Epitaxy of strained, nuclear-spin free Ge quantum wells from solid source materials
Maximilian Oezkent, Chen-Hsun Lu, Lucas Becker +13
Germanium quantum well heterostructures have rapidly emerged as a leading platform for solid-state quantum information processing; however, material quality limits scalability, and…
Periodic Field Emission from an Isolated Nano-Scale Electron Island
D. V. Scheible, C. Weiss, J. P. Kotthaus +1
We observe field emission from an isolated nano-machined gold island. The island is able to mechanically oscillate between two facing electrodes, which provide recharging and detec…
Spin blockade in ground state resonance of a quantum dot
A. K. Huettel, H. Qin, A. W. Holleitner +5
We present measurements on spin blockade in a laterally integrated quantum dot. The dot is tuned into the regime of strong Coulomb blockade, confining ~ 50 electrons. At certain el…
Adiabatic steering and determination of dephasing rates in double dot qubits
T. Brandes, F. Renzoni, R. H. Blick
We propose a scheme to prepare arbitrary superpositions of quantum states in double quantum--dots irradiated by coherent microwave pulses. Solving the equations of motion for the d…
A nanomechanical resonator shuttling single electrons at radio frequencies
A. Erbe, C. Weiss, W. Zwerger +1
We observe transport of electrons through a metallic island on the tip of a nanomechanical pendulum. The resulting tunneling current shows distinct features corresponding to the di…
Coherent coupling of two quantum dots embedded in an Aharonov-Bohm ring
A. W. Holleitner, C. R. Decker, K. Eberl +1
We define two laterally gated small quantum dots (~ 15 electrons) in an Aharonov-Bohm geometry in which the coupling between the two dots can be broadly changed. For weakly coupled…
