Symmetry-resolved parent Hamiltonians for entangled bosonic cat resources
Šimon Bräuer, Klaus Mølmer
Schrödinger cat states, formed from superpositions of well-separated coherent states, are promising resources for bosonic quantum information. We construct parent Hamiltonians for…
Generalization of catability for parity-less cat states
Michal Matulík, Jan Provazník, Petr Marek +1
We extend the nullifier-based certification framework of catability from parity-defined coherent cat states to parity-less Kerr cat states. Since Kerr cats cannot be distinguished…
Witnesses of non-Gaussian features as lower bounds of stellar rank
Jan Provazník, Šimon Bräuer, Vojtěch Kala +2
Quantum non-Gaussian states and operations serve as fundamental resources for universal quantum computation, error correction, and high-precision metrology, extending beyond the Ga…
Generalized squeezing as a witness
Šimon Bräuer, Tomáš Opatrný, Petr Marek
Quantum systems can be prepared in an infinite continuum of states, but only some of them can be used as resources for quantum technologies. Discerning whether a specific quantum s…
Nonlinear coherent heat machines and closed-system thermodynamics
Tomáš Opatrný, Šimon Bräuer, Abraham G. Kofman +5
All existing heat machines are dissipative open systems. Hence, they cannot operate fully coherently. We propose to replace this conventional thermodynamic paradigm by a completely…
