"Oh how I love a good gamble! But only when I win."
Edward Richtofen after receiving a "good" effect from the QED.


The Quantum Entanglement Device,[1] often abbreviated to QED, is a secondary tactical grenade appearing on the Zombies map Moon. The device, often called Quantum Bomb by the players, was invented by Edward Richtofen.

When thrown, the QED is capable of creating many different outcomes. Upon toss, the player will spin the handle on the bottom once, and push it in. It can either "curse" or "bless" the player, with outcomes such as extra weapons, extra perks, more enemies, or a reset of points.

Overview[]

QED

The Quantum Entanglement Device can only be obtained through the Mystery Box and takes up the player's secondary tactical grenade slot. It is one of two tactical Grenades on Moon, the other being the Gersh Device. The player cannot possess both; if the player attempts to take the Gersh Devices, any remaining QEDs will be swapped and vice versa.

The effect of the grenade is completely random, except in an instance where it is used against an Astronaut Zombie; if a QED goes off near one, it will always create an explosion capable of killing zombies.

Trivia[]

  • If the Zombies run over a "blessing" given by the QED, the players lose it with no way to recover the power up. If the Zombies run over a "curse", however, then the negative effect will still happen as if a player grabbed the power up.
  • It is possible to obtain a QED from a random weapon drop.
  • Throwing a QED at the excavator will deactivate it in rare circumstances.
  • In Black ops 3, similar to the Gersh Device, the QEDs can not be Pack-a-Punched using the Crate Power GobbleGum.
  • In his quotes, Richtofen claims the QED was stolen from him and was used against him. Such incident is not known.
  • Quantum Entanglement is a physical phenomenon lying in the heart of Quantum physics. In simple words, entanglement correlates and links the fate of particles, meaning influencing one particle will also influence particles that are entangled to it.
