Bright Quantum Squeezed Light in IIST

Bright Quantum Squeezed Light in IIST Quantum squeezing refers to quantum noise reduction beyond the standard quantum limit (SQL), the minimum noise limit in classical physics. In IIST, for the first time in India, we have generated the bright-entangled twin beams of light and measured their intensity-difference squeezing of 4 dB, corresponding to a 60% noise reduction from the SQL. The squeezed light is an important resource for quantum communication and quantum cryptography, quantum enhanced sensing and quantum information processing.

Common inlet system for aerosol sampling

A common aerosol sampling inlet system (ASIS) is designed and developed at IIST to sample the ambient aerosols to characterize their physical, optical, and chemical properties (Figure 7). The developed inlet system can provide humidity-controlled aerosol flow at rates up to 38.4 liter/minute at a particle size-cut of 10 µm. The custom-designed diffusion dryer in the ASIS effectively reduces relative humidity (RH) by 34-40% on an average at a flow rate of 10 liter/minute, even under extreme RH conditions (RH>90%).

Microgravity Simulating Platform

Random positioning machine (RPM) as a ground based microgravity simulating platform was designed, fabricated and validated. Experiments using biological samples proved that the achieved microgravity levels (10-3g) significantly influenced many biological parameters and the results were also compared with data from spaceflight studies. The developed RPM can be effectively utilized for the ground based optimization of spaceflight experiments. (currently under patent filing: KG Sreejalekshmi and Srujana Juratagi)

INSPIRESat-1: The Student Satellite

InspireSat-1 was successfully launched on board the PSLV C52 mission on February 14, 2022 and is being successfully operated by the students of IIST from the IIST ground station with support from the INSPIRE partners including LASP, USA and NCU, Taiwan, and NTU, Singapore.

Qawwali by Warsi Brothers @ IIST

IIST and SPIC MACAY jointly hosted a mesmerizing Qawwali Programme by Warsi Brothers in IIST campus on 6th November 2024, offering students, faculty, and guests an evening of transcendent music, soulful poetry, and spiritual reflection. The event was a beautiful blend of cultural tradition and spiritual devotion, aiming to deepen the connection between the mind, body, and spirit through the mystical art of Sufi music.

IIST Annual Sports Meet

The annual sports meet for the academic year 2024-25 was conducted on 31 January 2025. The students participated in various sports events under the flags of five houses, namely; Akashganga, Devyani, Kritika, Saptarshi and Sharmista. The sports meet was inaugurated at 9.30 AM by the chief guest Mr. Shahansha M S IPS, Commandant Special Armed Police. Prof. Kuruvilla Joseph (Registrar and Dean-Academics) welcomed the gathering. Prof.Dipankar Banerjee,Director,IIST delivered the presidential address.The Chief Guest received the salute from the march-pasts of various house teams.

Inauguration of Art Gallery and Space Museum

The Art Gallery and Space Museum in the Interdisciplinary Block was inaugurated on 11th February 2025, by Prof. Dipankar Banerjee (Director,IIST), facilitated by Prof Kuruvilla Joseph (Registrar, IIST), the CMD, and the Humanities and Social Sciences Department . In the Space musuem there are 23 miniature space craft exhibits ranging from Aryabhata to Crew Module. The art gallery specializes in upcycled scrap installations and also paintings by famous artists like Shri. Marthandom Shri. Rajashelharan and Shri. Kannan Chitralaya.

Smart Classroom in Government school Technology-enhanced learning

A team from IIST participated in the 43rd annual meeting of the Astronomical Society of India (ASI), held between 16-19 Feb 2025 at NIT-Rourkela. The team included Prof. Dipankar Banerjee, Director, IIST, who was the President of ASI, Prof. Sarita Vig, who is the Secretary of ASI, Prof. Umesh Kadhane – invited Plenary speaker and a number of PhD, Masters and undergraduate students. Prof Dipankar Banerjee delivered the Presidential address. Prof. Sarita Vig carried out the proceedings of the Inaugural and Concluding sessions as well as chaired the session on ASI Awards talks.

PILOT

Pslv-In-orbitaL Obc and Thermals (PILOT), is a payload designed for the fourth (and final) stage of PSLV with the aim to achieve thermal model validation and flight qualifications for the in-house developed On-board computer, which is expected to fly in multiple upcoming missions developed at SSPACE. The payload carries a number of temperature sensors which are used to collect valuable thermal data for thermal model validation of various subsystems in LEO. The PILOT payload has a volume of ~1U, and a mass of less than 1kg. The bus is designed to work on less than 0.5W power.
