Abstract

We show that the \((1+3)\)-dimensional ‘superboost’ operators, proposed in Dragan and Ekert’s most recent work on superluminal reference frames (Dragan et al. in Class Quantum Gravity 40(2): 025013, 2023), are simply the canonical Lorentz boosts, expressed in nonstandard notation. Their \((1+3)\)-dimensional ‘superflip’, which is claimed to interchange time and space dimensions for a superluminal observer, travelling with infinite speed, is equivalent to applying the identity operator together with an arbitrary relabeling. Physically, it corresponds to staying put within the canonical rest frame, then renaming space as ‘time’ and time as ‘space’. We conclude that their extension of the ‘quantum principle of relativity’, proposed in earlier work on \((1+1)\)-dimensional spacetimes (Dragan and Ekert in New J Phys 22(3): 033038, 2020), to ordinary Minkowski space, is simply Einstein’s principle of relativity, proposed in 1905.

\((1+3)\)维的“量子相对性原理”是爱因斯坦的相对性原理

我们表明，在Dragan和Ekert最近关于超光速参考系的工作中提出的\((1+3)\) -维“超级推进”算子（Dragan等人在量子引力类40(2):025013,2023中），只是用非标准符号表示的规范洛伦兹推进。他们的\((1+3)\)维“超级翻转”（superflip），声称可以为一个以无限速度旅行的超光速观察者交换时间和空间维度，相当于将恒等算子与任意重新标记一起应用。从物理上讲，它对应于保持在规范的静止框架内，然后将空间重命名为“时间”，将时间重命名为“空间”。我们得出的结论是，他们将先前在\((1+1)\)维时空的研究中提出的“量子相对性原理”（Dragan和Ekert在《新J物理学》22(3):033038,2020）扩展到普通的闵可夫斯基空间，就是爱因斯坦在1905年提出的相对性原理。
