Super-Resolution Quantum Imaging at the Heisenberg Limit
Manuel Unternährer, Bänz Bessire, Leonardo Gasparini +2
Quantum imaging exploits the spatial correlations between photons to image object features with a higher resolution than a corresponding classical light source could achieve. Using…
Experimental violation of a d-dimensional Bell inequality using energy-time entangled photons
Sacha Schwarz, Bänz Bessire, André Stefanov
We experimentally study the violation of the CGLMP inequality for entangled 2-qubit and 2-qutrit states with different degrees of entanglement using numerically optimized measureme…
Tuning curve of type-0 spontaneous parametric down-conversion
Stefan Lerch, Bänz Bessire, Christof Bernhard +2
We study the tuning curve of entangled photons generated by type-0 spontaneous parametric down-conversion in a periodically poled KTP crystal. We demonstrate the X-shaped spatiotem…
Shaping frequency entangled qudits
Christof Bernhard, Bänz Bessire, Thomas Feurer +1
Quantum entanglement between qudits - the d-dimensional version of qubits - is relevant for advanced quantum information processing and provides deeper insights in the nature of qu…
Systematic Low-Energy Effective Field Theory for Magnons and Holes in an Antiferromagnet on the Honeycomb Lattice
F. Kämpfer, B. Bessire, M. Wirz +3
Based on a symmetry analysis of the microscopic Hubbard and t-J models, a systematic low-energy effective field theory is constructed for hole-doped antiferromagnets on the honeyco…
