Conclusive quantum steering with superconducting transition edge sensors
Devin H. Smith, Geoff Gillett, Marcelo de Almeida +9
Quantum steering allows two parties to verify shared entanglement even if one measurement device is untrusted. A conclusive demonstration of steering through the violation of a ste…
Reducing multi-photon rates in pulsed down-conversion by temporal multiplexing
Matthew A. Broome, Marcelo P. Almeida, Alessandro Fedrizzi +1
We present a simple technique to reduce the emission rate of higher-order photon events from pulsed spontaneous parametric down-conversion. The technique uses extra-cavity control…
Polarization-entanglement conserving frequency conversion of photons
Sven Ramelow, Alessandro Fedrizzi, Andreas Poppe +2
Entangled photons play a pivotal role in the distribution of quantum information in quantum networks. However, the frequency bands for optimal transmission and storage of photons a…
Observation of topologically protected bound states in a one dimensional photonic system
Takuya Kitagawa, Matthew A. Broome, Alessandro Fedrizzi +6
One of the most striking features of quantum mechanics is the appearance of phases of matter with topological origins. These phases result in remarkably robust macroscopic phenomen…
Two-photon quantum walks in an elliptical direct-write waveguide array
J. O. Owens, M. A. Broome, D. N. Biggerstaff +8
Integrated optics provides an ideal test bed for the emulation of quantum systems via continuous-time quantum walks. Here we study the evolution of two-photon states in an elliptic…
Entanglement dynamics and quasi-periodicity in discrete quantum walks
Peter P. Rohde, Alessandro Fedrizzi, Timothy C. Ralph
We study the entanglement dynamics of discrete time quantum walks acting on bounded finite sized graphs. We demonstrate that, depending on system parameters, the dynamics may be mo…
