A tunable chiral light-matter interface with on-chip spin control
Shikai Liu, Joan Alba, Bálint Sárközi +5
The ability to engineer chiral light-matter interactions is a valuable resource for realizing quantum networks and non-reciprocal quantum optics. Here, we demonstrate chiral coupli…

Quantifying entanglement in quantum thermodynamics via separability constraints
Joan Alba, Laura Ares, Jan Sperling +1
The role of quantum entanglement in thermodynamical systems remains elusive. Does entanglement result in thermodynamic advantages or does it impose fundamental limitations? Here, w…

Steady-State Multiparticle Entanglement via Dissipative Engineering in Waveguide QED
Joan Alba, Jacob Thornfeldt Hansen, Jean-Baptiste S. Béguin +1
We propose a simple scheme for the dissipative generation of entangled states of multiple emitters coupled to a waveguide. Our approach exploits collective interactions arising fro…
