Orbital angular momentum modes of high-gain parametric down-conversion
Lina Beltran, Gaetano Frascella, Angela M. Perez +6
Light beams with orbital angular momentum (OAM) are convenient carriers of quantum information. They can be also used for imparting rotational motion to particles and provide high…
High-Dimensional Intra-City Quantum Cryptography with Structured Photons
Alicia Sit, Frédéric Bouchard, Robert Fickler +11
Quantum key distribution (QKD) promises information-theoretically secure communication, and is already on the verge of commercialization. Thus far, different QKD protocols have bee…
Exotic Looped Trajectories of Photons in Three-Slit Interference
Omar S. Magana-Loaiza, Israel De Leon, Mohammad Mirhosseini +8
The validity of the superposition principle and of Born's rule are well-accepted tenants of quantum mechanics. Surprisingly, it has recently been predicted that the intensity patte…
High-dimensional quantum cloning and applications to quantum hacking
Frédéric Bouchard, Robert Fickler, Robert W Boyd +1
Attempts at cloning a quantum system result in the introduction of imperfections in the state of the copies. This is a consequence of the no-cloning theorem, which is a fundamental…
Quantum entanglement of angular momentum states with quantum numbers up to 10010
Robert Fickler, Geoff T. Campbell, Ben C. Buchler +2
Photons with a twisted phase front carry a quantized amount of orbital angular momentum (OAM) and have become important in various fields of optics, such as quantum and classical i…
