Quantum communications promises reliable transmission of quantum information, efficient distribution of entanglement and generation of completely secure keys. For all these tasks, we need to determine the optimal point-to-point rates that are achievable by two remote parties at the ends of a quantum channel, without restrictions on their local operations and classical communication, which can be unlimited and two-way. These two-way assisted capacities represent the ultimate rates that are… Expand
Energy-constrained two-way assisted private and quantum capacities of quantum channels
TLDR
It is proved that a thermal state maximizes a relaxation of the squashed entanglement of all phase-insensitive, single-mode input bosonic Gaussian channels, generalizing results from prior work and proving that a variation of the method introduced in Goodenough et al. leads to improved upper bounds on the energy-constrained secret-key-agreement capacity of a bosonic thermal channel.

It is shown that the secret key agreement capacity of a lossy and noisy optical channel assisted by unlimited two-way public classical communication is limited by an upper bound that is solely a function of the channel loss, regardless of how much optical power the protocol may use. Expand
Converse Bounds for Private Communication Over Quantum Channels
TLDR
This paper establishes several converse bounds on the private transmission capabilities of a quantum channel by using the notion of a private state along with a “privacy test” to establish a general meta-converse bound for private communication, which has a number of applications. Expand

TLDR
A protocol for coin-tossing by exchange of quantum messages is presented, which is secure against traditional kinds of cheating, even by an opponent with unlimited computing power, but ironically can be subverted by use of a still subtler quantum phenomenon, the Einstein-Podolsky-Rosen paradox.
