Quantum Information & Computation

As part of CSTAR, we investigate the possibility of making use of quantum mechanics, the physics of fundamental particles, to build computing devices of the future. These machines, known as quantum computers are radically different from their classical counterparts. A major emphasis is given to the design of new algorithms that highlight the differences between classical and quantum computation in the different models of quantum computation. In the near term, we intend to develop algorithms with practical applications for quantum computers that will be available soon.

Furthermore, we work on the problem of communicating between several parties using quantum resources. Quantum communication offers the possibility of developing protocols that are more far more efficient and secure than their classical counterpart. We also look to advance the foundational aspects of quantum mechanics, which help understand the nature of reality and form the bedrock of any quantum technological application.

In reality, quantum systems are never isolated and invariably interact with an external environment. Another direction of research pursued by our group is to explore the dynamics of quantum systems in the presence of noise. In particular, we intend to model devices such as quantum diodes and transistors which are essential ingredients to develop a quantum electronic circuit theory.

Our group is also part of the Centre for Quantum Science and Technology at IIIT Hyderabad.
