Monogamy of entanglement is a principle in quantum information theory that describes a constraint on how quantum entanglement can be distributed among multiple parties. It essentially states that if two quantum systems (say, A and B) are maximally entangled, then they cannot share entanglement with a third system (say, C) at the same time.
