds".
