“…One can then even think of creating entangled states at high, but clearly defined photon numbers, the so-called high-noon states [31][32][33] [a pun on the notation ðjNij0i þ j0ijNiÞ]. These are of fundamental interest and have applications in measurements that beat the wavelength resolution limit.…”

An x-ray free-electron laser oscillator (XFELO) is a next-generation x-ray source, similar to free-electron laser oscillators at VUV and longer wavelengths but using crystals as high-reflectivity x-ray mirrors. Each output pulse from an XFELO is fully coherent with high spectral purity. The temporal coherence length can further be increased drastically, from picoseconds to microseconds or even longer, by phase-locking successive XFELO output pulses, using the narrow nuclear resonance lines of nuclei such as 57 Fe as a reference. We show that the phase fluctuation due to the seismic activities is controllable and that due to spontaneous emission is small. The fluctuation of electron-bunch spacing contributes mainly to the envelope fluctuation but not to the phase fluctuation. By counting the number of standing-wave maxima formed by the output of the nuclear-resonance-stabilized (NRS) XFELO over an optically known length, the wavelength of the nuclear resonance can be accurately measured, possibly leading to a new length or frequency standard at x-ray wavelengths. A NRS-XFELO will be an ideal source for experimental x-ray quantum optics as well as other fundamental physics. The technique can be refined for other, narrower resonances such as 181 Ta or 45 Sc.

“…It was shown recently that these states may be conditionally generated with the help of linear optics, single photon sources and photodetectors [14,15,16,17]. We then combine the modes 1 and 2 on a balanced beam splitter and measure the number of photons in output modes 1 and 2 by means of two photodetectors P D 1 and P D 2 with single-photon resolution.…”

“…Schemes for probabilistic preparation of Fock states [9], arbitrary superpositions of Fock states of single-mode field [10,11], and superpositions of classically distinguishable states (Schrödinger-cat-like states) [12,13], have been found. Several setups for the generation of twomode N -photon path-entangled states have been suggested [14,15,16,17,18]. Recently, the experimental conditional preparation of a single-photon Fock state with negative Wigner function has been reported [19].…”

We propose a universal scheme for the probabilistic generation of an arbitrary multimode entangled state of light with finite expansion in Fock basis. The suggested setup involves passive linear optics, single photon sources, strong coherent laser beams, and photodetectors with single-photon resolution. The efficiency of this setup may be greatly enhanced if, in addition, a quantum memory is available.

“…In their reply (Bouwmeester et al Nature, 1998), they point out that the situation should be interpreted as reducing the efficiency of teleportation rather than its quality. Possible solutions (Braunstein and Kimble, 1998;Kok and Braunstein, 2000) could include the discrimination of one-and two-photon events at detector p [ Fig. 21(b)], a quantum non-demolition measurement of the photon number in mode 3.…”

Multi-photon interference reveals strictly non-classical phenomena. Its applications range from fundamental tests of quantum mechanics to photonic quantum information processing, where a significant fraction of key experiments achieved so far comes from multi-photon state manipulation. We review the progress, both theoretical and experimental, of this rapidly advancing research. The emphasis is given to the creation of photonic entanglement of various forms, tests of the completeness of quantum mechanics (in particular, violations of local realism), quantum information protocols for quantum communication (e.g., quantum teleportation, entanglement purification and quantum repeater), and quantum computation with linear optics. We shall limit the scope of our review to "few photon" phenomena involving measurements of discrete observables.
