Quantum thermometry by single-qubit dephasing
Sholeh Razavian, Claudia Benedetti, Matteo Bina +2
We address the dephasing dynamics of a qubit as an effective process to estimate the temperature of its environment. Our scheme is inherently quantum, since it exploits the sensiti…

Entanglement witnesses for families of the bound entangled three-qubit states
Yahya Akbari-Kourbolagh
We construct three-qubit entanglement witnesses with relatively simple structures. Despite their simplicity, these witnesses are capable of detecting a number of bound entangled st…
