“…This effect gets stronger as the coupling to the line increases, thus rendering the decay into the line as the dominant decay channel of the qubit. This type of one-dimensional fluorescence effect has been observed experimentally [10] and it could have applications for single-photon switches [11], routers [12], photon detectors [13], and interferometers with single-atom mirrors [14].…”

Strong coupling between surface plasmon polaritons and emitters: a review

Abstract. In this review we look at the concepts and state-of-the-art concerning the strong coupling of surface plasmon-polariton modes to states associated with quantum emitters such as excitons in J-aggregates, dye molecules and quantum dots. We explore the phenomenon of strong coupling with reference to a number of examples involving electromagnetic fields and matter. We then provide a concise description of the relevant background physics of surface plasmon polaritons. An extensive overview of the historical background and a detailed discussion of more recent relevant experimental advances concerning strong coupling between surface plasmon polaritons and quantum emitters is then presented. Three conceptual frameworks are then discussed and compared in depth: classical, semi-classical and fully quantum mechanical; these theoretical frameworks will have relevance to strong coupling beyond that involving surface plasmon polaritons. We conclude our review with a perspective on the future of this rapidly emerging field, one we are sure will grow to encompass more intriguing physics and will develop in scope to be of relevance to other areas of science.

“…This would be important both from a fundamental point of view, since coherent dynamics in multilevel atoms clearly displays beautiful interference phenomena 4 , and for applications. These include the implementation of microwave quantum switches 10 , the manipulation of solid-state qubit circuits 11 and the fascinating perspectives of coupling strongly such nanodevices to electromagnetic 12,13 or nanomechanical quantized modes 9 . Very recently few experiments have demonstrated features of multilevel coherence in such devices, as the Autler-Townes (AT) splitting 14,15 , EIT 16 , preparation and measurement of threestate superpositions 17 , dynamical AT control 10 and coherent population trapping 18 .…”

Design of a Lambda system for population transfer in superconducting nanocircuits

et al. 2013

The implementation of a Lambda scheme in superconducting artificial atoms could allow detection of stimulated Raman adiabatic passage (STIRAP) and other quantum manipulations in the microwave regime. However symmetries which on one hand protect the system against decoherence, yield selection rules which may cancel coupling to the pump external drive. The tradeoff between efficient coupling and decoherence due to broad-band colored Noise (BBCN), which is often the main source of decoherence is addressed, in the class of nanodevices based on the Cooper pair box (CPB) design. We study transfer efficiency by STIRAP, showing that substantial efficiency is achieved for off-symmetric bias only in the charge-phase regime. We find a number of results uniquely due to non-Markovianity of BBCN, namely: (a) the efficiency for STIRAP depends essentially on noise channels in the trapped subspace; (b) low-frequency fluctuations can be analyzed and represented as fictitious correlated fluctuations of the detunings of the external drives; (c) a simple figure of merit for design and operating prescriptions allowing the observation of STIRAP is proposed. The emerging physical picture also applies to other classes of coherent nanodevices subject to BBCN.

“…Resonant driving Detuned driving Resonant driving Although our study focuses on a three-level superconducting flux qubit circuit, the method used here can be easily applied to a superconducting phase [45][46][47] and Xmon [50] qubit circuits or other quantum circuits in which the inversion symmetry of their potential energy is broken. In contrast to large anharmonicity of the flux qubit circuits, the superconducting phase and Xmon qubit circuits have small anharmonicity.…”

Realization of microwave amplification, attenuation, and frequency conversion using a single three-level superconducting quantum circuit

et al. 2017

View full text Add to dashboard Cite

Using different configurations of applied strong driving and weak probe fields, we find that only a single three-level superconducting quantum circuit (SQC) is enough to realize amplification, attenuation and frequency conversion of microwave fields. Such a three-level SQC has to possess ∆-type cyclic transitions. Different from the parametric amplification (attenuation) and frequency conversion in nonlinear optical media, the real energy levels of the three-level SQC are involved in the energy exchange when these processes are completed. We quantitatively discuss the effects of amplification (attenuation) and the frequency conversion for different types of driving fields. The optimal points are obtained for achieving the maximum amplification (attenuation) and conversion efficiency. Our study provides a new method to amplify (attenuate) microwave, realize frequency conversion, and also lay a foundation for generating single or entangled microwave photon states using a single three-level SQC.
