Coherent quantum optical control with subwavelength resolution. Physical Review Letters 100(9): 093005.1079-71140031-9007http://nrs.harvard.edu/urn-3:HUL.InstRepos:7983349We suggest a new method for quantum optical control with nanoscale resolution. Our method allows for coherent far-field manipulation of individual quantum systems with spatial selectivity that is not limited by the wavelength of radiation and can, in principle, approach a few nanometers. The selectivity is enabled by the nonlinear atomic response, under the conditions of electromagnetically induced transparency, to a control beam with intensity vanishing at a certain location. Practical performance of this technique and its potential applications to quantum information science with cold atoms, ions, and solid-state qubits are discussed.en-USquantum physicsmesoscale physicsnanoscale physicsother condensed matterJournal Article2012-01-2010.1103/PhysRevLett.100.093005
