The Coming of the Quantum Cats is a 1986 science fiction novel by American writer Frederik Pohl. It was originally serialized in Analog science-fiction magazine, January-April 1986.


Plot introduction

The novel hinges around invasions from alternate Earths in alternate universes. None of these universes are quite like our universe; however, they all have some element or other in common, many of which Pohl develops to satiric effect.

  • In one universe Nancy Reagan is the President of the United States and her mostly-disregarded husband Ronald is known as "The First Gentleman". John F. Kennedy is a Senator from Massachusetts who is married to a woman called Marilyn.
  • In another universe, America's political spectrum has shifted far to the right, and Ronald Reagan is regarded as dangerously left-wing.
  • In the past of some of the worlds, the young revolutionary Joseph Dzhugashvili (not known in these worlds as Stalin) had escaped from Russia to America in the 1900s, taking with him the proceeds of a bank robbery conducted on behalf of the Bolsheviks and using the money to set himself up as a big American capitalist.

The book presents multiple versions of three characters -- Dominic DeSota, Nyla Christophe, and Larry Douglas -- and their interactions as different versions of the characters travel from one Earth to another. Dominic DeSota is the main character, with most of the book told from the divergent viewpoints of three of his avatars (see following), with brief glimpses of numerous additional Dominic DeSotas scattered throughout the novel as anything between a nuclear scientist and a hunter scrabbling for bare existence in the ruins left after a nuclear holocaust.

The book seems to argue in favor of the idea that social conditions rather than heredity are what shapes a person's character and behavior (the Nature versus nurture debate). As depicted again and again in the course of the book, people born with precisely the same genetic heritage can - given different social conditions - develop completely different character traits (timid or assertive, benevolent or predatory, etc.) In that, it has a similarity of theme with the otherwise very different Cyteen by C. J. Cherryh, published two years later (1988).


Origin of the title

The title refers to the famous thought-experiment known as "Schrödinger's Cat" where the outcome of a real-world event depends on a quantum event. By some interpretations the real-world object, in this case a cat, must be in two states simultaneously until it is observed. However the story is more closely related to the many-worlds interpretation of quantum mechanics where all possible outcomes of an event occur, each in its own parallel universe. The same concept was treated, somewhat more pessimistically, in Larry Niven's short story "All the Myriad Ways".

Plot summary

The novel begins with Nicky DeSota, a timid mortgage broker in a fascistic America who draws the unwelcome attention of Nyla Christophe, an FBI agent investigating a break-in at a government lab by what proves to be a Dominic DeSota from an alternate universe. Used as a pawn by Christophe's con-man boyfriend Larry Douglas to entrap an activist former actor (who turns out to be Ronald Reagan), he is later detained and brought to New Mexico to unravel a mystery.

The focus then shifts to another Dominic DeSota, a United States Senator having an affair with Nyla Christophe Bowquist, who in this world is a famous violinist. Contacted by the military, he travels to Sandia National Laboratories, where he meets an identical version of himself -- a "Cat" from an alternate universe. As Senator DeSota interviews his alternate-universe counterpart, the man vanishes after offering a cryptic warning. As the senator leaves the building, he and the base commander are captured by a detachment of troops led by Major Dominic P. DeSota, the commander of a military force from yet another universe.

Major DeSota's mission is revealed to be to secure the parallel-world research facilities of Senator DeSota's universe, which is the first step in a larger military operation. In Major DeSota's universe (which is subsequently designated Paratime Gamma) a militaristic United States is engaged in a tense standoff with the Soviet Union, and wants to use Senator DeSota's universe (Paratime Epsilon) to launch sneak attacks against them. After being transported to Paratime Gamma, Senator DeSota manages to escape by distracting his guard (Gamma's version of Nyla Christophe) and escaping through a portal with a scientist to Paratime Tau -- the home universe of Nicky DeSota.

After being discovered in the desert, Senator DeSota and the scientist -- who is Larry Douglas from another universe -- are captured and interrogated by Agent Christophe. In an interrogation session involving the senator, the scientist, and their counterparts from Paratime Tau, Douglas reveals that he is from Paratime Alpha, and that he was forced by the military in Paratime Gamma to give them the ability to travel between universes. As Agent Christophe begins to pressure Douglas to give her government similar assistance, she and the other FBI agent with her are rendered unconscious by knockout darts fired by Dominic DeSota -- the same Dominic DeSota who had escaped interrogation in Sandia.

DeSota brings the entire group back to his universe -- Paratime Alpha -- where he explains that since the senator's escape that Paratime Gamma has invaded the Epsilon's Washington D.C. in a failed bid to capture the president. He also reveals that travel between universes is creating a growing problem of "ballistic recoil," where the boundaries between the universes is growing weaker, causing matter and energy to cross unintentionally from one universe to the next (something depicted in interludes between the chapters). He brings the travelers to Washington D.C., where they cross over to Paratime Epsilon in an effort to help stop the invasion.

Before they can help, however, every "Cat" located in a different universe disappears, along with any scientists involved in paratime research. There they are informed that they have been transported by a group of more advanced alternate Earths in order to stop ballistic recoil before it escalates and the barriers between universes become irreparably permeable. The "Cats" are relocated to New York City on a new Earth, one being resettled after its inhabitants wiped themselves out. There the paratime transplants gradually settle into new lives.

Six months after his arrival, Nicky DeSota returns to New York to propose to Agent Christophe. Now working on a collective farm in Palm Springs, he has embraced the opportunity for a new life and developed into a much more confident man. After considering his proposal, the Nyla of his world accepts. On their trip back to California, however, Nicky reveals to her his expectation that their transplantation has not solved the problem of paratime travel -- that with an infinite number of Earths, the number of them that will develop the ability to cross into alternate worlds will only increase, so many that the problem of ballistic recoil may prove to be unavoidable.


  • Nicky DeSota, Senator DeSota, Major Dominic P. DeSota, Dominic DeSota-Arbenz - versions of Dominic DeSota, being respectively a mortgage broker, a US Senator, an Army officer and a traveller among the parallel worlds. The last of these belongs to an enlightened society where it is customary for a husband to add his wife's family name after his own.
  • Nyla Christophe (3 versions) who are Nicky DeSota's FBI tormentor, Dominic DeSota's mistress, and Major DeSota's aide (who is in love with her boss).
  • Larry Douglas a.k.a. Lavrenti Dzhugashvili, (3 versions), boyfriend of a Nyla, a friend of Senator DeSota (as Lavrenti), and a captive scientist. All are grandsons of alternate versions of Iosif Vissarionovich Dzhugashvili , known in our Universe as Stalin.
