Everything

An intermediary form of technology between mundane digital computers and hypertech Trinary computers, the quan­ tum computer employs quantum-mechanical phenomena in order to perform the usual computing tasks. Where current digital technology uses binary bits (0 or 1) that exist in one of two definite states, quantum computers employ qubits (quantum bits) that exist in a superposition of states that allows them to remain indefinite. Essentially, the typical computer says “yes

• slows the passage of time within a small localized bubble for two hours (Time 4 lag time).

/no,” the Trinary computer says “yes /no /maybe” (and these days, more), and the quantum computer theoretically says “all of the above.”

As of this writing, quantum computing still is largely theoretical. Working models have been built and employed in the real world, but they suffer from a number of physical and theoretical limitations. Physically, they’re huge, bulky, immobile things that require delicate conditions and enor­ mous amounts of space and energy. On the theoretical side, the Heisenberg uncertainty principle limits the quantum application potential of such machines; after all, if someone needs to view the results of a quantum computer’s functions, then that observer probably defines those results and takes them out of a superpositioned state! Tests with quantum computers have shown them to be marginally faster and more accurate than digital machines… but whether that speed and accuracy is the result of quantum-state phenomena or simply better components and conditions remains a source of debate.

In Mage, certain large, high-tech facilities probably em­ ploy quantum computers, if only to explore their possibilities and work those possibilities into the Consensus. Complex applications of Correspondence, Forces, Matter, and Prime could compress the titanic devices of mundane technology into smaller, portable machines. Even so, they remain delicate energy hogs with uncertain practical applications. From a rules standpoint, the Storyteller could declare that quantum computers allow a mage to use Sphere Ranks 4 and 5 without employing a Trinary device. Because the Trinary machines are smaller, more portable, and more reliable, however, they currently provide a superior technology to quantum computers.

Given the rapid pace of both mundane and Awakened technology, however, that edge might not last much longer.

The basic theory and practice of hacking has been covered above. In game terms, a character hacks a computer system using either Intelligence + Computer (for slow, methodical work), or Wits + Computer (when time is of the essence).

Perception + Computer can help reverse a system or obstacle, and Manipulation or some other Social Attribute + Computer can help a hacker socially engineer a solution… that is, find a workaround by influencing other people to help him do it.

In most situations, though, Intelligence + Computer does the job. See the Computer Systems chart (p. 118) for specific rolls, circumstances, and difficulties.
