Entropic uncertainty and measurement reversibility

Understand

The entropic uncertainty relation with quantum side information (EUR-QSI) from [Berta et al., Nat.

• Phys.
• 6, 659 (2010)] is a unifying principle relating two distinctive features of quantum mechanics: quantum uncertainty due to measurement incompatibility, and entanglement.
• In these relations, quantum uncertainty takes the form of preparation uncertainty where one of two incompatible measurements is applied.
