Abstract
Electrical communication between a sample (such as a quantum chip, semiconductor sample etc.) in a low temperature environment and an external device is affected via signal lines printed on rigid printed circuit board (PCB) located within a region of the low temperature environment (e.g., a non-uniform magnetic field region). One example application is performing a measurement of an electrical property of the sample at a low signal frequency with a short measurement integration time, although the subject matter is not limited in this respect. Another application is routing an electrical control signal to the sample.
Claims20
A system comprising:
- a dilution refrigerator configured to refrigerate an enclosure;
- a magnetic system configured to apply a magnetic field across a magnetic field region within the enclosure;
