Uniform Additivity of Tripartite Optimized Correlation Measures
Joshua Levin, Ariel Shlosberg, Vikesh Siddhu +1
Information theory provides a framework for answering fundamental questions about the optimal performance of many important quantum communication and computational tasks. In many c…
The horocycle regulator: exact cutoff-independence in AdS/CFT
Sristy Agrawal, Oliver DeWolfe, Kenneth Higginbotham +1
While the entanglement entropy of a single subregion in quantum field theory is formally infinite and requires regularization, certain combinations of entropies are perfectly finit…
Opportunities and Limitations in Broadband Sensing
Anthony M. Polloreno, Jacob L. Beckey, Joshua Levin +5
We consider estimating the magnitude of a monochromatic AC signal that couples to a two-level sensor. For any detection protocol, the precision achieved depends on the signal's fre…
Phase Transitions of Correlations in Black Hole Geometries
Sristy Agrawal, Oliver DeWolfe, Joshua Levin +1
We study the holographic realization of optimized correlation measures -- measures of quantum correlation that generalize elementary entropic formulas -- in two-dimensional thermal…
Multipartite Optimized Correlation Measures and Holography
Oliver DeWolfe, Joshua Levin, Graeme Smith
We explore ways to quantify multipartite correlations, in quantum information and in holography. We focus on optimized correlation measures, linear combinations of entropies minimi…
Correlation measures and distillable entanglement in AdS/CFT
Joshua Levin, Oliver DeWolfe, Graeme Smith
Recent developments have exposed close connections between quantum information and holography. In this paper, we explore the geometrical interpretations of the recently introduced…
Playing Games with Multiple Access Channels
Felix Leditzky, Mohammad A. Alhejji, Joshua Levin +1
Communication networks have multiple users, each sending and receiving messages. A multiple access channel (MAC) models multiple senders transmitting to a single receiver, such as…
Optimized Measures of Bipartite Quantum Correlation
Joshua Levin, Graeme Smith
How can we characterize different types of correlation between quantum systems? Since correlations cannot be generated locally, we take any real function of a multipartite state wh…
