QDevil Quantum Research
Globetek represents QDevil who are in the Quantum Electronics business – they focus on developing and manufacturing auxiliary electronics and specialized components, operating from milli-Kelvin to room temperature.
QCage is a sample holder system for microwave resonator-based quantum devices such as superconducting quantum processors.
QDAC-II is a high-precision ultra-low-noise computer controlled DAC with 24 voltage generators, operating at a sample rate of 1MS/s – a thousand times faster than its predecessor. It is designed for DC and intermediate-frequency control of quantum devices, including, for example, gate electrodes and flux bias coils in qubits, but is a very versatile instrument that can be used for many other purposes.
The QBox is a fully shielded breakout box specialized for electronics labs and low-temperature experiments. The QBox extends the Faraday cage of the cryostat going from a 24 pin Fischer connector to a convenient 24 channel BNC connector panel. All wiring inside the QBox is done in twisted pairs for best noise immunity.
The QFilter is a compact multi-stage low-pass filter which rejects noise and to ensure millikelvin electron temperature in up to 48 signal lines going to your quantum electronics devices and other sensitive cryogenic and low-temperature electronic circuits. It is the result of several years of development at Harvard University and the University of Copenhagen on achieving the lowest possible noise and electron temperature in quantum circuits. The standard QFilter contains two low-pass filter banks, one with RC circuits and one with LC circuits, but other combinations can also be supplied.
QBoard is a modular, PCB-based cryogenic sample holder system for low-temperature electronic devices, such as spin-qubit chips and superconducting circuits. It has 48 DC/low-frequency channels and 16 high-frequency channels (GHz) and offers excellent thermalization down to millikelvin.
