Edoardo Charbon, Fabio Sebastiano
The design of a large-scale quantum computer requires co-optimization of both the quantum bits (qubits) and their control electronics. This work presents the first systematic design of such a controller to simultaneously and accurately manipulate the state ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2020A 10-to-12 GHz 5mW Charge-Sampling PLL Achieving 50 fsec RMS Jitter,-258.9 dB FOM and-65 dBc Reference Spur
Edoardo Charbon, Fabio Sebastiano
This paper presents a charge-sampling PLL (CSPLL), that demonstrates the best reported jitter-power FOM of -258.9 dB thanks to its high phase-detection gain and to the removal of the power-hungry buffer driving the phase detector. It also achieves -65 dBc ...
IEEE2020Cryo-CMOS for Analog/Mixed-Signal Circuits and Systems
Edoardo Charbon, Fabio Sebastiano
CMOS circuits operating at cryogenic temperature (cryo-CMOS) are required in several low-temperature applications. A compelling example is the electronic interface for quantum processors, which must reside very close to the cryogenic quantum devices it ser ...
IEEE2020The electronic interface for quantum processors
Edoardo Charbon, Fabio Sebastiano
Quantum computers can potentially provide an unprecedented speed-up with respect to traditional computers. However, a significant increase in the number of quantum bits (qubits) and their performance is required to demonstrate such quantum supremacy. While ...
