Ratcheting up energy by means of measurement
L. S. Schulman, B. Gaveau
The destruction of quantum coherence can pump energy into a system. For our examples this is paradoxical since the destroyed correlations are ordinarily considered negligible. Math…
Limits of fractality: Zeno boxes and relativistic particles
L. S. Schulman
Physical fractals invariably have upper and lower limits for their fractal structure. Berry has shown that a particle sharply confined to a box has a wave function that is fractal…
Zeno dynamics yields ordinary constraints
P. Facchi, S. Pascazio, A. Scardicchio +1
The dynamics of a quantum system undergoing frequent measurements (quantum Zeno effect) is investigated. Using asymptotic analysis, the system is found to evolve unitarily in a pro…
Berry phase from a quantum Zeno effect
P. Facchi, A. G. Klein, S. Pascazio +1
We exhibit a specific implementation of the creation of geometrical phase through the state-space evolution generated by the dynamic quantum Zeno effect. That is, a system is guide…
Bounds on Decoherence and Error
L. Schulman
When a confined system interacts with its walls (treated quantum mechanically), there is an intertwining of degrees of freedom. We show that this need not lead to entanglement, hen…
