Cross-verification of independent quantum devices
C. Greganti, T. F. Demarie, M. Ringbauer +13
Quantum computers are on the brink of surpassing the capabilities of even the most powerful classical computers. This naturally raises the question of how one can trust the results…
Experimental few-copy multi-particle entanglement detection
Valeria Saggio, Aleksandra Dimić, Chiara Greganti +3
Quantum technologies lead to a variety of applications that outperform their classical counterparts. In order to build a quantum device it must be verified that it operates below s…
Tapering of fs Laser-written Waveguides
René Heilmann, Chiara Greganti, Markus Gräfe +3
The vast development of integrated quantum photonic technology enables the implementation of compact and stable interferometric networks. In particular laser-written waveguide stru…
Numerical Investigation of Photon-Pair Generation in Periodically Poled MTiOXO4 (M = K, Rb, Cs; X = P, As)
Fabian Laudenbach, Rui-Bo Jin, Chiara Greganti +3
We present a detailed numerical investigation of five nonlinear materials and their properties regarding photon-pair creation using parametric downconversion. Periodic poling of fe…
Demonstration of measurement-only blind quantum computing
Chiara Greganti, Marie-Christine Roehsner, Stefanie Barz +2
Blind quantum computing allows for secure cloud networks of quasi-classical clients and a fully fledged quantum server. Recently, a new protocol has been proposed, which requires a…
Practical and efficient experimental characterization of multiqubit stabilizer states
Chiara Greganti, Marie-Christine Roehsner, Stefanie Barz +2
Vast developments in quantum technology have enabled the preparation of quantum states with more than a dozen entangled qubits. The full characterization of such systems demands di…
Demonstrating an element of measurement-based quantum error correction
Stefanie Barz, Rui Vasconcelos, Chiara Greganti +4
In measurement-based quantum computing an algorithm is performed by measurements on highly-entangled resource states. To date, several implementations were demonstrated, all of the…
Linear Optics Simulation of Non-Markovian Quantum Dynamics
Andrea Chiuri, Chiara Greganti, Laura Mazzola +2
The simulation of quantum processes is a key goal for the grand programme aiming at grounding quantum technologies as the way to explore complex phenomena that are inaccessible thr…
Engineering a C-Phase quantum gate: optical design and experimental realization
Andrea Chiuri, Chiara Greganti, Paolo Mataloni
A two qubit quantum gate, namely the C-Phase, has been realized by exploiting the longitudinal momentum (i.e. the optical path) degree of freedom of a single photon. The experiment…
Experimental Quantum Networking Protocols via Four-Qubit Hyperentangled Dicke States
A. Chiuri, C. Greganti, M. Paternostro +2
We report the experimental demonstration of two quantum networking protocols, namely quantum 1->3 telecloning and open-destination teleportation, implemented using a four-qubit reg…
