• Abstract summary: Quantum processing units will be modules of larger information processing systems containing also digital and analog electronics modules. Here, we present a cryogenic multi- module assembly for multiplexed readout of silicon quantum devices. We show each module individually and show (i) a gain over 35 dB, a bandwidth of 118 MHz, a minimum noise temperature of 4.2 K, (ii) an insertion loss smaller than 1.1 dB, a noise temperature smaller than 1.1K across 0-2 GHz, and (iii) single-electron box (SEB) charge sensors.

• Abstract: Quantum processing units will be modules of larger information processing systems containing also digital and analog electronics modules. Silicon-based quantum computing offers the enticing opportunity to manufacture all the modules using the same technology platform. Here, we present a cryogenic multi-module assembly for multiplexed readout of silicon quantum devices where all modules have been fabricated using the same fully-depleted silicon-on-insulator (FDSOI) CMOS process. The assembly is constituted by three chiplets: (i) a low-noise amplifier (LNA), (ii) a single-pole eight-throw switch (SP8T), and (iii) a silicon quantum dot (QD) array. We characterise each module individually and show (i) a gain over 35 dB, a bandwidth of 118 MHz, a minimum noise temperature of 4.2 K, (ii) an insertion loss smaller than 1.1 dB, a noise temperature smaller than 1.1~K across 0-2 GHz, and (iii) single-electron box (SEB) charge sensors. Finally, we combine all elements into a single demonstration showing time-domain radio-frequency multiplexing of two SEBs paving the way to an all-silicon quantum computing system.

  We present a microwave quantum state router, centered on Josephson-junction based three-wave mixing, that realizes all-to-all couplings among four detachable quantum modules. We demonstrate coherent exchange among all four communication modes, with an average full-iSWAP time of 764ns and average inferred inter-module exchange fidelity of 0.969, limited by mode coherence. Our router-module architecture serves as a prototype of modular quantum computer that has great potential for enabling flexible, demountable, large-scale quantum networks of superconducting qubits and cavities.
