Optimal Linear-Rate Conversion of Unknown Mixed Qubit States via SWAP Tests
Sujay Kazi, Iman Marvian
By consuming multiple copies of an unknown qubit state, one can modify its purity while preserving the direction of its Bloch vector. We determine the maximum linear rate at which…
Thermal Quantum Sensing: Fisher Information and Work Beyond Gaussian Signals
Yash Chitgopekar, Nikolaos Koukoulekidis, Iman Marvian
Understanding how thermal fluctuations modify or suppress quantum-enhanced sensing is a central problem in quantum metrology. Closely related questions arise in quantum thermodynam…
Global Control with the Tavis-Cummings Interaction
Plato Deliyannis, Iman Marvian
We study the controllability of a system of qubits under global control, where control pulses act identically on all qubits. Specifically, we consider a collection of qubits identi…
Accidental Symmetry in the Tavis-Cummings Model via the Schwinger Boson Representation
Plato Deliyannis, Iman Marvian
The Jaynes-Cummings (JC) Hamiltonian is a paradigmatic model of light-matter interaction and, more generally, qubit-boson interactions, widely used across atomic, optical, and supe…
Symmetry and Asymmetry in Bosonic Gaussian Systems: A Resource-Theoretic Framework
Nikolaos Koukoulekidis, Iman Marvian
We study the interplay of symmetries and Gaussianity in bosonic systems, under closed and open dynamics, and develop a resource theory of Gaussian asymmetry. Specifically, we focus…
Optimal Distillation of Qubit Clocks
Sujay Kazi, Iman Marvian
We study coherence distillation under time-translation-invariant operations: given many copies of a quantum state containing coherence in the energy eigenbasis, the aim is to produ…
A resource theoretical unification of Mpemba effects: classical and quantum
Alessandro Summer, Mattia Moroder, Laetitia P. Bettmann +3
The Mpemba effect originally referred to the observation that, under certain thermalizing dynamics, initially hotter samples can cool faster than colder ones. This effect has since…
Optimal Distillation of Coherent States with Phase-Insensitive Operations
Shiv Akshar Yadavalli, Iman Marvian
By combining multiple copies of noisy coherent states of light (or other bosonic systems), it is possible to obtain a single mode in a state with lesser noise, a process known as d…
Observation of the Symmetry-Protected Signature of 3-body Interactions
Liudmila A. Zhukas, Qingfeng Wang, Or Katz +2
Identifying and characterizing multi-body interactions in quantum processes remains a significant challenge. This is partly because 2-body interactions can produce an arbitrary tim…
