Quantum Subdivision Capacities and Continuous-time Quantum Coding
Alexander Müller-Hermes, David Reeb, Michael M. Wolf
Quantum memories can be regarded as quantum channels that transmit information through time without moving it through space. Aiming at a reliable storage of information we may thus…
Coexistence does not imply joint measurability
David Reeb, Daniel Reitzner, Michael M. Wolf
One of the hallmarks of quantum theory is the realization that distinct measurements cannot in general be performed simultaneously, in stark contrast to classical physics. In this…
Fault-ignorant Quantum Search
Peter Vrana, David Reeb, Daniel Reitzner +1
We investigate the problem of quantum searching on a noisy quantum computer. Taking a 'fault-ignorant' approach, we analyze quantum algorithms that solve the task for various diffe…
An improved Landauer Principle with finite-size corrections
David Reeb, Michael M. Wolf
Landauer's Principle relates entropy decrease and heat dissipation during logically irreversible processes. Most theoretical justifications of Landauer's Principle either use therm…
Entanglement witnessing in superconducting beamsplitters
H. Soller, L. Hofstetter, D. Reeb
We analyse a large class of superconducting beamsplitters for which the Bell parameter (CHSH violation) is a simple function of the spin detector efficiency. For these superconduct…
Tight bound on relative entropy by entropy difference
David Reeb, Michael M. Wolf
We prove a lower bound on the relative entropy between two finite-dimensional states in terms of their entropy difference and the dimension of the underlying space. The inequality…
