|Quantum Entanglement Device|
950 (Mystery Box)
- "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, often abbreviated to QED, and called the Richtofen Device by Richtofen, is a secondary tactical grenade appearing on the zombie map Moon. The QED's effect is random. 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.
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 Gersch Device. The player cannot possess both; if the player attempts to take the Gersch Devices, any remaining QEDs will be swapped and vice versa. The effect of the grenade is completely random, and there is no known way of getting a certain outcome.

- It is necessary to have at least two QEDs to complete Richtofen's Grand Scheme.
- 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. Receiving this will replenish the player's QEDs or gives another player QEDs.
- The QED was invented by Edward Richtofen, as referenced in a quote he makes upon receiving the weapon.
