TSC add-on

When the number of sample contacts becomes very large, or when external instruments deliver many signals to be digitized, 8 input and output channels might simply not be enough. One additional TSC instantaneously doubles that number to 16. For even more complex experiments, a maximum of 3 TSCs can be connected to the Nanonis Tramea™ base configuration, transforming the instrument into a 24 outputs and 24 inputs system. Never before has that number of signals been generated or acquired with similar performance.

Nanonis TSC — Nanonis Tramea TSC add-on module

The TSC add-ons are identical to the TSC of the base configuration, meaning no compromise on signal quality. And while increasing the number of channels with conventional systems means adapting the measurement software and potentially changing the workflow, with Nanonis Tramea™ none of this is necessary. The additional TSC signals are seamlessly integrated into the Tramea™ software allowing immediate productivity. For cases where more signal outputs than signal inputs are necessary, the Nanonis TSO add-on might be the better solution.

Additional TSCs can be combined with additional TSO5 (16-output channels) if more outputs than inputs are required.

(2019) Gate Tunable Hole Charge Qubit Formed in a Ge/Si Nanowire Double Quantum Dot Coupled to Microwave Photons

A controllable and coherent light-matter interface is an essential element for a scalable quantum information processor. Strong coupling to an on-chip cavity has been accomplished in various electron quantum dot systems, but rarely explored in the hole systems. Here we demonstrate a hybrid architecture comprising a microwave transmission line resonator controllably coupled to a hole charge qubit formed in a Ge/Si core/shell nanowire (NW), which is a natural one-dimensional hole gas with a strong spin–orbit interaction (SOI) and lack of nuclear spin scattering, potentially enabling fast spin manipulation by electric manners and long coherence times. The charge qubit is established in a double quantum dot defined by local electrical gates. Qubit transition energy can be independently tuned by the electrochemical potential difference and the tunnel coupling between the adjacent dots, opening transverse (σx) and longitudinal (σz) degrees of freedom for qubit operation and interaction. As the qubit energy is swept across the photon level, the coupling with resonator is thus switched on and off, as detected by resonator transmission spectroscopy. The observed resonance dynamics is replicated by a complete quantum numerical simulation considering an efficient charge dipole-photon coupling with a strength up to 2π × 55 MHz, yielding an estimation of the spin-resonator coupling rate through SOI to be about 10 MHz. The results inspire the future researches on the coherent hole-photon interaction in Ge/Si nanowires.
