Quantum data locking for high-rate private communication
Cosmo Lupo, Seth Lloyd
We show that, if the accessible information is used as a security quantifier, quantum channels with a certain symmetry can convey private messages at a tremendously high rate, as h…
Quantum brachistochrone curves as geodesics: obtaining accurate control protocols for time-optimal quantum gates
Xiaoting Wang, Michele Allegra, Kurt Jacobs +3
Most methods of optimal control cannot obtain accurate time-optimal protocols. The quantum brachistochrone equation is an exception, and has the potential to provide accurate time-…
Quantum-locked key distribution at nearly the classical capacity rate
Cosmo Lupo, Seth Lloyd
Quantum data locking is a protocol that allows for a small secret key to (un)lock an exponentially larger amount of information, hence yielding the strongest violation of the class…
Entanglement Typicality
Oscar C. O. Dahlsten, Cosmo Lupo, Stefano Mancini +1
We provide a summary of both seminal and recent results on typical entanglement. By typical values of entanglement, we refer here to values of entanglement quantifiers that (given…
Theory of filtered type-II PDC in the continuous-variable domain: Quantifying the impacts of filtering
Andreas Christ, Cosmo Lupo, Matthias Reichelt +2
Parametric down-conversion (PDC) forms one of the basic building blocks for quantum optical experiments. However, the intrinsic multimode spectral-temporal structure of pulsed PDC…
Maximally strong entropic uncertainty relations and gauge invariance
Cosmo Lupo, Seth Lloyd
Uncertainty relations are among the unique fingerprints of quantum physics, being direct expression of non-commutativity and complementarity. Entropic uncertainty relations arise i…
