“…In opto-mechanical systems, the idea consists of amplifying the "momentum-kick" given by a single photon to a micro-nano mechanical oscillator using a filter or a postselection procedure, i.e., to enlarge the radiation pressure effect of a single photon. There have been different theoretical proposals [26][27][28][29][30][31][32][33], and here we focus the analysis on a "standard" opto-mechanical system inserted in one of the arms of a Mach-Zehnder interferometer (labeled as arm 1), while a conventional Fabry-Pérot cavity is inserted in the other arm (labeled as arm 2). The setup is shown in Figure 3.…”

A measurement of an observable A performed on a quantum system that is initially prepared in a state ρi, followed by a probabilistic procedure that leaves the system in a final state ρf, a process often referred as state postselection (or filtering process), can yield, on average, anomalous measurement results, i.e., values that may exceed the eigenvalue range of the observable being measured or be complex numbers. There is, therefore, an amplification effect of the average measurement result, i.e., the effect of the system on the measurement device is increased. When the coupling between the system and the measurement device satisfies some weakness conditions, the amplification effect occurs due to the weak value of the operator A. In this article, the amplification effect due to the postselection process is reviewed, and theoretical proposals and experiments published in the recent literature on the field are commented on. The emphasis is made on interactions occurring in optical nonlinear media and opto-mechanical and spin-mechanical systems, in which the amplification of number operators takes place.

“…We highlight the increasing interest in the systems of optomechanical networks due to their wide spectrum of applications [34][35][36][37][38]. For example, the double-cavity, also known as a mirror-in-the-middle optomechanical system, can be considered the simplest type of network and was studied in various proposals [22,[39][40][41][42][43][44]. In the present work, we will consider a kind of double-cavity optomechanical system with its movable middle mirror (the mechanical oscillator), but there is no transmission of the light field through the mirror.…”

We present a systematic study on the effects of dynamical transfer and steady-state synchronization of quantum states in a hybrid optomechanical network consisting of two cavities, which carry atoms inside and interact via a common moving mirror such as the mechanical oscillator. It is found that a high fidelity transfer of Schrödinger’s cat and squeezed states between two cavities modes is possible. On the other hand, we demonstrate the synchronization effect of the cavity modes in a steady squeezed state with its high fidelity realized by the mechanical oscillator that intermediates the generation, transfer and stabilization of the squeezing. In this framework, we also study the generation and evolution of bipartite and tripartite entanglement and find its connection to the effects of quantum state transfer and synchronization. Particularly, when the transfer occurs at the maximal fidelity, any entanglement is almost zero, so the different cavity modes are disentangled. However, these modes become entangled when the two bosonic modes are synchronized in a stationary squeezed state. The results provided by the current study may find applications in quantum information technologies, in addition to the setups for metrology, where squeezed states are essential.
