Deterministic Control of Photon-Number Probabilities via Phase-Controlled Quantum Interference
Sang Kyu Kim, Eduardo Zubizarreta Casalengua, Yeji Sim +8
Deterministically tailoring optical Fock states beyond the single-photon level is crucial for boson sampling, loss-tolerant photonic qubits, and quantum-enhanced sensing, however h…
Unlocking multiphoton emission from a single-photon source through mean-field engineering
Sang Kyu Kim, Eduardo Zubizarreta Casalengua, Katarina Boos +9
Single-photon emission from a two-level system offers promising perspectives for the development of quantum technologies, where multiphotons are generally regarded as accidental, u…
Correlations in Circular Quantum Cascades
Miguel Ángel Palomo Marcos, Eduardo Zubizarreta Casalengua, Elena del Valle +1
We introduce a one-way, one-quantum cascade, whereby a single excitation proceeds one-directionwise in a ladder of energy levels. This makes a variation from more famous two-way ca…
Two photons everywhere
Eduardo Zubizarreta Casalengua, Fabrice P. Laussy, Elena del Valle
We discuss two-photon physics, taking for illustration the particular but topical case of resonance fluorescence. We show that the basic concepts of interferences and correlations…
Photon liquefaction in time
Eduardo Zubizarreta Casalengua, Elena del Valle, Fabrice P. Laussy
We provide a mechanism to imprint local temporal correlations in photon streams which have the same character as spatial correlations in liquids. Usual single-photon emitters corre…
Two-photon emission in detuned resonance fluorescence
Eduardo Zubizarreta Casalengua, Elena del Valle, Fabrice P. Laussy
We discuss two-photon correlations from the side peaks that are formed when a two-level system emitter is driven coherently, with a detuning between the driving source and the emit…
