Quantum walks and wavepacket dynamics on a lattice with twisted photons
Filippo Cardano, Francesco Massa, Hammam Qassim +8
The "quantum walk" has emerged recently as a paradigmatic process for the dynamic simulation of complex quantum systems, entanglement production and quantum computation. Hitherto,…
Photonic quantum walk in a single beam with twisted light
Filippo Cardano, Francesco Massa, Ebrahim Karimi +6
Inspired by the classical phenomenon of random walk, the concept of quantum walk has emerged recently as a powerful platform for the dynamical simulation of complex quantum systems…
Free-space quantum key distribution by rotation-invariant twisted photons
Giuseppe Vallone, Vincenzo D'Ambrosio, Anna Sponselli +4
Twisted photons are photons carrying a well-defined nonzero value of orbital angular momentum (OAM). The associated optical wave exhibits a helical shape of the wavefront (hence th…
