Local Certification of Many-Body Steady States
Miguel Frías Pérez, Antonio Acín
We present a relaxation-based method to bound expectation values on the steady state of dissipative many-body quantum systems described by master equations of the Lindblad form. In…
Certification of quantum properties with imperfect measurements
Leonardo Zambrano, Teodor Parella-Dilmé, Antonio Acín +1
The accurate characterization of quantum systems is essential for the advancement of quantum technologies. In particular, certifying convex functions of quantum states plays a cent…
Bounding many-body properties under partial information and finite measurement statistics
Luke Mortimer, Leonardo Zambrano, Antonio Acín +1
Calculating bounds of properties of many-body quantum systems is of paramount importance, since they guide our understanding of emergent quantum phenomena and complement the insigh…
Certified bounds on optimization problems in quantum theory
Younes Naceur, Jie Wang, Victor Magron +1
Semidefinite relaxations of polynomial optimization have become a central tool for addressing the non-convex optimization problems over non-commutative operators that are ubiquitou…
Exclusive Control of Quantum Memory Erasure
Mir Alimuddin, Nathan Shettell, Raja Yehia +2
Erasing memory is a fundamental operational task in quantum information processing, governed by Landauer's principle, which links information loss to thermodynamic work. We introdu…
Hamiltonian learning via quantum Zeno effect
Giacomo Franceschetto, Egle Pagliaro, Luciano Pereira +2
Determining the Hamiltonian of a quantum system is essential for understanding its dynamics and validating its behavior. Hamiltonian learning provides a data-driven approach to rec…
