Physical Review has indicated in a paper proof that they have their own style for author contribution statements. This style consists of massacring our statement, by repeating "formal analysis" multiple times & unnecessarily capitalizing phrases. Why does APS consistently have such poor copyediting?

here is what I see when I want to look up research papers on @nature.com 's web site. Why do I need to see ads like this? really??? Do you not get enough money from charging authors exorbitant publication fees? This is really pathetic.

Joint work with Kaiyuan Ji and Seth Lloyd now available at
arxiv.org/abs/2509.08965
This paper identifies the communication capacity for sending information from the future to the past through a noisy closed timelike curve. The formula is reminiscent of mutual info but in general can be larger.

Theshani Nuradha & I issued an important update of our paper on query complexity of q. channel discrimination:
arxiv.org/abs/2504.12989
Building on arxiv.org/abs/2506.13686, we gave a tight characterization of sample complexity of state discrimination & query complexity of cq channels. See images

We even invented a quantum Doeblin coefficient dedicated to our colleague Xin Wang @wangxinfelix.bsky.social, by using a technique from PhD thesis work (see attached image). The benefit of this technique is that the resulting quantity is multiplicative.
