Detecting Initial System-Environment Correlations from a Single Observable
Ali Abu-Nada, Russell Ceballos, Lian-Ao Wu
We address the problem of detecting initial system--environment correlations when the environment is not directly accessible. Most existing approaches rely on full state tomography…

Hybrid Predictive Quantum Feedback: Extending Qubit Lifetimes Beyond the Wiseman-Milburn Limit
Ali Abu-Nada, Aryan Iliat, Russell Ceballos
Amplitude damping fundamentally limits qubit lifetimes by irreversibly leaking energy and information into the environment. Standard Wiseman--Milburn feedback offers only modest im…
