You have unlocked the secret to creating Nuka-Cola Quantum. With this perk, every ten Nuka-Colas in your inventory is immediately converted into a Nuka-Cola Quantum.— In-game description

Quantum Chemist is a perk in the Fallout 3 add-on Broken Steel.


With this perk, every 10 Nuka-Colas that the player character acquires are automatically converted into a Nuka-Cola Quantum. A notification in the top left of the screen will inform the player of the 10 Nuka-Colas being removed and the 1 Nuka-Cola Quantum being added. If attempting The Nuka-Cola Challenge, it takes 300 Nuka-Colas to get the necessary 30 Nuka-Cola Quantums.


  • This perk allows the player to circumvent the hard limit of Nuka-Cola Quantums placed in the game (94 loose in the world, plus the possibility of finding up to 152 in vending machines). Since regular Nuka-Colas can be found restocked in merchant inventories, this perk allows for a potentially unlimited number of Quantums.
  • With this perk, gaining the third Nuka-grenade schematic will result in receiving three grenades for each bottle of Quantum, equating to a "cost" of just over three bottles of Nuka-Cola per grenade.
  • Ice Cold Nuka-Cola is not affected by this perk.
  • In the game, the Science skill requirement is not noted for this perk.
  • Mississippi Quantum Pie can also be made in great numbers with this perk.
