On the resolution of quantum paradoxes by weak measurements
Holger F. Hofmann
In this presentation, I argue that weak measurements empirically support the notion of quantum superpositions as statistical alternatives. In short, weak measurements show that Sch…
Effects of photon losses on phase estimation near the Heisenberg limit using coherent light and squeezed vacuum
Takafumi Ono, Holger F. Hofmann
Two path interferometry with coherent states and squeezed vacuum can achieve phase sensitivities close to the Heisenberg limit when the average photon number of the squeezed vacuum…
Directional emission of light from a nano-optical Yagi-Uda antenna
Terukazu Kosako, Holger F. Hofmann, Yutaka Kadoya
The plasmon resonance of metal nanoparticles can enhance and direct light from optical emitters in much the same way that radio frequency (RF) antennas enhance and direct the emiss…
Reconstruction of spatial qutrit states based on realistic measurement operators
Gen Taguchi, Tatsuo Dougakiuchi, Masataka Iinuma +2
Spatial qudit states can be realized by using multi-slits to discretize the transverse momentum of a photon. The merit of this kind of spatial qudit states is that the implementati…
Complete characterization of post-selected quantum statistics using weak measurement tomography
Holger F. Hofmann
The reconstruction of quantum states from a sufficient set of experimental data can be achieved with arbitrarily weak measurement interactions. Since such weak measurements have ne…
Pulse shape effects on photon-photon interactions in non-linear optical quantum gates
Holger F. Hofmann, Hitoshi Nishitani
Ideally, strong non-linearities could be used to implement quantum gates for photonic qubits by well controlled two photon interactions. However, the dependence of the non-linear i…
An Entanglement Filter
Ryo Okamoto, Jeremy L. O'Brien, Holger F. Hofmann +3
The ability to filter quantum states is a key capability in quantum information science and technology, in which one-qubit filters, or polarizers, have found wide application. Filt…
