Comparative case study into the barriers that prevent QKD and Tokamak nuclear fusion power plants from large scale diffusion

This research has the aim to investigate the large pre-diffusion period for two<br/>technologies: quantum cryptography and nuclear fusion power plants. Both technologies originate from basic physics research, have a high societal value and are a business to business product. First, a status overview of the technologies is given together with its...

Verifiable hybrid secret sharing in the presence of noise

Verifiable quantum secret sharing (VQSS) is the task of sharing a secret quantum state among the n nodes of a quantum network, in a way that it is possible to verify that the secret has been correctly distributed. A number of protocols that perform this task have been proposed. In particular, the verifiable hybrid secret sharing (VHSS) scheme...

Device Independent Quantum Key Distribution in the Finite Key Regime

Relaxing the assumptions about the experimental setup in Quantum Key Distribution protocols lays the foundation for Device Independent Quantum Key Distribution (DIQKD). In the finite key regime of DIQKD, the protocols employ the use of only the CHSH inequality, so far. A natural question therefore arises whether are there other Bell inequalities...
