Theoretical experiment posed by John Preskill to reason through the paradox of quantum cloning (observing information in two different places, one by scrambled Hawking Radiation, and the other through a direct message sent by A)

Within the framework of the information paradox, one line of inquiry brings us to the effects on information of maximally entangled systems. Having firm control over the fundamentals of formalism and conventions of quantum mechanics, consider the density matrices of various n-dimensional systems of quantum information as they undergo random unitary transformations. Establishing an understanding of quantum information within the realm of black holes. Looking at the rapid thermalization of black holes, quantum information could be revealed near-instantly in the form of Hawking radiation. Rapid thermalization, or fast scrambling, can be described by quantum information theory, so we describe randomization of information using unitary transformations on entangled subsystems so as to explain how the latter half the entropic life-span allows for a set amount of information to be instantly retrievable.

ALCF Data Warehouse Usage Visualization in Java
A low-level data visualization tool that serves as a kick-start to a much larger visualization program for use in data architecture in Argonne's Leadership Computing Facility (ALCF). This flexible, lightweight, and customizable visualization tool works with Java to view and interact with large data sets. The main focus of this project was the visualization of usage of machines over the course of a month's worth of data.
Focusing on the two top windows, and ignoring the yellow one on the left: The blue bars at the top of the page represent the downtime in the computers, scheduled maintenance is often the cause. The middle section with blue, pink, and green represent the types of machines being used at any given moment. The bottom section in the orange and gold represent the standard queue time for each job being pushed to the machines--orange represents waiting, gold represents priority.
