Non-reciprocal few-photon devices based on chiral waveguide-emitter couplings
C. Gonzalez-Ballestero, Esteban Moreno, F. J. Garcia-Vidal +1
We demonstrate the possibility of designing efficient, non reciprocal few-photon devices by exploiting the chiral coupling between two waveguide modes and a single quantum emitter.…
A chiral route to spontaneous entanglement generation
Carlos Gonzalez-Ballestero, Alejandro Gonzalez-Tudela, Francisco J. Garcia-vidal +1
We study the generation of spontaneous entanglement between two qubits chirally coupled to a waveguide. The maximum achievable concurrence is demonstrated to increase by a factor o…
Optimization of photon correlations by frequency filtering
A. Gonzalez-Tudela, E. del Valle, F. P. Laussy
Photon correlations are a cornerstone of Quantum Optics. Recent works [NJP 15 025019, 033036 (2013), PRA 90 052111 (2014)] have shown that by keeping track of the frequency of the…
The colored Hanbury Brown--Twiss effect
Blanca Silva, C. Sánchez Muñoz, D. Ballarini +8
The Hanbury Brown--Twiss effect is one of the celebrated phenomenologies of modern physics that accommodates equally well classical (interferences of waves) and quantum (correlatio…
Reversible dynamics of single quantum emitters near metal-dielectric interfaces
A. Gonzalez-Tudela, P. A. Huidobro, L. Martin-Moreno +2
Here we present a systematic study of the dynamics of a single quantum emitter near a flat metal-dielectric interface. We identify the key elements that determine the onset of reve…
Two-photon spectra of quantum emitters
A. Gonzalez-Tudela, F. P. Laussy, C. Tejedor +2
We apply our recently developed theory of frequency-filtered and time-resolved N-photon correlations to study the two-photon spectra of a variety of systems of increasing complexit…
Theory of the strong coupling between quantum emitters and propagating surface plasmons
A. Gonzalez-Tudela, P. A. Huidobro, L. Martin-Moreno +2
Here we present the theoretical foundation of the strong coupling phenomenon between quantum emitters and propagating surface plasmons observed in two-dimensional metal surfaces. F…
Theory of frequency-filtered and time-resolved N-photon correlations
Elena del Valle, Alejandro Gonzalez-Tudela, Fabrice P. Laussy +2
A theory of correlations between N photons of given frequencies and detected at given time delays is presented. These correlation functions are usually too cumbersome to be compute…
Exploring qubit-qubit entanglement mediated by one-dimensional plasmonic nanowaveguides
A. Gonzalez-Tudela, D. Martin-Cano, E. Moreno +3
We exploit the qubit-qubit coupling induced by plasmon-polariton modes in a one-dimensional nanowaveguide to obtain various two-qubit entanglement situations. Firstly, we observe t…
Entanglement of two qubits mediated by one-dimensional plasmonic waveguides
A. Gonzalez-Tudela, D. Martin-Cano, E. Moreno +3
We investigate qubit-qubit entanglement mediated by plasmons supported by one-dimensional waveguides. We explore both the situation of spontaneous formation of entanglement from an…
Linear and nonlinear coupling of quantum dots in microcavities
F. P. Laussy, E. del Valle, A. Gonzalez-Tudela +3
We discuss the topical and fundamental problem of strong-coupling between a quantum dot an the single mode of a microcavity. We report seminal quantitative descriptions of experime…
Dissipative dynamics of a solid-state qubit coupled to surface plasmons: from non-Markov to Markov regimes
Alejandro Gonzalez-Tudela, Ferney J. Rodriguez, Luis Quiroga +1
We theoretically study the dissipative dynamics of a quantum emitter placed near the planar surface of a metal supporting surface plasmon excitations. The emitter-metal coupling re…
Two-photon lasing by a single quantum dot in a high-Q microcavity
Elena del Valle, Stefano Zippilli, Fabrice P. Laussy +3
We investigate theoretically two-photon processes in a microcavity containing one quantum dot in the strong coupling regime. The cavity mode can be tuned to resonantly drive the tw…
Effect of pure dephasing on the Jaynes-Cummings nonlinearities
A. Gonzalez-Tudela, E. del Valle, E. Cancellieri +3
We study the effect of pure dephasing on the strong-coupling between a quantum dot and the single mode of a microcavity in the nonlinear regime. We show that the photoluminescence…
Anticrossing in the PL spectrum of light-matter coupling under incoherent continuous pumping
A. Gonzalez-Tudela, E. del Valle, C. Tejedor +1
We compare the observed splitting in the PL spectrum of a strongly coupled light-matter system, with the splitting of its dressed modes. In the presence of non-negligible decoheren…
