In this article, a cryogenically cooled SiGe BiCMOS integrated circuit is described and used to achieve >98% readout fidelity when measuring the state of a superconducting transmon qubit coupled to a 6.5-GHz resonant cavity. The circuit employs homodyne detection and uses a novel local oscillator chopping approach to reduce the effects of LO-RF feedthrough in the presence of a high-gain LNA. At 6 mW, the integrated circuit is employed to demonstrate comparable fidelity to a standard HEMT-amplifier-based readout setup, when preceded by a Josephson parametric amplifier with $geq sim 18$ dB of power gain. In addition, this performance is achieved with the IC consuming less power than the commercial HEMT LNA used in the standard readout setup. To the best of the authors’ knowledge, this is the first demonstration of high-fidelity state readout of superconducting qubits without a standalone cryogenic semiconductor LNA. This demonstration represents an important step in the realization of fully integrated large-scale cryogenic qubit control systems.

This article presents a real-time identification process for slow motion-modulated chipless radio frequency identification (RFID), which can be applied to human hand gestures to realize a full-practical long-range RFID system with gesture recognition capability. Depolarizing chipless tags configured by hand in three gestures are utilized, while different motion-induced modulation effects involved in each gesture are analytically modeled. The identification based on differential radar cross-section (RCS) and gesture recognition using deterministic in-phase/quadrature (IQ) trajectories is addressed according to the developed model. The fast reading process for slow motion-modulated chipless RFID is proposed based on the sequential fast frequency sweep acquisitions by vector network analyzer (VNA), while the sweep time is very short compared to the period of motion. The identification time achieved using this approach is about only a few periods of motion, which is ideal for implementing hand gesture-modulated chipless RFID in real time. The designed gesture-modulated chipless tag is identified during a few seconds at distances up to 3 m for the most efficient gesture. Moreover, all the hand gestures are recognized at the 2-m range based on the received IQ signature. These achievements realize the practical example of motion-modulated chipless RFID where both tag identification and gesture recognition are simultaneously provided.
