Nonclassical imaging for a quantum search of trapped ions Academic Article uri icon


  • Nonclassical imaging technique for a quantum search problem using a chain of trapped ions was investigated. The interference patterns were produced by the light of all emitting ions of the chain at once so that there is a simultaneous contribution of all scatterers to the signal. Quantum interferences allow to increase the parameter space available and improve the precision when a larger number of ions were involved. An interference pattern was obtained even at ion distances smaller than /2 which is the ultimate limit for a classical interference experiment.
