“…As in the previous case, the eigenvector |λ 2 is equal to that of the bright state of a three-level system [39,40], if we replace the lower states by the superposition states |ψ 1 and |ψ 2 . The time behavior of eigenvalues λ i in the special case above for different pulse sequences is demonstrated in Figs.…”

Pulse propagation, population transfer, and light storage in five-level media

et al. 2015

We consider adiabatic interaction of five-level atomic systems and their media with four short laser pulses under the condition of all two-photon detunings being zero. We derive analytical expressions for eigenvalues of the system's Hamiltonian and determine conditions of adiabaticity for both the atom and the medium. We analyze, in detail, the system's behavior when the eigenvalue with nonvanishing energy is realized. As distinct from the usual dark state of a five-level system (corresponding to zero eigenvalue), which is a superposition of three states, in our case the superposition of four states does work. We demonstrate that this seemingly unfavorable case nevertheless completely imitates a three-level system not only for a single atom but also in the medium, since the propagation equations are also split into those for three-and two-level media separately. We show that, under certain conditions, all the coherent effects observed in three-level media, such as population transfer, light slowing, light storage, and so on, may efficiently be realized in five-level media. This has an important advantage that the light storage can be performed twice in the same medium; i.e., the second pulse can be stored without retrieving the first one, and then the two pulses can be retrieved in any desired sequence.

“…Similarly, the state |λ 2 is analogous to the bright state of a system and we can use these states for adiabatic transfer from state |5 to state |1 by a b-STIRAP-like process [39,40] driven by the pulse sequence in Fig. 3, because the state |λ 2 is not realized with the pulse sequence of Fig.…”

AbstractAn optical Toffoli gate is the essential logical element, which permits the implementation of a reversible optical processor. We propose a simple realization of such a gate in films of crystals doped with rare-earth ions. The proposed scheme is based on adiabatic population transfer in a Λ-system by means of counterintuitive and intuitive sequences of short laser pulses. We also discuss possibilities for experimental realization of the proposed gate.

“…STIRAP can coherently transfer population by adiabatically changing a dark state [11][12][13] . The same process is also possible through a bright state (b-STIRAP) 14,15 and both methods have been realized in doped solids 14,[16][17][18] , cold atoms 19 , and quantum dots 20 , to name a few. It has been implemented for coherent manipulation of states 19 in logic operations 21,22 , quantumness witness detection 23 and entanglement generation 24 .…”

Stimulated Raman adiabatic control of a nuclear spin in diamond

et al. 2017

View full text Add to dashboard Cite

Coherent manipulation of nuclear spins is a highly desirable tool for both quantum metrology and quantum computation. However, most of the current techniques to control nuclear spins lack of being fast impairing their robustness against decoherence. Here, based on Stimulated Raman Adiabatic Passage, and its modification including shortcuts to adiabaticity, we present a fast protocol for the coherent manipulation of nuclear spins. Moreover, we show how to initialise a nuclear spin starting from a thermal state, and how to implement Raman control for performing Ramsey spectroscopy to measure the dynamical and geometric phases acquired by nuclear spins.
