Speed is a notion that formally sets bounds on the time that a quantum system takes to evolve. Here it is shown that speed is related to the notion of asymmetry, a result that provides direct connection with the problem of quantifying the coherence of quantum states.

• Quantum speed limits: from Heisenberg’s uncertainty principle to optimal quantum control (2017, background): “On the other hand, Mondal et al. [183], as well as Pires et al. [184], Marvian and Lidar [185], and Marvian et al. [186] focused on the loss of quantum coherence in isolated and open dynamics.”
• Quantum resource theories (2018, background): “The QRT of unspeakable coherence is essentially a resource theory of asymmetry for translations generated by any quantum observable (Marvian and Spekkens, 2014b, 2016; Marvian et al., 2016).”
• Quantum coherence and geometric quantum discord (2017, unknown): “For more detailed explanations about the relations between coherence and asymmetry, and a comparison of different notions of coherence, see the recent works of Marvian and Spekkens (2016) and Marvian et al. (2016).”
