Query: Clock-Driven Quantum Thermal Engines   We consider an isolated autonomous quantum machine, where an explicit quantum
clock is responsible for performing all transformations on an arbitrary quantum
system (the engine), via a time-independent Hamiltonian. In a general context,
we show that this model can exactly implement any energy-conserving unitary on
the engine, without degrading the clock. Furthermore, we show that when the
engine includes a quantum work storage device we can approximately perform
completely general unitaries on the remainder of the engine. This framework can
be used in quantum thermodynamics to carry out arbitrary transformations of a
system, with accuracy and extracted work as close to optimal as desired, whilst
obeying the first and second laws of thermodynamics. We thus show that
autonomous thermal machines suffer no intrinsic thermodynamic cost compared to
externally controlled ones.
