On the existence of fully inseparable biseparable Gaussian states
Olga Leskovjanová, Klára Baksová, Jan ProvaznÃk +2
Genuine multipartite entanglement and full inseparability are two inequivalent quantum resources. Even though all genuinely multipartite entangled states are also fully inseparable…

Quantum-limited detection of arrival time and carrier frequency of time-dependent signals
Patrick Folge, Laura Serino, Ladislav Mišta +4
Precise measurements of both the arrival time and carrier frequency of light pulses are essential for time-frequency-encoded quantum technologies. Quantum mechanics, however, impos…

Experimental verification of multi-copy activation of genuine multipartite entanglement
Robert Stárek, Tim Gollerthan, Olga Leskovjanová +5
A central concept in quantum information processing is genuine multipartite entanglement (GME), a type of correlation beyond biseparability, that is, correlations that cannot be ex…
