The Pegg-Barnett phase operator and the discrete Fourier transform
A. Perez-Leija, L. A. Andrade-Morales, F. Soto-Eguibar +2
In quantum mechanics the position and momentum operators are related to each other via the Fourier transform. In the same way, here we show that the so-called Pegg-Barnett phase op…
Generalized Schrödinger cat states and their classical emulation
Armando Perez-Leija, Irán Ramos-Prieto, Alexander Szameit +2
We demonstrate that superpositions of coherent and displaced Fock states, also referred to as generalized Schrödinger cats cats, can be created by application of a nonlinear displa…
Demonstration of local teleportation using classical entanglement
Diego Guzman-Silva, Robert Brüning, Felix Zimmermann +8
Teleportation is the most widely discussed application of the basic principles of quantum mechanics. Fundamentally, this process describes the transmission of information, which in…
Implementation of Quantum and Classical Discrete Fractional Fourier Transforms
Steffen Weimann, Armando Perez-Leija, Maxime Lebugle +9
Fourier transforms are ubiquitous mathematical tools in basic and applied sciences. We here report classical and quantum optical realizations of the discrete fractional Fourier tra…
Enhancing quantum transport in a photonic network using controllable decoherence
Devon N. Biggerstaff, René Heilmann, Aidan A. Zecevik +7
Transport phenomena on a quantum scale appear in a variety of systems, ranging from photosynthetic complexes to engineered quantum devices. It has been predicted that the efficienc…
Divide-and-Conquer: An integrated photon-counting scheme
Rene Heilmann, Jan Sperling, Armando Perez-Leija +5
The key requirement for harnessing the quantum properties of light is the capability to detect and count individual photons. Of particular interest are photon-number-resolving dete…
