We study the entanglement dynamics of two electrons in a dissipative quantum walk on a cycle graph. The considered dissipation, which is inevitably induced by coupling to a measurement apparatus, can make the quantum system unreliable by breaking entanglement between two electrons. However, for certain realistic parameters a distinct maximum of fermionic entanglement can be established and entanglement revival can be observed.
