9 Sep 2015 | | Abstract: | The power of optical holography stems from its ability to reveal complete,
phase-amplitude spatial information about detected light. Standard holographic
methods require a well-defined phase relation between measured and reference
beams that is fundamentally impossible to fulfill for a single photon due to
its entirely indeterminate global phase. We introduce a method to create a
hologram of a single photon (HSP) probed by a reference photon, based on an
essentially different concept of quantum interference between two-photon
probability amplitudes. Similarly to classical holograms, HSP encodes full
information about photon’s "shape", i.e. its quantum wavefunction whose local
amplitude and phase are retrieved in the presented experiment. The HSP
technique can be applied also to measure wavefunctions of other bosons, such as
integer spin atoms. | | Source: | arXiv, 1509.2890 | | Services: | Forum | Review | PDF | Favorites | |
