Connecting Quantum Tomography and Quantum Retrodiction
Sebastian Murk, Ian Tan, Fabian Müller +1
Quantum tomography and quantum retrodiction are traditionally viewed as separate inference tasks: tomography reconstructs quantum states from measurement data, whereas retrodiction…

Rotational Quantum Tunneling of a Magnetic Dipole in a Superconducting Trap
Francis J. Headley, Fabian Müller, Emre Köse +3
We study the quantum dynamics of the rotational degree of freedom of a nano-magnet trapped in a superconducting trap. The nano-magnet is modeled as a magnetic dipole with magnetiza…

Lellouch-Lüscher factor for the decays
Jin-Yi Pang, Rishabh Bubna, Fabian Müller +2
We derive an explicit expression for the Lellouch-Lüscher (LL) factor in the decays at leading order (without derivative couplings). Several important technical details…
