Deterministic generation of grid states with programmable nonlinear bosonic circuits
Yanis Le Fur, Javier Lalueza-Puértolas, Carlos Sánchez Muñoz +2
Bosonic quantum error correction enables hardware-efficient protection of quantum information by encoding logical qubits in harmonic oscillators. Bosonic grid states, such as Gotte…
Entanglement of two optical emitters mediated by a terahertz channel
Yanis Le Fur, Diego MartÃn-Cano, Carlos Sánchez Muñoz
Quantum technologies in the terahertz (THz) require a coherent interface between addressable qubits and THz quantum channels -- a capacity that so far, remains largely underdevelop…
Quantum metrology through spectral measurements in quantum optics
Alejandro Vivas-Viaña, Carlos Sánchez Muñoz
Continuously monitored quantum systems are emerging as promising platforms for quantum metrology, where a central challenge is to identify measurement strategies that optimally ext…
Deterministic single-photon source over the terahertz regime
Caspar Groiseau, Miguel Ã. MartÃnez-GarcÃa, Diego MartÃn-Cano +1
The terahertz (THz) regime still lacks a source capable of emitting single photons deterministically. Here, we propose an on-demand THz single-photon source, triggered by a sequenc…
Quantum amplification and simulation of strong and ultrastrong coupling of light and matter
Wei Qin, Anton Frisk Kockum, Carlos Sánchez Muñoz +2
The interaction of light and matter at the single-photon level is of central importance in various fields of physics, including, e.g., condensed matter physics, astronomy, quantum…
