Continuous Variable Quantum Cryptography using Two-Way Quantum Communication
Stefano Pirandola, Stefano Mancini, Seth Lloyd +1
Quantum cryptography has been recently extended to continuous variable systems, e.g., the bosonic modes of the electromagnetic field. In particular, several cryptographic protocols…
ε-convertibility of entangled states and extension of Schmidt rank in infinite-dimensional systems
Masaki Owari, Samuel L. Braunstein, Kae Nemoto +1
By introducing the concept of -convertibility, we extend Nielsen's and Vidal's theorems to the entanglement transformation of infinite-dimensional systems. Using an infinite-dim…
Quantum information cannot be completely hidden in correlations: implications for the black-hole information paradox
Samuel L. Braunstein, Arun K. Pati
The black-hole information paradox has fueled a fascinating effort to reconcile the predictions of general relativity and those of quantum mechanics. Gravitational considerations t…
