| Abstract | Quantum state preparation is an essential ingredient in quantum information processing. In this letter, based on quantum coherent control induced by Bell measurement, non-Gaussian operations, namely adding (subtracting) one single photon to (from) Gaussian-like input signal field, has been implemented to generate a single-photon-added and -subtracted coherent (SPASC) superposition state. In order to carry out the coherent control, a specified conceptual experiment apparatus has been proposed. By adjusting beamsplitter reflectivity and parameter gain of χ(2) nonlinear crystal, the ingredients of this superposition state can be manipulated. With the help of quasi-probability distribution Wigner function, the evolution of non-classical properties with two controllable parameters can be visualized for this superposition state. The results show a quantum non-Gaussian superposition state can be generated by the measurement-induced coherent control scheme. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
