The quantum speed limit indicates the maximal evolution speed of the quantum system. In
this work, we determine speed limits on the informational measures, namely the von …

The quantum speed limit is important in determining the minimum evolution time of a
quantum system, and thus is essential for quantum community. In this Letter, we derive a …

In the Schrödinger picture, the state of a quantum system evolves in time and the quantum
speed limit describes how fast the state of a quantum system evolves from an initial state to a …

Quantum speed limit is bound on the minimum time a quantum system requires to evolve
from an initial state to final state under a given dynamical process. It sheds light on how fast …

The quantum speed limit describes how quickly a quantum system can evolve in time from
an initial state to a final state under a given dynamics. Here, we derive a generalised …

How fast an observable can evolve in time is answered by so-called observable speed limit.
Here, we prove a stronger version of the observable speed limit and show that the …

Quantum absorption refrigerator (QAR) autonomously extracts heat from a cold bath and
dumps into a hot bath by exploiting the input heat from a higher temperature reservoir. QARs …

Measurement-based quantum thermal machines are fascinating models of thermodynamic
cycles where measurement protocols play an important role in the performance and …

We explore a small quantum refrigerator in which the working substance is made of
paradigmatic nearest-neighbor quantum spin models, the XYZ and the XY model with …

Multiterminal multidot devices have been put forward as versatile and high-performing
setups for thermoelectric energy harvesting at the nanoscale. With a technique that …
