Dynamics of Coupled Qubits Interacting with an Off-Resonant Cavity
Oliver Gywat, Florian Meier, Daniel Loss +1
We study a model for a pair of qubits which interact with a single off-resonant cavity mode and, in addition, exhibit a direct inter-qubit coupling. Possible realizations for such…
Faraday Rotation Spectroscopy of Quantum-Dot Quantum Wells
Florian Meier, David D. Awschalom
Time-resolved Faraday rotation studies of CdS/CdSe/CdS quantum-dot quantum wells have recently shown that the Faraday rotation angle exhibits several well-defined resonances as a f…
Spin dynamics and level structure of quantum-dot quantum wells
Jesse Berezovsky, Min Ouyang, Florian Meier +3
We have characterized CdS/CdSe/CdS quantum-dot quantum wells using time-resolved Faraday rotation (TRFR). The spin dynamics show that the electron g-factor varies as a function of…
Reduced Visibility of Rabi Oscillations in Superconducting Qubits
Florian Meier, Daniel Loss
Coherent Rabi oscillations between quantum states of superconducting micro-circuits have been observed in a number of experiments, albeit with a visibility which is typically much…
Spin-Photon Dynamics of Quantum Dots in Two-mode Cavities
Florian Meier, David D. Awschalom
A quantum dot interacting with two resonant cavity modes is described by a two-mode Jaynes-Cummings model. Depending on the quantum dot energy level scheme, the interaction of a si…
Molecular spintronics: Coherent spin transfer in coupled quantum dots
Florian Meier, Veronica Cerletti, Oliver Gywat +2
Time-resolved Faraday rotation has recently demonstrated coherent transfer of electron spin between quantum dots coupled by conjugated molecules. Using a transfer Hamiltonian ansat…
Quantum computing with antiferromagnetic spin clusters
Florian Meier, Jeremy Levy, Daniel Loss
We show that a wide range of spin clusters with antiferromagnetic intracluster exchange interaction allows one to define a qubit. For these spin cluster qubits, initialization, qua…
Magnetization transport and quantized spin conductance
Florian Meier, Daniel Loss
We analyze transport of magnetization in insulating systems described by a spin Hamiltonian. The magnetization current through a quasi one-dimensional magnetic wire of finite lengt…
Quantum computing with spin cluster qubits
Florian Meier, Jeremy Levy, Daniel Loss
We study the low energy states of finite spin chains with isotropic (Heisenberg) and anisotropic (XY and Ising-like) exchange interaction with uniform and non-uniform coupling cons…
Quantum Spin Dynamics in Molecular Magnets
Michael N. Leuenberger, Florian Meier, Daniel Loss
The detailed theoretical understanding of quantum spin dynamics in various molecular magnets is an important step on the roadway to technological applications of these systems. Qua…
Spin dynamics and coherent tunnelling in the molecular magnetic rings Fe_6 and Fe_8
A. Honecker, F. Meier, Daniel Loss +1
We present detailed calculations of low-energy spin dynamics in the ``ferric wheel'' systems Na:Fe_6 and Cs:Fe_8 in a magnetic field. We compute by exact diagonalisation the low-en…
Thermodynamics and Spin Tunneling Dynamics in Ferric Wheels with Excess Spin
Florian Meier, Daniel Loss
We study theoretically the thermodynamic properties and spin dynamics of a class of magnetic rings closely related to ferric wheels, antiferromagnetic ring systems, in which one of…
Electron and Nuclear Spin Dynamics in Antiferromagnetic Molecular Rings
Florian Meier, Daniel Loss
We study theoretically the spin dynamics of the ferric wheel, an antiferromagnetic molecular ring. For a single nuclear or impurity spin coupled to one of the electron spins of the…
