A scheme for generating Schrödinger-cat-like states of a single-mode optical field by means
of conditional measurement is proposed. Feeding a squeezed vacuum into a beam splitter …

In this volume, six review articles which cover a broad range of topics of current interest in
modern optics are included. The first article by S. Saltiel, AA Sukhorukov and YS Kivshar …

The subtraction or addition of a prescribed number of photons to a field mode does not, in
general, simply shift the probability distribution by the number of subtracted or added …

We show that conditional output measurement on a beam splitter may be used to produce
photon-added states for a large class of signal-mode quantum states, such as thermal …

State preparation via conditional output measurement on a beam splitter is studied,
assuming the signal mode is mixed with a mode prepared in a Fock state and photon …

The development of quantum information processing has traditionally followed two separate
and not immediately connected lines of study. The main line has focused on the …

We propose a scheme to prepare a macroscopic mechanical oscillator in a catlike state,
close to a coherent state superposition. The mechanical oscillator, coupled by radiation …

We investigate the possibility of implementing a given projection measurement using linear
optics and arbitrarily fast feedforward based on the continuous detection of photons. In …

State preparation via postselected weak measurements in a three-wave mixing process is
studied. We assume the signal input mode is prepared in a vacuum state, coherent state, or …

When an observation is carried out at one of the two output ports of a lossless beam splitter,
photon statistics of a conditional output state in the unobserved output port are investigated …
