Strong converse rates for classical communication over thermal and additive noise bosonic channels
Bhaskar Roy Bardhan, Mark M. Wilde
We prove that several known upper bounds on the classical capacity of thermal and additive noise bosonic channels are actually strong converse rates. Our results strengthen the int…
Robust quantum data locking from phase modulation
Cosmo Lupo, Mark M. Wilde, Seth Lloyd
Quantum data locking is a unique quantum phenomenon that allows a relatively short key to (un)lock an arbitrarily long message encoded in a quantum state, in such a way that an eav…
Multiplicativity of completely bounded -norms implies a strong converse for entanglement-assisted capacity
Manish K. Gupta, Mark M. Wilde
The fully quantum reverse Shannon theorem establishes the optimal rate of noiseless classical communication required for simulating the action of many instances of a noisy quantum…
Noise and disturbance in quantum measurements: an information-theoretic approach
Francesco Buscemi, Michael J. W. Hall, Masanao Ozawa +1
We introduce information-theoretic definitions for noise and disturbance in quantum measurements and prove a state-independent noise-disturbance tradeoff relation that these quanti…
The squashed entanglement of a quantum channel
Masahiro Takeoka, Saikat Guha, Mark M. Wilde
This paper defines the squashed entanglement of a quantum channel as the maximum squashed entanglement that can be registered by a sender and receiver at the input and output of a…
Strong converse for the classical capacity of the pure-loss bosonic channel
Mark M. Wilde, Andreas Winter
This paper strengthens the interpretation and understanding of the classical capacity of the pure-loss bosonic channel, first established in [Giovannetti et al., Physical Review Le…
