•We use Concurrence to meaure the entanglement of two qubits in new graphene-based quantum chip in a thermal reservoir.•The entanglements of two qubits' initial Bell basis and Werner state are kept in several seconds and then decrease to zero.•The second-long entanglment time provides a guarantee for quantum computing in new quantum chip. We study the entanglement of two interacting electric dipolar molecules in graphene in a thermal reservoir measured by Wootters’ Concurrence. The entanglements of the two qubits’ initial Bell basis and Werner state are both kept in several seconds and then decrease to zero.
