Absolution Gap (Revelation Space, #3)

by Alastair Reynolds

The cryo-arithmetic principle was based on a controlled violation of thermodynamic law. It was an outgrowth from quantum computation, exploiting a class of algorithms discovered by a Conjoiner theorist named Qafzeh in the early years of the Demarchist war. Qafzeh’s algorithms—if implemented properly on a particular architecture of quantum computer—led to a net heat loss
