Nonclassical imaging for a quantum search of trapped ions
(American Physical Society, 2004-12-27)
We discuss a simple search problem which can be pursued with different methods, either on a classical or on a quantum basis. The system is represented by a chain of trapped ions. The ion to be searched is a member of that ...
Quantum imaging with incoherent photons
(American Physical Society, 2007-09-28)
We propose a technique to obtain subwavelength resolution in quantum imaging with potentially 100% contrast using incoherent light. Our method requires neither path-entangled number states nor multiphoton absorption. The ...
