Coherence distillation machines are impossible in quantum thermodynamics

Can an idealised machine obtain pure coherent quantum states from mixed ones at a non-zero rate, or equivalently, can a machine distill synchronized quantum clocks starting from noisy ones? Iman Marvian demonstrates that this is impossible, even if the machine is allowed to spend an arbitrary amount...
