Heralding probability optimization for nonclassical light generated by photon counting measurements on multimode Gaussian states
JaromÃr Fiurášek, Jaromír Fiurášek
Generation of highly non-classical quantum states of light is essential for optical quantum information processing and quantum metrology. Given the lack of sufficiently strong nonl…
Simplified scheme for continuous-variable entanglement distillation: multicopy distillation of Gaussian entanglement without heralding Gaussian measurements
JaromÃr Fiurášek
Entanglement of continuous-variable Gaussian states can be distilled by combination of de-Gaussifying operation such as single-photon subtraction and iterative heralded Gaussificat…
Extended analysis of distillation and purification of squeezed states of light
JaromÃr Fiurášek, Stephan Grebien, Roman Schnabel
Squeezed states of light are one of the most important fundamental resources for quantum optics, optical quantum information processing and quantum sensing. Recently, it has been e…
Efficient construction of witnesses of stellar rank of nonclassical states of light
JaromÃr Fiurášek
The stellar hierarchy of quantum states of light classifies the states according to the Fock-state resources that are required for their generation together with unitary Gaussian o…
Experimental noiseless quantum amplification of coherent states of light by two-photon addition and subtraction
Michal Neset, JiÅà Fadrný, Martin Bielak +3
Noiseless quantum amplifiers are probabilistic quantum devices that enhance amplitude of coherent states without adding any noise, which has far reaching applications in quantum op…
Experimental preparation of multiphoton-added coherent states of light
JiÅà Fadrný, Michal Neset, Martin Bielak +3
Conditional addition of photons represents a crucial tool for optical quantum state engineering and it forms a fundamental building block of advanced quantum photonic devices. Here…
