Non-equilibrium quantum thermometry with bosonic samples
Marek Winczewski, MichaÅ Horodecki, Ricard Ravell RodrÃguez
We study low-temperature non-equilibrium quantum thermometry with a bosonic probe: a quantum harmonic oscillator strongly coupled to a bosonic bath at temperature through a Dru…

Quantification of the energy consumption of entanglement distribution
Karol Horodecki, Marek Winczewski, Leonard Sikorski +3
Inspired by environmental sciences, we develop a framework to quantify the energy needed to generate quantum entanglement via noisy quantum channels, focusing on the hardware-indep…

Corrections to the Hamiltonian induced by finite-strength coupling to the environment
Marcin Åobejko, Marek Winczewski, Gerardo Suárez +2
If a quantum system interacts with the environment, then the Hamiltonian acquires a correction known as the Lamb-shift term. There are two other corrections to the Hamiltonian, rel…
