Reversibility of dynamics and multiple-quantum coherences
A. K. Khitrin
In spin systems, the decay of the Loschmidt echo in the time-reversal experiment (evolution, perturbation, time-reversed evolution) is linked to the generation of multiple-quantum…
A quantitative aspect of the Heisenberg uncertainty
A. K. Khitrin
Minimization of the expectation value of energy under the constraints imposed by the uncertainty principle can be a convenient method of solving quantum-mechanical problems.
Reversible Projective Measurement in Quantum Ensembles
Anatoly Khitrin, Michael Michalski, Jae-Seung Lee
We present experimental NMR demonstration of a scheme of reversible projective measurement, which allows extracting information on outcomes and probabilities of a projective measur…
Experimental Implementation of Projective Measurement in Bell Basis
Jae-Seung Lee, A. K. Khitrin
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…
Controlled spontaneous emission
Jae-Seung Lee, Mary A. Rohrdanz, A. K. Khitrin
The problem of spontaneous emission is studied by a direct computer simulation of the dynamics of a combined system: atom + radiation field. The parameters of the discrete finite m…
Experimental demonstration of stimulated polarization wave in a chain of nuclear spins
Jae-Seung Lee, Travis Adams, A. K. Khitrin
A stimulated wave of polarization, which implements a simple mechanism of quantum amplification, is experimentally demonstrated in a chain of four J-coupled nuclear spins, irradiat…
