Strategies for enabling quantum development with testing and measurement from 77K to millikelvins
Quantum computing will likely utilize numerous new technologies that operate at multiple different cryogenic temperatures. For example, a quantum computer can deploy 77K CMOS memory modules, 4K superconducting control chips, and a quantum processing unit (QPU) of less than 20 mK.
This was already emphasized in 2020 in an interview with Fabio Sebastiano. A strategy with testing and measuring is mentioned during his lecture by Dong-Tuc from Microtron.
Double-Superheterodyne architecture for high-fidelity quantum computer control and readout
Controlling and reading a quantum computer requires generating and acquiring a multitude of microwave signals. The quality of this has a direct influence on the performance of the quantum computer in terms of controllability and the quality of the readout.
This requires a signal source with low noise and phase noise, a large bandwidth and low transit time as well as excellent long-term stability. A typical solution uses carefully calibrated IQ mixers but has the disadvantage of relatively low bandwidth and poor long-term stability. In addition, continuous recalibration must take place in order to function optimally.
Sign up for Lab tours at QuTech
The program of the RF Technology event is full of high-tech knowledge about quantum computing, qubits, quantum hardware and high-frequency technology. The expertise and expertise can certainly be experienced online, but you really want to experience a physical tour of the various laboratories at QuTech.
This is a privilege of the visitors to the RF Technology event. You can go to the Steele lab, the microwave group lab, the QuTech institute lab and the spin-offs QBlox and Delft Circuits.
