Anderson Orthogonality as Measurement Backaction in Coupled Quantum Dots
Will Grant, Sarath Sankar, Elena Cornick +9
Measurement perturbs a quantum system by coupling it to external degrees of freedom, but detector backaction depends on the physical mechanism of measurement itself. In solid-state…
Boundary quenches in (1+1)-dimensional conformal field theory
Michele Fossati, Colin Rylands, Eytan Grosfeld +2
We investigate a class of local quantum quenches in which the conformal boundary condition of a (1+1)-dimensional conformal field theory is abruptly changed. We derive a remarkably…
Entropy of Non-Abelian Anyons from Slow Quasiparticle Dynamics in Quantum Hall Interferometers
Eran Sela, Mitali Banerjee
Non-Abelian anyons emerging in fractional quantum Hall states carry a characteristic entropy, , where is the anyon's quantum dimension. This …
Remote entropy measurement in coupled quantum dots
Owen Sheekey, Tim Child, Elena Cornick +8
Recent experiments have demonstrated that measurements of the entropy change associated with the addition of electrons to semiconductor- and graphene-based quantum dots accurately…
Arrow of Time as an indicator of Measurement-Induced Phase Transitions
Nitay Hurvitz, Alon Kochol, Victor Fleurov +1
Measurement-induced phase transitions (MIPTs) in monitored quantum systems are typically diagnosed using entanglement-based measures. Here, we develop a complementary thermodynamic…
Roadmap on Quantum Thermodynamics
Steve Campbell, Irene D'Amico, Mario A. Ciampini +66
The last two decades has seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicabilit…
