"Singleton" is a science-fiction short story by Australian writer Greg Egan,[1] first published in Interzone 176 in February 2002.
Parallel, he develops the qusp (Quantum Singleton Processor) only carrying out a single calculation without making alternatives real.
He discusses with Francine an operation enabling her to have children after the miscarriage again, but they decide to instead use the qusp to raise an AI child.
[4] Karen Burnham, writing in The New York Review of Science Fiction, concludes after a discussion of the short stories "Axiomatic", "Mister Volition" and "Singleton", that "not everyone is as sanguine about the continuity of consciousness when making the transition to substances other than our organic brains nor so worried about the moral implications of the many-worlds interpretation of quantum physics."
She claims that "Egan’s stories show a continuity of concern about these subjects that refuses superficial answers and instead examines them in depth.
