Different Circuit Diagrams

Equivalent circuit diagrams for two different implementations of... . Download scientific diagram | Equivalent circuit diagrams for two different implementations of two-resonator circuit QED based on either a charge qubit [(a)-(c)] or a flux qubit [(d)-(f)]. Cf. Subsec. II C for details. (a) b V ra and b V rb : Quantized voltage sources associated with resonators A and B in parallel to the self-capacitances C ra and C rb of the resonators. ˆ I ra andˆIandˆ andˆI rb : Quantized current sources associated with resonators A and B in series to the self-inductances L ra and L rb of the resonators. The number of excess Cooper pairs on the charge qubit island (big dot) is n|ˆnn|ˆ n|ˆn |n. C J : Capacitance of each of the two Josephson tunnel junctions connecting the island to ground. C ga and C gb : Coupling capacitances between the qubit and the two resonators. C ab : First-order cross-capacitance between A and B (typically small, dotted line). The dashed box marks a T-network composed of C ga , 2C J , and C gb. (b) C cr ≡ C ga C gb /C Σ : Second-order cross-capacitance. C sa ≡ 2C J C ga /C Σ and C sb ≡ 2C J C gb /C Σ : Resonator shift capacitances. C ab is neglected for simplicity. (c) The circuits of (b) rearranged as a single Π-network (dashed box). The latter is equivalent to the T-network of (a). The magnitudes of C ra and C rb are increased by the presence of the shift capacitances C sa and C sb. (d) Two resonators A and B inductively coupled via M qa and M qb to a flux qubit with total self-inductance L q = L q /2 + L q /2 and flux operator b Φ. The first-order mutual inductance m between the two resonators is neglected to simplify the notation. (e) The disconnected circuit of (d) is transformed into a connected circuit. 57 Again, we can identify a Π-network (dashed box). (f) Left side: T-network obtained from the Π-network of (e). We identify the second-order mutual inductance M cr ≡ M qa M qb /L q and the shift inductances L sa ≡ M 2 qa /L q and L sb ≡ M 2 qb /L q. Right side: The connected circuit on the left side is transformed into a disconnected circuit. 57 from publication: Two-resonator circuit quantum electrodynamics: A superconducting quantum switch | We introduce a systematic formalism for two-resonator circuit QED, where two on-chip microwave resonators are simultaneously coupled to one superconducting qubit.
