Physics Colloquium

Generating and characterizing correlations in noisy quantum systems

Archana Kamal
Assistant Professor
University of Massachusetts Lowell


Generating and manipulating quantum correlations are standard functionalities, prerequisite for performing any meaningful task in quantum information processing. These tasks are rendered particularly challenging in the presence of noise, which dominates the current multi-qubit platforms. This challenge is triggering new approaches such as quantum reservoir engineering that employs controlled dissipation to act on a quantum system, such that the resultant dynamics naturally relax the system to an entangled state (or state space) of interest. I will first describe how implementing a state-selective dissipation can lead to a new generation of reservoir engineering protocols, which realize deterministic entanglement generation with high fidelity and fast preparation rates. In the second part of the talk, I will outline the how characterizing correlations in noisy multi-mode systems can itself be non-trivial and our recent progress towards answering this question.
