't Hart, P.A. (author)Device characteristics at cryogenic temperatures can deviate significantly from their room temperature behaviour. For example, the threshold voltage of a MOSFET can increase by more than 100 mV when it is cooled down to 4.2 K, as shown in this thesis. If a designer is not aware of this shift, circuits that work as intended at room temperature...doctoral thesis 2022

Cerviño Fungueiriño, David Cervino (author)Quantum computers exploit the quantum behavior of quantum bits (qubits) that are typically operated at cryogenic temperature. Qubits require an electronic control interface. Nowadays, such classical electronic controllers use bulky instruments operated far fromthe qubits outside the cryostat. To run practical quantum algorithms, thousands to...master thesis 2022
