Query: Generating steady quantum coherence and magic through an autonomous
  thermodynamic machine by utilizing a spin bath   Generation of steady quantumness in the presence of an environment is of
utmost importance if we are to build practical quantum devices. We propose a
scheme of generating steady coherence and magic in a qubit system attached to a
heat bath at a certain temperature through its interaction with another qubit
system attached to a spin bath. Coherence generation in the reduced qubit is
always possible in this model. The steady coherence in the reduced qubit
attached to the heat bath may be used to enhance the subsequent transient
performance of a quantum absorption refrigerator. For the case of generation of
magic, which is the quantum resource responsible for implementation of gates
which are not simulable via stabilizer computation, we show that there exists a
critical temperature of the heat bath beyond which it is not possible to create
magic in the reduced qubit attached to the heat bath. Below the critical
temperature, the strength of interaction between the qubits must lie within a
certain region for creation of magic. We further note that by increasing the
strength of coupling of the second qubit to the spin bath, typified by the
reset probability, keeping the coupling strength of the first qubit to the heat
bath fixed, it is possible to increase the critical temperature of the heat
bath for creation of magic.
