Cryogenic Multiplexing Control Chip for Superconducting Quantum Processor
Rutian Huang, Xiao Geng, Xinyu Wu +4
This paper proposes a scheme and design of cryogenic multiplexing control chip (MCC) which enables one microwave cable to control many superconducting qubits. Designed based on adj…
Oval-shaped resonance distortion as a signature of quasiparticle heating effect in a niobium superconducting resonator
Zhenyuan Sun, Genting Dai, Xiao Geng +8
We investigate the nonlinear behavior of a superconducting microwave resonator subjected to a dissipative mechanism where the associated quality factor (Q factor) decreases with in…
Qubit Energy Tuner Based on Single Flux Quantum Circuits
Xiao Geng, Rutian Huang, Yongcheng He +9
A device called qubit energy tuner (QET) based on single flux quantum (SFQ) circuits is proposed for Z control of superconducting qubits. Created from the improvement of flux digit…
Measurement Of Energy Resolution For TES Microcalorimeter With Optical Pulses
Shuo Zhang, Qing-Ya Zhang, CongZhan Liu +3
Energy resolution is an important figure of merit for TES microcalorimeter. We propose a laser system to measure the energy resolution of TES microcalorimeter with a 1550 nm laser…
Method for identifying electromagnetically induced transparency in a tunable circuit quantum electrodynamics system
Qi-Chun Liu, Tie-Fu Li, Xiao-Qing Luo +9
Electromagnetically induced transparency (EIT) has been realized in atomic systems, but fulfilling the EIT conditions for artificial atoms made from superconducting circuits is a m…
Quantum coherence between cavity and artificial atom in a superconducting circuit QED ladder system
Qichun Liu, Han Cai, Yingshan Zhang +2
We have created a quantum three-level ladder system with the cavity dispersive energy level in a superconducting circuit quantum electrodynamics system consisting of a transmon qub…
