An information-theoretic proof of the Planckian bound for thermalization
Quantum mechanics provides a minimum time for the thermalization of any system. Here we prove this mathematically.
Optimal Cycles for Low-Dissipation Heat Engines
We solve the optimal control for (thermal) machines operating in the high-efficiency regime.
Collective Advantages in Finite-Time Thermodynamics
A clever design of inter-particle interaction can dramatically reduce dissipation.
Single-photon nonlocality in quantum networks
A single-photon can be non-locally in two separate regions of space, but this is impossible to certify via photodetection alone. Here we show that the nonlocality of 3 single-photons in a triangle network can instead be witnessed with photodetectors-clicks.
Physicality of evolution and statistical contractivity as equivalent notions of maps
Physical evolutions can only decrease relative distinguishability between physical states, i.e. they are contractions. Here we show the opposite: contractive maps are necessarily physical.
Fundamental Limits of Metrology at Thermal Equilibrium
Finding the optimal control and ultimate parameter estimation precision for probes at thermal equilibrium, with surprising Quantum scaling.
Optimal quantum metrology when you have unentangled probes and time-independent control.
Optimal thermometers with spin networks
It turns out that the mathematical limit of an ideal thermometer can be realized with simple interactions design.
