Tunable quantum interference: How to make morning, noon, and afternoon states
Holger F. Hofmann, Takafumi Ono
We show that the N-photon states produced by interference between laser light and downconverted light at the input of a two path interferometer can be characterized by a single tun…
Quantum enhancement of N-photon phase sensitivity by interferometric addition of down-converted photon pairs to weak coherent light
Takafumi Ono, Holger F. Hofmann
It is shown that the addition of down-converted photon pairs to coherent laser light enhances the N-photon phase sensitivity due to the quantum interference between components of t…
High photon number path entanglement in the interference of spontaneously downconverted photon pairs with coherent laser light
Holger F. Hofmann, Takafumi Ono
We show that the quantum interference between downconverted photon pairs and photons from coherent laser light can produce a maximally path entangled N-photon output component with…
Accidental cloning of a single-photon qubit in two-channel continuous-variable quantum teleportation
Toshiki Ide, Holger F. Hofmann
The information encoded in the polarization of a single photon can be transferred to a remote location by two-channel continuous-variable quantum teleportation. However, the finite…
