An Algorithm for Estimating -Stabilizer Rényi Entropies via Purity
Benjamin Stratton
Non-stabilizerness, or magic, is a resource for universal quantum computation in most fault-tolerant architectures; access to states with non-stabilizerness allows for non-classica…

Cooling a Qubit using n Others
Jake Xuereb, Benjamin Stratton, Alberto Rolandi +3
In the task of unitarily cooling a quantum system with access to a larger quantum system, known as the machine or reservoir, how does the structure of the machine impact an agent's…

Informational non-equilibrium concentration
Chung-Yun Hsieh, Benjamin Stratton, Hao-Cheng Weng +1
Informational contributions to thermodynamics can be studied in isolation by considering systems with fully-degenerate Hamiltonians. In this regime, being in non-equilibrium -- ter…
