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…
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…
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…
