Quantum Memory Burden Effect 

We review a phenomenon called the „memory burden effect“ and its implications for various systems ranging from  black holes, both primordial and astrophysical,  all the way to quantum systems in table top labs.  The phenomenon is universal in the systems of efficient quantum information storage and its essence is that the information load tends to stabilize the „host“ system against perturbations or a decay. The effect is prominently  represented in black holes, in particular, stabilizing them against the Hawking decay as well as affecting the dynamics of mergers  and the spectrum of gravitational waves.  Due to this, it has spectacular implications for primordial black  holes, enabling  even the very light ones to be a viable dark matter.  The memory burden effect also  has implications for the spectrum of  cosmological quantum fluctuations in the early universe. 

Due to its universality,  the memory burden phenomenon and, in particular, its effect on the quantum entanglement  can be studied in ordinary quantum systems in the table top labs.
