Achieving the ultimate quantum timing resolution
Vahid Ansari, Benjamin Brecht, Jano Gil-López +5
Accurate time-delay measurement is at the core of many modern technologies. Here, we present a temporal-mode demultiplexing scheme that achieves the ultimate quantum precision for…
Spatial entanglement and state engineering via four-photon Hong-Ou-Mandel interference
A. Ferreri, V. Ansari, B. Brecht +2
The phenomenon of entanglement is the basis of quantum information and quantum communication processes. Entangled systems with a large number of photons are of great interest at pr…
Remotely projecting states of photonic temporal modes
Vahid Ansari, John M. Donohue, Benjamin Brecht +1
Two-photon time-frequency entanglement is a valuable resource in quantum information. Resolving the wavepacket of ultrashort pulsed single-photons, however, is a challenge. Here, w…
Counter-propagating photon pair generation in a nonlinear waveguide
Kai-Hong Luo, Vahid Ansari, Marcello Massaro +5
Counter-propagating parametric conversion processes in non-linear bulk crystals have been shown to feature unique properties for efficient narrowband frequency conversion. In quant…
