Nonadditivity of quantum capacity for multiparty communication channels.
We investigate multiparty communication scenarios where information is sent from several senders to several receivers. We establish a relation between the quantum capacity of multiparty communication channels and their distillability properties, which enables us to show that the quantum capacity of such channels is not additive.
متن کاملMultiparty Quantum Communication Complexity
Quantum entanglement cannot be used to achieve direct communication between remote parties, but it can reduce the communication needed for some problems. Let each of k parties hold some partial input data to some fixed k-variable function f . The communication complexity of f is the minimum number of classical bits required to be broadcasted for every party to know the value of f on their input...
متن کاملQuantum communication with zero-capacity channels.
Communication over a noisy quantum channel introduces errors in the transmission that must be corrected. A fundamental bound on quantum error correction is the quantum capacity, which quantifies the amount of quantum data that can be protected. We show theoretically that two quantum channels, each with a transmission capacity of zero, can have a nonzero capacity when used together. This unveils...
متن کاملMultiparty Quantum Communication Complexity of Triangle Finding
Triangle finding (deciding if a graph contains a triangle or not) is a central problem in quantum query complexity. The quantum communication complexity of this problem, where the edges of the graph are distributed among the players, was considered recently by Ivanyos et al. in the twoparty setting. In this paper we consider its k-party quantum communication complexity with k ≥ 3. Our main resu...
متن کاملSecure Communication over Zero-Private Capacity Quantum Channels
In this work a new phenomenon called polaractivation is introduced. Polaractivation is based on quantum polar encoding and the result is similar to the superactivation effect — positive capacity can be achieved with zero-capacity quantum channels. However, polaractivation has many advantages over the superactivation: it is limited neither by any preliminary conditions on the quantum channel nor...
