Quantum Manipulation Using Light-Atom Interaction
A two-level quantum system in vacuum—in the absence of any perturbing fields—constitutes an ideal clock whose oscillation frequency ω = E/h is given by the energy difference E between the two levels |1〉, |2〉. In a single measurement of duration T performed on a single particle this frequency can be determined with an uncertainty Δω = 1/T. If the measurement is performed simultaneously on N inde...
متن کاملSuperlattice of Single Atom Magnets on Graphene.
Regular arrays of single atoms with stable magnetization represent the ultimate limit of ultrahigh density storage media. Here we report a self-assembled superlattice of individual and noninteracting Dy atoms on graphene grown on Ir(111), with magnetic hysteresis up to 5.6 T and spin lifetime of 1000 s at 2.5 K. The observed magnetic stability is a consequence of the intrinsic low electron and ...
متن کاملQuantum State Reconstruction Using Atom Optics
The development of methods for completely determining the quantum state of an atom or cavity field @1# continues to be an important issue in atomic physics. For example, in the field of quantum optics, schemes have been recently proposed, based on the Stem-Gerlach effect, for completely determining the quantum state of an atom as a way of fully characterizing the quantized electromagnetic field...
متن کاملGround State Hyperfine Structure of Muonic Helium Atom
The muonic helium atom (μe2He) represents the simple three-body atomic system. The interaction between magnetic moments of the muon and electron leads to the hyperfine structure (HFS) of the energy levels. The investigation of the energy spectrum of this atom is important for the check of quantum electrodynamics for three-particle bound state. The ground state hyperfine splitting was measured m...
متن کاملQuantum-Dot Spin Qubit and Hyperfine Interaction
We review our investigation of the spin dynamics for two electrons confined to a double quantum dot under the influence of the hyperfine interaction between the electron spins and the surrounding nuclei. Further we propose a scheme to narrow the distribution of difference in polarization between the two dots in order to suppress hyperfine induced decoherence.
