Heralded generation of maximal entanglement in any dimension via incoherent coupling to thermal baths

Heralded generation of maximal entanglement in any dimension via incoherent coupling to thermal baths

We present a scheme for dissipatively generating maximal entanglement in a heralded manner. Our setup requires incoherent interactions with two thermal baths at different temperatures, but no source of work or control. A pair of $(d+1)$-dimensional quantum systems is first driven to an entangled ste...
