Fundamental speed limits on quantum information dynamics
Abstract
propose a state-of-the-art investigation into the fundamental “speed limits” on the transfer of quantum information and the decoherence of many-body quantum states. What is the best way to design quantum hardware, which operates as fast as possible, with the highest possible fidelity? When are highly entangled many-body states, of use for metrology, provably robust against decoherence? Historically, such questions were addressed using techniques based off of the Lieb- Robinson theorem. However, this canonical tool is designed for lattice models, and is not relevant to many experimental platforms for quantum technology, particularly in atomic physics. These atomic platforms can have long range interactions, and/or bosonic degrees of freedom such as photons and phonons. My research group has already delivered cutting-edge mathematical frameworks which sharply constrain quantum information dynamics with power-law interactions.
