Quantum Algorithms
What practical problems can quantum computers solve with a provable advantage over classical methods? And how much of this potential can already be realized on today’s devices, which have only a few qubits, shallow circuit depth, and limited ancilla? Our research in quantum algorithms is motivated by these questions. We design algorithms for both fully fault-tolerant quantum computers and near/intermediate...

Quantum Cryptography and Foundations
Prior to Mahadev’s 2018 breakthroughs, the term quantum cryptography was dominated by advances in quantum key distribution—that we already explained. Today, the field has blossomed into a diverse and rich sub-discipline with increasingly intricate underlying mathematics. We briefly describe ...

Quantum Information, Thermal and Open Quantum Systems
Quantum information, like we briefly described on the expertise page, is closely related to various concepts—such as the fundamental limitations of communication over quantum channels and the notion of security of cryptographic protocols...

Quantum Networks
Quantum networks form the key component of both distributed quantum computing and quantum communication as it helps us to transfer quantum as well as classical information. Last couple of years we have seen significant advancement of quantum technology. We are able to establish different quantum networks either by free-space...
