Quantification of Entanglement and Coherence with Purity Detection
Ting Zhang, Graeme Smith, John A. Smolin +7
Entanglement and coherence are fundamental properties of quantum systems, promising to power near future quantum technologies, such as quantum computation, quantum communication an…
On the separation of correlation-assisted sum capacities of multiple access channels
Akshay Seshadri, Felix Leditzky, Vikesh Siddhu +1
The capacity of a channel characterizes the maximum rate at which information can be transmitted through the channel asymptotically faithfully. For a channel with multiple senders…
The QAOA with Few Measurements
Anthony M. Polloreno, Graeme Smith
The Quantum Approximate Optimization Algorithm (QAOA) was originally developed to solve combinatorial optimization problems, but has become a standard for assessing the performance…
The platypus of the quantum channel zoo
Felix Leditzky, Debbie Leung, Vikesh Siddhu +2
Understanding quantum channels and the strange behavior of their capacities is a key objective of quantum information theory. Here we study a remarkably simple, low-dimensional, si…
Generic nonadditivity of quantum capacity in simple channels
Felix Leditzky, Debbie Leung, Vikesh Siddhu +2
Determining capacities of quantum channels is a fundamental question in quantum information theory. Despite having rigorous coding theorems quantifying the flow of information acro…
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…
