Steady-State Entanglement in the Nuclear Spin Dynamics of a Double Quantum Dot
Martin J. A. Schuetz, Eric M. Kessler, Lieven M. K. Vandersypen +2
We propose a scheme for the deterministic generation of steady-state entanglement between the two nuclear spin ensembles in an electrically defined double quantum dot. Due to quant…
Photon- and phonon-assisted tunneling in the three-dimensional charge stability diagram of a triple quantum dot array
Floris R. Braakman, Pierre Barthelemy, Christian Reichl +2
We report both photon- and phonon-assisted tunneling transitions in a linear array of three quantum dots, which can only be understood by considering the full three-dimensionality…
Simultaneous Spin-Charge Relaxation in Double Quantum Dots
V. Srinivasa, K. C. Nowack, M. Shafiei +2
We investigate phonon-induced spin and charge relaxation mediated by spin-orbit and hyperfine interactions for a single electron confined within a double quantum dot. A simple toy…
Long-range coherent coupling in a quantum dot array
Floris R. Braakman, Pierre Barthelemy, Christian Reichl +2
Controlling long-range quantum correlations is central to quantum computation and simulation. In quantum dot arrays, experiments so far rely on nearest-neighbour couplings only, an…
Excitation of a Si/SiGe quantum dot using an on-chip microwave antenna
E. Kawakami, P. Scarlino, L. R. Schreiber +5
We report transport measurements on a Si/SiGe quantum dot subject to microwave excitation via an on-chip antenna. The response shows signatures of photon-assisted tunneling and onl…
