Enabling Deterministic Passive Quantum State Transfer with Giant Atoms
Oliver Diekmann, Enrico Di Benedetto, Nicolas Jungwirth +7
Achieving quantum state transfer in passive ways can become a powerful asset for scalable quantum networks. Here, we demonstrate how giant atoms coupled to 1D waveguides provide a…
Emergent cavity-QED dynamics along the edge of a photonic lattice
Enrico Di Benedetto, Xuejian Sun, Marcel A. Pinto +6
We investigate qubits coupled to the boundary of a two dimensional photonic lattice that supports dispersionless edge modes, unlike conventional edge modes that sustain propagating…
Giant-atom-enabled quantum optics with valley-polarized photons
Marcel A. Pinto, Giovanni Luca Sferrazza, Silvia Casulleras +3
Valleytronics and valley photonics exploit the valley degree of freedom to encode and manipulate information. Here we show that photonic valleys can be selectively addressed in qua…
Superstrong Dynamics and Directional Emission of a Giant Atom in a Structured Bath
Vincent Jouanny, Léo Peyruchat, Marco Scigliuzzo +8
Quantum emitters coupled to waveguides with nonlinear dispersion show rich quantum dynamics with the promise of implementing non-trivial non-Markovian quantum models. Recent advanc…
Dipole-dipole interactions mediated by a photonic flat band
Enrico Di Benedetto, Alejandro Gonzalez-Tudela, Francesco Ciccarello
Flat bands (FBs) are energy bands with zero group velocity, which in electronic systems were shown to favor strongly correlated phenomena. Indeed, a FB can be spanned with a basis…
Non-Markovian dynamics of a qubit due to accelerated light in a lattice
Marcel Augusto Pinto, Giovanni Luca Sferrazza, Daniele De Bernardis +1
We investigate the emission of a qubit weakly coupled to a one-band coupled-cavity array where, due to an engineered gradient in the cavity frequencies, photons are effectively acc…
