Current Research

We believe in a multi-faceted approach to research. Furthermore, we believe it is essential to develop a strong research base in theoretical quantum computing so that we are prepared to meet the challenges of large quantum volume when it becomes available. Our current areas of research are listed below

MBQC

Measurement-based quantum computing is an alternative framework to the more popular gate-based quantum computing (GBQC). There are several novel features to this approach including the possibility of blind quantum computation which is a very important area considering that in the near future, access to quantum computers will be based on a client-server model and it is paramount to ensure security and secrecy of computation. We are exploring avenues like the equivalence of MBQC and GBQC and simulations of MBQC using IBM Q experience devices

Polynomials

We have explored that gate circuits on IBM Q devices have a polynomial structure. We are pursuing the possible implications of this for quantum circuit optimization and qubit routing. We are focused on developing a theoretical framework for the analysis and interconversion of circuit polynomials and their applications to algorithms etc

Errors

NISQ devices are limited in capability and circuit size by gate and qubit errors. While improved devices are being developed, it is important to be able to optimize circuits in an architecture-agnostic manner since in the near future we will have access to quantum computers developed by various manufacturers using different technologies (photonic qubits, spin qubits etc.). We’re studying ways to generalize error causing factors for quantum devices and creating optimization methods and frameworks that can adapt to the error profiles of different devices.

Quantum Key Distribution

With the increasing popularity of quantum computing and the pressing threat of post-quantum cryptography in the NISQ era, it is of great importance to be able to set up a quantum internet so that qubits can be shared over large distances. Protocols need to be designed and analyzed for the same. This is also a requirement for blind quantum computation.

Hybrid quantum computing

Quantum computing improves over classical computers in the simulation of quantum mechanical systems. With access to limited hardware, it is very important to develop and optimize algorithms so that we can get the most quantum performance out of the available hardware and using them to augment classical computers for simulation of quantum systems. We hope to carry out quantum chemistry simulations and develop methods to optimize existing algorithms for NISQ hardware.

Quantum Technologies and Quantum Machine Learning

We are also looking to explore the application of quantum computing that are on the forefront of modern research including in-depth investigations into the capabilities of quantum technologies and the engineering design of such devices. We are also looking into upcoming fields like quantum machine learning and applications of extensions of algorithms that exist while also developing new novel algorithms


Other notable activities

Summer Training

In line with our goal of increasing interest and developing manpower for quantum computation, QuLabs@IITR organized a summer training program for first-year undergraduate students. This course is one of the first of its kind to run in an educational institution in India with the participants being chosen from a pool of applicants from within the institute.
The course comprised of intensive lectures introducing students to the basics of linear algebra, quantum mechanics and topics in quantum computation including entanglement, multi-qubit computation, quantum key distribution and quantum algorithms. All topics were accompanied by hands-on sessions of implementation on IBM Q machines using Qiskit.
It was a very intensive short course, spanning just over two weeks, 2-hour long sessions twice a day. The students were also given problem sets, solutions to which they were required to submit in typed format. As a result, we have developed course materials which we plan to use in the course targeted at a larger audience. The problem bank will also be used for the same. The students have expressed further interest to continue learning about quantum computing and might pursue further research in the area.
Lectures were taken by Prof. Gangopadhyay and Prof. Poonia as well as Jothishwaran and Abhishek. Jothishwaran, Abhishek and Dr Tajender are currently involved in refining the course content developed during the program. We hope to run similar programs for a larger number of students from within the institute as well as outside in upcoming years.

It contains the following points:


● Development of an indigenous high-performance quantum simulator
● Developing a toolkit for the rapid development of quantum computing applications
● Collaboration with CDAC to create a course on quantum computing so that we can create awareness and develop manpower for quantum computing.
