We show that our lower bounds estimate the quantum entanglement better than some existing lower bounds by detailed examples. Moreover, our lower bounds can be experimentally identified without state tomography.

  We show that the incompatibility which is gained via additional measurements is upper and lower bounded by certain functions of the incompatibility of subsets of the available measurements.

  This paper aims to make a rigorous connection between the different low-degree and free-energy based approaches. We define a free-energy based criterion for hardness and formally connect it to the well-established notion of low-degree hardness. Results provide both conceptual insights into the connections between different notions of hardness, as well as concrete technical tools.

• Computable lower bounds on the entanglement cost of quantum channels [8.37609145576126]
  A class of lower bounds for the entanglement cost of any quantum state was recently introduced in [arXiv:2111.02438]. Here we extend their definitions to point-to-point quantum channels, establishing a lower bound for the quantum entanglement cost of any channel. This leads to a bound that is computable as a semidefinite program and that can outperform previously known lower bounds.
