Typical Entanglement of Superpositions
Damien Quinn, Joshuah T. Heath, Graham Kells
We investigate universal entanglement properties inherent to superpositions of randomized states. We find that an -fold superposition of typical states may be classified into tw…

Mapping the non-equilibrium interacting Anderson Impurity Model to an effective Gaussian theory
Emmanuel Bogacz, Graham Kells, Andrew K. Mitchell
Quantum impurity models with strong electron correlations, such as the paradigmatic Anderson Impurity Model (AIM), are central to our understanding of a range of physical phenomena…

Measurement Induced Dynamics and Trace Preserving Replica Cutoffs
Graham Kells
We present a general methodology for addressing the infinite hierarchy problem that arises in measurement-induced dynamics of replicated quantum systems. Our approach introduces tr…
