Experimental Implementation of Projective Measurement in Bell Basis
arXiv:0801.4098 · doi:10.1016/j.jmr.2009.02.013
Abstract
A scheme for direct projection of a quantum state on Bell states is described. The method is based on constructing an average Hamiltonian with Bell eigenstates and then, projecting the state on these eigenstates. The projection is performed by adding the results of a direct and time-reversed evolution. Experimental demonstration is shown for pairs of dipolar-coupled nuclear spins.
