Experimental test of coherent betatron resonance excitations

Ion Resonance Instability in a Modified Betatron Accelerator

Experimental Test of Complementarity by Nuclear Magnetic Resonance Techniques

We have tested complementarity for the ensemble-averaged spin states of nuclei C in the molecule of 13CHCl3 by the use of the spin states of another nuclei H as the path marker. It turns out that the wave-particle duality holds when one merely measures the probability density of quantum states, and that the waveand particle-like behavior is simultaneously observed with the help of measuring pop...

Coherent storage of microwave excitations in rare-earth nuclear spins.

Interfacing between various elements of a computer--from memory to processors to long range communication--will be as critical for quantum computers as it is for classical computers today. Paramagnetic rare-earth doped crystals, such as Nd(3+):Y2SiO5(YSO), are excellent candidates for such a quantum interface: they are known to exhibit long optical coherence lifetimes (for communication via opt...

Coherent optical control of electronic excitations in functionalized semiconductor nanostructures

The feasibility of creating and manipulating coherent quantum states on surfaces of functionalized semiconductor nanostructures is computationally investigated. Quantum dynamics simulations of electron-hole transfer between catechol molecules adsorbed on TiO2 -anatase nanostructures under cryogenic and vacuum conditions indicate that laser induced coherent excitations can be prepared and manipu...

Coherent selection of invisible high-order electromagnetic excitations

Far-field spectroscopy and mapping of electromagnetic near-field distribution are the two dominant tools for analysis and characterization of the electromagnetic response in nanophotonics. Despite the widespread use, these methods can fail at identifying weak electromagnetic excitations masked by stronger neighboring excitations. This is particularly problematic in ultrafast nanophotonics, incl...
