Quantum Theory Looks at Time Travel
Daniel M. Greenberger, Karl Svozil
We introduce a quantum mechanical model of time travel which includes two figurative beam splitters in order to induce feedback to earlier times. This leads to a unique solution to…
Characterization of quantum computable decision problems by state discrimination
Karl Svozil
One advantage of quantum algorithms over classical computation is the possibility to spread out, process, analyse and extract information in multipartite configurations in coherent…
On the plasticity of nonlocal quantum correlations
Karl Svozil
The quantum correlations of two or more entangled particles present the possibility of stronger-than-classical outcome coincidences. We investigate two-partite correlations of spin…
Feasibility of the interlock protocol against man-in-the-middle attacks on quantum cryptography
Karl Svozil
If an eavesdropper succeeds in compromising the quantum as well as the classical channels and mimics the receiver "Bob" for the sender "Alice" and vice versa, one defence strategy…
