Quantum Entanglement Device

"Yay! This bomb-y thingy did something nice for Nikolai!"

- Nikolai Belinski

The Quantum Entanglement Device (QED) is a Wonder Weapon first seen in the Zombies level Moon, alongside the Wave Gun. It appears in the player's tactical grenade slot. Treyarch has stated that the QED will be able to "curse" or "bless" the player. It is currently unknown what exactly the QED does, nor how it will curse or bless the player. The QED has been shown to do multiple things, such as exploding like Matryoshka Dolls or exploding like a Scavenger shot.

Trivia

 * In physics, quantum entanglement is a phenomenon where two particles exchange information between each other without touching, regardless of the distance between them.
 * QED is also an abbreviation for "Quod erat Demonstrandum", which is Latin for "That which completes the proof.". However, it is possibly a coincidence.
 * The QED does not earn you points when it kills a zombie whereas other grenades do.
