Completed

1 [Optimal storage of quantum data] To determine the smallest amount of memory needed to store sequences of quantum data generated by an unknown physical process. To devise quantum protocols to learn quantum states in the presence of noise and change points. 2 [Optimal programmable processors] To identify the smallest quantum programs for execution of quantum gates within a desired level of accuracy. To design programmable quantum processors approaching the ultimate information-theoretic limit. 3 [Compressed simulations] To establish when and how the dynamics of a target system can be simulated on system of smaller size and to develop a general theory of compression for quantum processes.
