Mutual information of optical communication in phase conjugating Gaussian channels
Clemens Schäfermeier, Ulrik L. Andersen
In all practical communication channels, the code word consist of Gaussian states and the measurement strategy is often a Gaussian detector such as homodyning or heterodyning. In t…
Practical quantum computing on encrypted data
Kevin Marshall, Christian S. Jacobsen, Clemens Schafermeier +3
The ability to perform computations on encrypted data is a powerful tool for protecting a client's privacy, especially in today's era of cloud and distributed computing. In terms o…
