A sparse spin qubit array with integrated control electronics
Jelmer M. Boter, Juan P. Dehollain, Jeroen P. G. van Dijk +6
Current implementations of quantum computers suffer from large numbers of control lines per qubit, becoming unmanageable with system scale up. Here, we discuss a sparse spin-qubit…
Characterization and Analysis of On-Chip Microwave Passive Components at Cryogenic Temperatures
Bishnu Patra, Mohammadreza Mehrpoo, Andrea Ruffino +3
This paper presents the characterization of microwave passive components, including metal-oxide-metal (MoM) capacitors, transformers, and resonators, at deep cryogenic temperature…
Multiplexed quantum transport using commercial off-the-shelf CMOS at sub-kelvin temperatures
B. Paquelet Wuetz, P. L. Bavdaz, L. A. Yeoh +10
Continuing advancements in quantum information processing have caused a paradigm shift from research mainly focused on testing the reality of quantum mechanics to engineering qubit…
The electronic interface for quantum processors
Jeroen P. G. van Dijk, Edoardo Charbon, Fabio Sebastiano
Quantum computers can potentially provide an unprecedented speed-up with respect to traditional computers. However, a significant increase in the number of quantum bits (qubits) an…
The impact of classical control electronics on qubit fidelity
Jeroen P. G. van Dijk, Erika Kawakami, Raymond N. Schouten +5
Quantum processors rely on classical electronic controllers to manipulate and read out the quantum state. As the performance of the quantum processor improves, non-idealities in th…
