We introduce and experimentally demonstrate a self-referenced interferometric technique which enables complete characterization of an arbitrary 2D spatial structure of a single photon relying on the fact that a single photon can interfere with itself.

Hologram of a single photon
The local amplitude and phase of a single photon is retrieved using a method similar to classical holography. The interference of optical fields is replaced by the non-classical interference of
Entangled-photon imaging of a pure phase object.
It is demonstrated experimentally and theoretically that a coherent image of a pure phase object may be obtained by use of a spatially incoherent illumination beam by employing a two-beam source of entangled photons generated by spontaneous parametric down-conversion.
Self-referenced hologram of a single photon beam
Quantitative characterization of the spatial structure of single photons is essential for free-space quantum communication and quantum imaging. We introduce an interferometric technique that enables
Measuring the Single-Photon Temporal-Spectral Wave Function.
An optical reference-free method is demonstrated, which melds techniques from ultrafast metrology and single-photon spectral detection, to characterize the pulse-mode structure of heralded single photons.
Measurement of the transverse spatial quantum state of light at the single-photon level.
The technique provides a large numerical aperture without distorting the shape of the wavefront, does not introduce astigmatism, and allows for characterization of fully or partially coherent optical fields at the single-photon level.
A wavefront shearing interferometer
A new type of interferometer is described by means of which the asphericity of an optical wavefront can be measured, by testing it against itself with lateral displacement or shear. Continuous
Measurement of subpicosecond time intervals between two photons by interference.
A fourth-order interference technique has been used to measure the time intervals between two photons, and by implication the length of the photon wave packet, produced in the process of parametric
High-fidelity spatially resolved multiphoton counting for quantum imaging applications.
Investigation operation is reliable for illumination levels up to the average of one detected photon per an event area-substantially higher than in previous approaches to characterize quantum statistical properties of light with spatial resolution.
Optical phase retrieval by phase-space tomography and fractional-order Fourier transforms.
Phase-space tomography is experimentally demonstrated for the determination of the spatially varying amplitude and phase of a quasi-monochromatic optical field by measurements of intensity only. Both
Beating the Rayleigh Limit Using Two-Photon Interference.
It is shown, theoretically and experimentally, that Hong-Ou-Mandel interference followed by spatially resolved detection of photons provides precise information on both the separation and the centroid for a pair of point emitters, avoiding trade-offs inherent to single-photon measurements.
