Multi-partite entanglement can speed up quantum key distribution in networks
New Journal of Physics, 2017 The laws of quantum mechanics allow for the distribution of a secret random key between two parties. Here we analyse the security of a protocol for establishing a common secret key between N parties (i.e.

Correlations in star networks: from Bell inequalities to network inequalities
New Journal of Physics, 2017 The problem of characterizing classical and quantum correlations in networks is considered. Contrary to the usual Bell scenario, where distant observers share a physical system emitted by one common source, a network features several independent sources,

Asynchronous reference frame agreement in a quantum network
New Journal of Physics, 2016 An efficient implementation of many multiparty protocols for quantum networks requires that all the nodes in the network share a common reference frame. Establishing such a reference frame from scratch is especially challenging in an asynchronous network

Spatial reference frame agreement in quantum networks
New Journal of Physics, 2014 In order to communicate information in a quantum network effectively, all network nodes should share a common reference frame. Here, we propose to study how well m nodes in a quantum network can establish a common spatial reference frame from scratch ...

High-dimensional quantum cryptography with twisted light
New Journal of Physics, 2015 Quantum key distribution (QKD) systems often rely on polarization of light for encoding, thus limiting the amount of information that can be sent per photon and placing tight bounds on the error rates that such a system can tolerate.

High-capacity quantum key distribution via hyperentangled degrees of freedom
New Journal of Physics, 2014 Quantum key distribution (QKD) has long been a promising area for the application of quantum effects in solving real-world problems. However, two major obstacles have stood in the way of its widespread application: low secure key generation rates and ...

Intensity modulation and direct detection quantum key distribution based on quantum noise
New Journal of Physics, 2016 Quantum key distribution (QKD) has been studied for achieving perfectly secure cryptography based on quantum mechanics. This paper presents a novel QKD scheme that is based on an intensity-modulation and direct-detection system.
