Theory

Our leading group is concerned with research in quantum information theory, condensed matter theory and the intersection between the fields.

- We ask what information processing tasks are possible using single quantum systems as carriers of information. We think about the mathematical-theoretical foundations of quantum information, specifically about the theory of entanglement and questions of tomography, but also about ways of realizing topological quantum computing.

Spin is among the frontrunners for the physical realization of quantum bits (qubits) and spin-based devices are at the center of an intense research effort for the creation of quantum protocols. The design of spin systems able to retain their quantum properties up to ambient temperature is one of the fields’ primary goals and represents a sine-qua-non condition for the realization of quantum devices based on magnetic units.

Progress in quantum technologies relies on understanding how quantum phenomena govern the dynamics of quantum systems far from equilibrium and on identifying the available quantum resources. This knowledge then allows us to manipulate the systems in order to obtain the desired outcome. Our group seeks to:

We are a theoretical group based in Koç University interested in quantum information theory and several aspects of quantum enabled and quantum enhanced technologies. Our group carries on theoretical research work on open quantum systems, quantum thermodynamics, quantum metrology, quantum computation.

Within the QI2-lab we primarily work on quantum metrology and sensing problems. We develop fundamental theory for quantum estimation tasks in order to focus on their optical implementations, with particular interest in atomic-ensemble and optomechanical quantum sensors. We also seek novel solutions in quantum information, cryptography and communication, especially exploring the device-independent framework.

We work on optimisation for and with the help of quantum computing. Examples: optimal compilation, variational algorithms, efficient embeddings.
