Superconducting Q-bits in a transom regime coupled to a 1-D waveguide

7.9 GHz

Broken inversion symmetry is created by detuning one Q-bit.

Components for more versatile and efficient signal routing and processing in quantum technologies.

Weak anharmonicity reduces diode efficiency below 2/3. 1st order coherent functions approached 0.5 for transmitted and reflected signals in the stationary state, and 2nd order tend to coincide.
