Microwave cavity detected spin blockade in a few electron double quantum dot
A. J. Landig, J. V. Koski, P. Scarlino +5
We investigate spin states of few electrons in a double quantum dot by coupling them weakly to a magnetic field resilient NbTiN microwave resonator. We observe a reduced resonator…
Direct observation of energy spectrum transition in narrow AlAs quantum wells
A. R. Khisameeva, A. V. Shchepetilnikov, V. M. Muravev +8
Spectra of magnetoplasma excitations have been investigated in a two-dimensional electron systems in AlAs quantum wells (QWs) of different widths. The magnetoplasma spectrum have b…
Universal nuclear focusing of confined electron spins
Sergej Markmann, Christian Reichl, Werner Wegscheider +1
For spin-based quantum computation in semiconductors, dephasing of electron spins by a fluctuating background of nuclear spins is a main obstacle. Here we show that this nuclear ba…
Coherent microwave photon mediated coupling between a semiconductor and a superconductor qubit
P. Scarlino, D. J. van Woerkom, U. C. Mendes +10
Semiconductor qubits rely on the control of charge and spin degrees of freedom of electrons or holes confined in quantum dots (QDs). They constitute a promising approach to quantum…
Microwave photon-mediated interactions between semiconductor qubits
David J. van Woerkom, Pasquale Scarlino, Jann H. Ungerer +8
The realization of a coherent interface between distant charge or spin qubits in semiconductor quantum dots is an open challenge for quantum information processing. Here we demonst…
Automated tuning of inter-dot tunnel couplings in quantum dot arrays
C. J. van Diepen, P. T. Eendebak, B. T. Buijtendorp +5
Semiconductor quantum dot arrays defined electrostatically in a 2D electron gas provide a scalable platform for quantum information processing and quantum simulations. For the oper…
Floquet spectroscopy of a strongly driven quantum dot charge qubit with a microwave resonator
J. V. Koski, A. J. Landig, A. Pályi +7
We experimentally investigate a strongly driven GaAs double quantum dot charge qubit weakly coupled to a superconducting microwave resonator. The Floquet states emerging from stron…
A 2x2 quantum dot array with controllable inter-dot tunnel couplings
Uditendu Mukhopadhyay, Juan Pablo Dehollain, Christian Reichl +2
The interaction between electrons in arrays of electrostatically defined quantum dots is naturally described by a Fermi-Hubbard Hamiltonian. Moreover, the high degree of tunability…
