Basic exclusivity graphs in quantum correlations
Adan Cabello, Lars Eirik Danielsen, Antonio J. Lopez-Tarrida +1
A fundamental problem is to understand why quantum theory only violates some noncontextuality (NC) inequalities and identify the physical principles that prevent higher-than-quantu…
Experimental fully contextual correlations
Elias Amselem, Lars Eirik Danielsen, Antonio J. Lopez-Tarrida +3
Quantum correlations are contextual yet, in general, nothing prevents the existence of even more contextual correlations. We identify and test a noncontextuality inequality in whic…
Optimal preparation of graph states
Adan Cabello, Lars Eirik Danielsen, Antonio J. Lopez-Tarrida +1
We show how to prepare any graph state of up to 12 qubits with: (a) the minimum number of controlled-Z gates, and (b) the minimum preparation depth. We assume only one-qubit and co…
On Self-Dual Quantum Codes, Graphs, and Boolean Functions
Lars Eirik Danielsen
A short introduction to quantum error correction is given, and it is shown that zero-dimensional quantum codes can be represented as self-dual additive codes over GF(4) and also as…
