Sensing rotations with multiplane light conversion
M. Eriksson, A. Z. Goldberg, M. Hiekkamäki +4
We report an experiment estimating the three parameters of a general rotation. The scheme uses quantum states attaining the ultimate precision dictated by the quantum Cramér-Rao bo…
High-efficiency interface between multi-mode and single-mode fibers
Oussama Korichi, Markus Hiekkamäki, Robert Fickler
Multi-mode fibers (MMFs) and single-mode fibers (SMFs) are widely used in optical communication networks. MMFs are the practical choice in terms of cost in applications that requir…
Observation of the quantum Gouy phase
Markus Hiekkamäki, Rafael F. Barros, Marco Ornigotti +1
Controlling the evolution of a photonic quantum states is crucial for most quantum information processing and metrology tasks. Because of its importance, many mechanisms of quantum…
Quantum advantage using high-dimensional twisted photons as quantum finite automata
Stephen Z. D. Plachta, Markus Hiekkamäki, Abuzer Yakaryılmaz +1
Quantum finite automata (QFA) are basic computational devices that make binary decisions using quantum operations. They are known to be exponentially memory efficient compared to t…
Robust quantum metrology with random Majorana constellations
A. Z. Goldberg, J. R. Hervas, Ángel S Sanz +8
Even the most classical states are still governed by quantum theory. A number of physical systems can be described by their Majorana constellations of points on the surface of a sp…
Talbot self-imaging and two-photon interference in ring-core fibers
Matias Eriksson, Benjamin A. Stickler, Lea Kopf +5
Wave propagation on the surface of cylinders exhibits interferometric self imaging, much like the Talbot effect in the near-field diffraction at periodic gratings. We report the ex…
Endless Fun in high dimensions -- A Quantum Card Game
Lea Kopf, Markus Hiekkamäki, Shashi Prabhakar +1
Quantum technologies, i.e., technologies benefiting from the features of quantum physics such as objective randomness, superposition, and entanglement, have enabled an entirely dif…
Photonic angular super-resolution using twisted N00N states
Markus Hiekkamäki, Frédéric Bouchard, Robert Fickler
The increased phase sensitivity of N00N states has been used in many experiments, often involving photon paths or polarization. Here we experimentally combine the phase sensitivity…
