ScholarBank@NUS Repository. https://doi.org/10.1103/PhysRevLett.97.023602||Abstract:||The novel experimental realization of four-level optical quantum systems (ququarts) is presented. We exploit the polarization properties of the frequency nondegenerate biphoton field to obtain such systems. A simple method that does not rely on am interferometer is used to generate and measure the sequence of states that can be used in quantum key distribution protocol. © 2006 The American Physical Society.||Source Title:||Physical Review Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/97768||ISSN:||00319007||DOI:||10.1103/PhysRevLett.97.023602|
