We celebrate the 10-year anniversary of the Quantum Optics and Entanglement Lab. Our deepest gratitude extends to each member, past and present, whose contributions have shaped our journey. For a decade, our lab has passionately delved into the realms of coherence and quantum entanglement, focusing on Orbital Angular Momentum (OAM), spatial, and radial degrees of freedom. We are committed to making meaningful contributions to quantum metrology, information, communication, and imaging.

Suman and Radhika presented their research at the FIO conference. Suman presented a poster highlighting his recent work titled : Broadband uniform-efficiency OAM detector , while Radhika delivered a talk on her recent work titled : Structuring two-photon correlation of entangled field: experimental demonstration . Congratulations to both of them.

Suman was selected for the prestigious FiO+LS Incubic Milton Chang Travel Grant, enabling him to attend the FIO 2023 conference and present his work. Many congratulations to Suman.

Suman recieved the Best Poster Award at the international conference Photonics 2023 held at IISC Bangalore, India, during 5-8 July 2023. In the poster, he presented his recent work on Broadband uniform-efficiency OAM detector. Many congratulations to Suman and the co-authors for their contribution.

Prof. Siddharth Ramachandran from Boston University visited the Quantum Optics and Entanglement Lab. Prof. Ramachandran is a distinguished faculty in the department of Engineering (ECE, Physics, MSE) and will be associated with IIT kanpur as a visiting faculty for the next two years.

Heartfelt congratulations to Pranay for being awarded, prime-minister's research fellowship (PMRF), the most prestigious doctoral fellowship in India. Prany's doctoral research is focussed on spatial two photon coherence and entanglement and its applications in quantum imaging, sensing, and metrology.

HHeartfelt congratulations to Pranay for being awarded, prime-minister's research fellowship (PMRF), the most prestigious doctoral fellowship in India. Nilakshi's doctoral research is focussed on multiphoton high-dimensioanl entanglement. Nilakshi plans to explore the orbital angular momentum of light and exploit if for quantum information applications.

Prof. Miguel Alonso from Aix Marseille Université, France, and the University of Rochester, Rochester, USA, visited the Quantum Optics and Entanglement Lab at IIT Kanpur. He is joining IIT Kanpur as a visiting faculty for a period of one year under VAJRA scheme of the SERB, department of science and technology. We look forward to a fruitful collaboration and academic exchange.

Suman presented his latest research at the ICOAM 2022 conference, held at Tampere University in Finland during 12-17 June, 2022. Suman presented a poster on his recent work with the title : Controlled generation of high-dimensional OAM entangled state without postselection . Many congratulations to Suman.

Suman was awarded the esteemed OPTICA travel grant to attend the ICOAM 2022 conference. Many congratulations to Suman.
