Special Issue Information

Dear Colleagues,

Hybrid systems are of paramount importance regarding the development of quantum technologies. In this direction, hybrid systems containing the elements of opto-mechanics (OM) or spin-mechanics (SM) become very attractive in realizing quantum tasks. Some time ago, OM and SM became emerging areas at the interface of fields such as quantum optics and information, mesoscopic physics, photonics, magnetism, etc., focusing on fundamental and applied research. In the fundamental direction, they play an important role in bringing the laws of quantum mechanics closer to the macroscopic world, such as through providing evidence of quantum properties with macroscopic systems to study the foundations of quantum mechanics. In addition, the OM and SM systems have become attractive for studies related to the gravitational effects, searching for bridges to interconnect the two important theories of modern physics: quantum mechanics and general relativity. In the context of applied research, there are innumerable possibilities for applications: for example, to improve the protocols of metrology, sensing and precision, or to develop new techniques and technologies for quantum information and communications, gravitational physics, nanophotonics, biology, etc.

This Special Issue of Photonics entitled “Exploring the Potential of Opto-Mechanics and Spin-Mechanics for Quantum Technologies” invites original works and short review articles considering any topic related to OM and SM that is a part of theoretical or experimental research. Submissions will be peer reviewed, according to the common procedure for publishing.

This paper presents the total angular momentum-conserving Poincaré sphere (TAM-C PS), which offers a novel framework for efficiently characterizing a wide range of vector vortex beams. Unlike other types of Poincaré spheres, the TAM-C PS achieves a better balance between generality and validity, while also providing clearer physical interpretation. By linking the poles of different spheres, the study also introduces two distinct categories of TAM-C PS braid clusters, enabling the representation of various Poincaré spheres within a unified framework. The Poincaré spheres include classical, higher-order, hybrid-order, Poincaré sphere with orbital angular momentum, and TAM-C PS. This is the first clear and unified approach to express multiple Poincaré spheres within a single framework. The TAM-C PS and its braid cluster can be employed to guide the creation of targeted vector vortex light beams, offer a geometric description of optical field evolution, and calculate the geometric phase of optical cyclic evolution.

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. Full article
