Proposal for Superconducting Quantum Networks Using Multi-Octave Transduction to Lower Frequencies
Takuma Makihara, Wentao Jiang, Amir H. Safavi-Naeini
We propose networking superconducting quantum circuits by transducing their excitations (typically 4-8 GHz) to 100-500 MHz photons for transmission via cryogenic coaxial cables. Co…

A parametrically programmable delay line for microwave photons
Takuma Makihara, Nathan Lee, Yudan Guo +2
Delay lines that store quantum information are crucial for advancing quantum repeaters and hardware efficient quantum computers. Traditionally, they are realized as extended system…
