FRG 3 - Quantum Information Processing
Focus Research Group 3 will utilize Bose-Einstein condensates for the implementation of quantum emulation and quantum computation, which have applications in fundamental problems of strongly correlated, many-body physics and can potentially allow quantum computation above the ultra-low temperature regime that limits current platforms.

Research Thrust 1:
Bose Einstein condensates (BECs) are ideal platforms for working out the consequences of a wide variety of ideal quantum Hamiltonians. This kind of quantum emulation uses the BEC to simulate phases or physics relevant to other more complicated systems that cannot be calculated easily with digital computers. BECs are powerful tools for quantum emulation because they form effectively zero-temperature quantum materials with perfect coherence. These complex quantum systems will be explored experimentally in ultracold atoms and in exciton-polaritons, as well as explored theoretically.
Research Thrust 2:
Quantum computers are known to outperform classical computers at a variety of tasks, including breaking public-key cryptographic systems, searching databases, and finding approximate solutions to optimization problems. Governments across the world have recognized quantum computing's potential for ushering a technological revolution by passing strategic legislation funding for its research and development. In the U.S., the National Quantum Initiative Act was passed by Congress in December 2018 and quickly signed into law. In this thrust, FRG 3 proposes to investigate quantum algorithms based on quantum walks and a new qubit based on crosswire quantum dots.
