In 2022, quantum computing has gotten off to an excellent start. India has significant capabilities in quantum technologies. Let's look at the best universities in India with quantum computing research.

In September 2018, PitchBook released a report that said investors had put $1.02 billion into quantum computing companies until September 2021. The World Economic Forum just put out the first guidelines for Quantum Computing. In addition, universities worldwide are investing money into research to help move this technology forward. Let's look at a few of the best places for research in quantum computing. 

Indian Institute of Science – Initiative on Quantum Technologies (IQT@IISc)

IISc launched its Quantum Technology Initiative (IQTI) in September 2020 to establish a solid foundation for the field of quantum technologies and create a framework to encourage collaborations between physicists, material scientists, computer scientists, and engineers. In addition, national and international associations would use the Institute's research expertise in quantum technologies while establishing an innovative research and development platform. This program is more than just academic research; it will actively collaborate with businesses and other strategic partners to develop technology that will have both positive economic and social effects.

Indian Institute of Technology Jodhpur

IIT Jodhpur's Quantum Information and Computation (QIC) group investigates classical and quantum correlations. Such correlations play a critical role in the quest to comprehend and harness the power of quantum mechanics and the fundamentals of quantum information processing. We are addressing some essential issues of characterizing multiqubit entanglement as a group. Quantum key distribution, quantum dense coding, quantum teleportation, quantum cryptography, quantum game theory, and secure quantum communication are the applications covered by the spectrum. When implementing any quantum information task, it is critical to consider the role of noise in the chosen task. The group is interested in using Open Quantum Systems ideas and techniques to systematically study quantum information and computation in realistic scenarios, including the effect of ambient noise.

Indian Institute of Technology Madras 

The Center for Quantum Information, Communication, and Computing at IITM. The centre works on various quantum technologies, including communication, sensing, measuring, and computing. The Center was to find new ways to use quantum technologies in secure quantum communications. This centre includes quantum essential delivery, quantum random number generation, quantum sensing and metrology, and quantum computing innovations.

Tata Institute of Fundamental Research (TIFR) – Quantum Measurement and Control Laboratory

TIFR's Quantum Measurement and Control Laboratory (QuMaC) focuses on quantum phenomena in superconducting circuits. These nanofabricated electrical circuits are programmed to act like "artificial atoms" with quantized energy levels. We can combine two of these levels to form a quantum bit (qubit), which We can use to store and process data. With such qubits, We can build powerful computing machines capable of providing exponential speedup for some mathematical issues. Their lab aims to address the fundamental challenges of building and controlling such quantum systems. 

Indian Institute of Science Education and Research (IISER) Pune

The Department of Science and Technology (DST) and IISER Pune have established a Quantum Technology Innovation Hub. The technology hub, known as the I-Hub Quantum Technology Foundation (I-Hub QTF), has now been selected as a Section-8 company at IISER Pune. The I-Hub QTF will work to create quantum computers, quantum communication devices and systems, novel quantum materials, and quantum sensors for everyday use.

Quantum Information and Computing (QuIC) lab at the Raman Research Institute, Bangalore

The Quantum Information and Computing (QuIC) lab at the Raman Research Institute in Bangalore was one of the first in India to manufacture and use heralded and entangled photon sources for various quantum technology applications. Prof Urbasi Sinha established the Quantum Information and Computing Lab, which employs several scientists. The team's significant bang results in quantum communications have wowed the research community and the popular media.

Harish-Chandra Research Institute (HRI) – Quantum Information and Computation Group

At the Harish-Chandra Research Institute (HRI), Prayagraj (Allahabad), the Quantum Information and Computation (QIC) Group conducts research on a variety of quantum information and computation-related topics. This centre covers entanglement theory, quantum algorithms, quantum communication, and quantum cryptography. The QIC group is also actively involved in the recently emerging field at the intersection of quantum information and quantum many-body physics. Other areas of interest include quantum optical systems and realizable quantum computers in extremely cold gasses. They also work on related topics such as the theoretical underpinnings of quantum mechanics, geometric phases, and quantum information processing in the presence of closed time-like curves.
