Microwave-multiplexed qubit controller using adiabatic superconductor logic
Naoki Takeuchi, Taiki Yamae, Taro Yamashita +2
Cryogenic qubit controllers (QCs) are the key to build large-scale superconducting quantum processors. However, developing scalable QCs is challenging because the cooling power of…
Low-latency adiabatic quantum-flux-parametron circuit integrated with a hybrid serializer/deserializer
Yuki Hironaka, Taiki Yamae, Christopher L. Ayala +2
Adiabatic quantum-flux-parametron (AQFP) logic is an ultra-low-power superconductor logic family. AQFP logic gates are powered and clocked by dedicated clocking schemes using ac ex…
Adiabatic quantum-flux-parametron with delay-line clocking: logic gate demonstration and phase skipping operation
Taiki Yamae, Naoki Takeuchi, Nobuyuki Yoshikawa
Adiabatic quantum-flux-parametron (AQFP) logic is an energy-efficient superconductor logic family. The latency of AQFP circuits is relatively long compared to that of other superco…
An adiabatic superconductor comparator with 46 nA sensitivity
Naoki Takeuchi, Taiki Yamae, Hideo Suzuki +1
Adiabatic quantum-flux-parametron (AQFP) circuits can operate with extremely small energy dissipation (~1 zJ per junction at 5 GHz) and high sensitivity (~1 μA) owing to adiabatic…
Impedance Design of Excitation Lines in Adiabatic Quantum-Flux-Parametron Logic Using InductEx
Naoki Takeuchi, Hideo Suzuki, Coenrad J. Fourie +1
The adiabatic quantum-flux-parametron (AQFP) is an energy-efficient superconductor logic family that utilizes adiabatic switching. AQFP gates are powered and clocked by ac excitati…
Scalable readout interface for superconducting nanowire single-photon detectors using AQFP and RSFQ logic families
Naoki Takeuchi, Fumihiro China, Shigehito Miki +4
We propose a scalable readout interface for superconducting nanowire single-photon detector (SSPD) arrays, which we call the AQFP/RSFQ interface. This interface is composed of adia…
