Detecting entanglement with a thermometer
Janet Anders, Dagomir Kaszlikowski, Christian Lunkes +2
We present a general argument showing that the temperature as well as other thermodynamical state variables can qualify as entanglement witnesses for spatial entanglement. This hol…
Increasing identical particle entanglement by fuzzy measurements
D. Cavalcanti, M. F. Santos, M. O. Terra Cunha +2
We investigate the effects of fuzzy measurements on spin entanglement for identical particles, both fermions and bosons. We first consider an ideal measurement apparatus and define…
Natural multiparticle entanglement in a Fermi gas
C. Lunkes, C. Brukner, V. Vedral
We investigate multipartite entanglement in a non-interacting fermion gas, as a function of fermion separation, starting from the many particle fermion density matrix. We prove tha…
Equation of state for Entanglement in a Fermi gas
Christian Lunkes, Caslav Brukner, Vlatko Vedral
Entanglement distance is the maximal separation between two entangled electrons in a degenerate electron gas. Beyond that distance, all entanglement disappears. We relate entanglem…
