Experimental determination of the degree of quantum polarisation of continuous variable states
Christian Kothe, Lars Skovgaard Madsen, Ulrik Lund Andersen +1
We demonstrate excitation-manifold resolved polarisation characterisation of continuous-variable (CV) quantum states. In contrast to traditional characterisation of polarisation th…
Central-moment description of polarization for quantum states of light
G. Björk, J. Söderholm, Y. -S. Kim +6
We present a moment expansion method for the systematic characterization of the polarization properties of quantum states of light. Specifically, we link the method to the measurem…
On the efficiency of quantum lithography
Christian Kothe, Gunnar Björk, Shuichiro Inoue +1
Quantum lithography promises, in principle, unlimited feature resolution, independent of wavelength. However, in the literature at least two different theoretical descriptions of q…
Arbitrarily High Super-Resolving Phase Measurements at Telecommunication Wavelengths
Christian Kothe, Gunnar Björk, Mohamed Bourennane
We present two experiments that achieve phase super-resolution at telecommunication wavelengths. One of the experiments is realized in the space domain and the other in the time do…
Entanglement quantification through local observable correlations
Christian Kothe, Gunnar Björk
We present a significantly improved scheme of entanglement detection inspired by local uncertainty relations for a system consisting of two qubits. Developing the underlying idea o…
