Min- and Max- Relative Entropies and a New Entanglement Monotone

Datta, Nilanjana

Understand

Two new relative entropy quantities, called the min- and max-relative entropies, are introduced and their properties are investigated.

  • The well-known min- and max- entropies, introduced by Renner, are obtained from these.
  • We define a new entanglement monotone, which we refer to as the max-relative entropy of entanglement, and which is an upper bound to the relative entropy of entanglement.
  • We also generalize the min- and max-relative entropies to obtain smooth min- and max- relative entropies.
