“…The quantum scissors have been discussed in detail in several recent papers [34,35,36,37,38]. The schemes proposed there can be implemented with the use of linear optics, single photon sources, and photodetectors.…”

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.

“…We do so with the help of the quantum scissors [34,35,36,37,38] that will project the state in the mode 1 onto the subspace spanned by the first N + 1 Fock states. This action is formally described by the projector Π QS = N n=0 |n n|.…”

A non-Gaussian state being a mixture of the vacuum and single-photon states can be generated by truncating a thermal state in a quantum scissors device of Pegg et al. [Phys. Rev. Lett. 81 (1998) 1604. In contrast to the thermal state, the generated state shows nonclassical property including the negativity of Wigner function. Besides, signal amplification and signal-to-noise ratio enhancement can be achieved.

“…The optical state truncation scheme, which is also referred to as the quantum scissors device (QSD), was originally proposed for preparing superposition of vacuum and one-photon state by truncating a coherent light, and it has been modified by Koniorczyk et al [7] to generate superposition of vacuum, one-photon and two-photon states. The original QSD scheme is built by two beam splitters, one of which is fed by one-photon in one input port whereas the second port is left at vacuum.…”

“…Consequently, the quantum engineering of light, which consists of generation and measurement of non-classical states of the optical field, has seen a rapid development [1]. Several schemes, which include the Fock filtering scheme of D'Ariano et al [2], photon adding and displacing scheme of Dakna et al [3] and the optical state truncation of Pegg et al [4]- [7] have been proposed and studied.…”
