Boson Systems Shatter Quantum Speed Limits: Information Races Faster Than Particles

Information can travel faster than individual particles in systems made up of interacting bosons. Researchers at RIKEN have discovered that in certain quantum systems, information can propagate increasingly faster over time, challenging previous assumptions about universal speed limits such as those defined by the Lieb–Robinson bound. This analysis reveals fundamental differences in how bosons and [...]
