Realization of a Qubit: energy spectroscopy and coherence
Benedikt Kratochwil, Jonne V. Koski, Andreas J. Landig +9
The energy landscape of a single electron in a triple quantum dot can be tuned such that the energy separation between ground and excited states becomes a flat function of the rele…
Coherent long-distance spin-qubit-transmon coupling
A. J. Landig, J. V. Koski, P. Scarlino +10
Spin qubits and superconducting qubits are among the promising candidates for a solid state quantum computer. For the implementation of a hybrid architecture which can profit from…
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…
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…
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…
