Journal ArticleDOI
Laser written circuits for quantum photonics
Thomas Meany,Thomas Meany,Markus Gräfe,René Heilmann,Armando Perez-Leija,Simon Gross,Michael J. Steel,Michael J. Withford,Alexander Szameit +8 more
TL;DR: The femtosecond laser direct-writing of waveguide circuits in glasses is among the few integrated optical platforms to have produced individually every component required for scalable quantum computation.
Journal ArticleDOI
Coherent quantum transport in photonic lattices
Armando Perez-Leija,Robert Keil,Alastair Kay,Alastair Kay,Héctor M. Moya-Cessa,Stefan Nolte,Leong Chuan Kwek,Leong Chuan Kwek,B. M. Rodríguez-Lara,Alexander Szameit,Demetrios N. Christodoulides +10 more
TL;DR: This work reports on an observation of a perfect state transfer protocol on a lattice, thereby demonstrating the general concept of transporting arbitrary quantum information with high fidelity, and provides unequivocal evidence that such an approach is applicable in the quantum regime.
Journal ArticleDOI
Anderson localization in optical waveguide arrays with off-diagonal coupling disorder
Lane Martin,Giovanni Di Giuseppe,Armando Perez-Leija,Robert Keil,Felix Dreisow,Matthias Heinrich,Stefan Nolte,Alexander Szameit,Ayman F. Abouraddy,Demetrios N. Christodoulides,Bahaa E. A. Saleh +10 more
TL;DR: It is observed that the transition from extended to Anderson-localized states in silica waveguide arrays exhibiting off-diagonal coupling disorder is observed.
Journal ArticleDOI
On-chip generation of high-order single-photon W-states
Markus Gräfe,René Heilmann,Armando Perez-Leija,Robert Keil,Robert Keil,Felix Dreisow,Matthias Heinrich,Matthias Heinrich,Héctor M. Moya-Cessa,Stefan Nolte,Demetrios N. Christodoulides,Alexander Szameit +11 more
TL;DR: In this article, a scheme capable of exploiting the maximal entanglement of W-states is proposed for the efficient generation of random numbers, which can be used to generate random numbers with equal probability amplitudes.
Journal ArticleDOI
Implementation of quantum and classical discrete fractional Fourier transforms.
Steffen Weimann,Armando Perez-Leija,Maxime Lebugle,Robert Keil,Malte C. Tichy,Markus Gräfe,René Heilmann,Stefan Nolte,Héctor M. Moya-Cessa,Gregor Weihs,Demetrios N. Christodoulides,Alexander Szameit +11 more
TL;DR: In the context of classical optics, this work implements discrete fractional Fourier transforms of exemplary wave functions and experimentally demonstrate the shift theorem and applies this approach in the quantum realm to Fourier transform separable and path-entangled biphoton wave functions.
