Long distance manipulation of a levitated nanoparticle in high vacuum [PDF]
, 2015 Accurate delivery of small targets in high vacuum is a pivotal task in many branches of science and technology. Beyond the different strategies developed for atoms, proteins, macroscopic clusters and pellets, the manipulation of neutral particles over ...

Independent trapping and manipulation of microparticles using dexterous acoustic tweezers [PDF]
, 2014 An electronically controlled acoustic tweezer was used to demonstrate two acoustic manipulation phenomena: superposition of Bessel functions to allow independent manipulation of multiple particles and the use of higher-order Bessel functions to trap ...

Localized optical manipulation in optical ring resonators
Optics Express, 2015 We propose a tunable optical trapping system for nanoparticles based on generating standing wave by coupling two coherent beams into a ring resonator in opposite directions, respectively. The distributions of the mode field excited in three types of the ring-resonators-based trapping systems (microring, microdisk and slot ring) and the corresponding ...

Optical Trapping and Manipulation [PDF]
, 2010 A number of applications of microsystem technology require manipulation with high accuracy. Microreactors and microdiagnostic devices can be easily constructed with millimetre accuracy [1], but micrometre precision appears also to be realistic (see for example Fig. 3 below).

Loss-tolerant operations in parity-code linear optics quantum computing [PDF]
, 2007 A heavy focus for optical quantum computing is the introduction of error-correction, and the minimisation of resource requirements. We detail a complete encoding and manipulation scheme designed for linear optics quantum computing, incorporating scalable

Analysis for practical realization of number-state manipulation by number-sum Bell measurement with linear optics [PDF]
, 2004 We analyze the linear optical realization of number-sum Bell measurement and number-state manipulation by taking into account the realistic experimental situation, specifically imperfectness of single-photon detector.
