Steady-State Noise Signatures of Lindbladian Exceptional Points
Shihang Pan, Gianmichele Blasi, Géraldine Haack
Exceptional points (EPs) are non-Hermitian degeneracies at which two or more eigenvalues and their corresponding eigenvectors coalesce. In open quantum systems, exceptional points…
Thermodynamic Networks: Harnessing Non-Equilibrium Steady States for Computation
Patryk Lipka-Bartosik, Gianmichele Blasi, Javier Lalueza Puértolas +3
We introduce thermodynamic networks, a general framework for autonomous, physics-based computation using non-equilibrium steady states. These networks are modeled as a collection o…
Quantum Kinetic Uncertainty Relations in Mesoscopic Conductors at Strong Coupling
Gianmichele Blasi, Ricard Ravell RodrÃguez, Mykhailo Moskalets +2
Kinetic Uncertainty Relations (KURs) set fundamental limits on the precision of nonequilibrium transport by bounding the signal-to-noise ratio of currents in terms of the dynamical…
Exponential gain in clock precision using quantum correlated ticks
Florian Meier, Yuri Minoguchi, Gianmichele Blasi +2
Creating precise timing devices at ultra-short time scales is not just an important technological challenge, but confronts us with foundational questions about timekeeping's ultima…
Emergent Liouvillian exceptional points from exact principles
Shishir Khandelwal, Gianmichele Blasi
Recent years have seen a surge of interest in exceptional points in open quantum systems. The natural approach in this area has been the use of Markovian master equations. While th…
Transport approach to quantum state tomography
Jeanne Bourgeois, Gianmichele Blasi, Géraldine Haack
Quantum state tomography (QST) is a central task for quantum information processing, enabling quantum cryptography, computation, and state certification. Traditional QST relies on…
