Universe as quantum computer
A frozen accident supposedly froze quantum fluctuations to produce our universe.

How bio-friendly is the universe? P.C.W. Davies 2004
For example, if the value of the cosmological constant in our region of the universe is a frozen accident, and the probability of any particular value is uniformly distributed in the physically allowed range (this being >> the life-permitting range), then we might expect the actually observed value in our region to be not far from the threshold value at which life is permitted.
If the coupling to the environment is very strong, entanglement gets frozen in. What happens is that different energy levels of the system couple to each other via the environment, and this introduces a type of watchdog effect (McFadden, 2000) that freezes a region of the Hilbert space (a so-called decoherence-free subspace).

The Origin of the Genetic Code, Crick 1968
Amino acids were substituted when they were able to confer a selective advantage until eventually the code became frozen in its present form. The evolution of the code sketched here has the property that it could produce a code in which the actual allocation of amino acid to codons is mainly accidental and yet related amino acids would be expected to have related codons.

Frozen accident hypothesis
Frozen accident hypothesis assumes that the formation of the genetic code is an example of a frozen accident (Crick 1968) According to this hypothesis, the genetic code was formed through a random, highly improbable combination of its components formed by an abiotic route. The complicated nature of the proteosynthetic apparatus and the age of our universe mean that there is very low probability of the correctness such a hypothesis.

Crick proposed that a frozen accident created the genetic Code.

Simultaneous origin of homochirality, the genetic code and its directionality
Most theories of the origins of homochirality have assumed either the actions of a physical force (e.g. polarized light or magnetism) or a ‘‘frozen accident’’ that randomly set chiral preferences for one set of molecules.

Uncertainty of Prebiotic Scenarios: The Case of the Non-Enzymatic Reverse Tricarboxylic Acid Cycle: 26 January 2015
https://www.nature.com/articles/srep08009
The rTCA cycle that is found in bacteria is catalyzed by enzymes with high degrees of substrate selectivity. 28 The reaction substrates and the reaction sequence of the enzymatic rTCA cycle are conserved ( not evolved ) On the other hand, the transformations of pre biological chemistry are assumed to occur under the effect of chemical catalysts. The latter, however, are typically active with respect to certain types of chemical transformations and lack the high substrate selectivity characteristic of enzyme catalysts. The smallest supernetwork that includes rTCA cycle is designated the rTCA supernetwork. It contains 175 molecules and 444 reactions. We conclude that the rTCA cycle should have a low probability of a random realization. We also notice that its length and cost are close to extreme values. Selection for the extreme values implies an optimization process. Is there any evidence so far that such optimization will inevitably lead to the rTCA cycle?
My comment: Wow !! What a courageous admission !! I agree. Of course, there was no goal to have anything optimized. There was no urge of prebiotic molecules to transition to life
Further selection into biological cycles may have occurred by other means, such as a frozen accident, that is, the selection and preservation of a particular pathway from the ensemble of possibilities due to an undetermined random event
My comment: A frozen accident? That is the answer to those that have no meaningful, compelling, naturalistic explanation. So an ad-hoc assertion is made.

Photosynthesis and nitrogen fixation became evolutionarily immutable as “frozen metabolic accidents” because multiple interactions between the proteins and protein complexes involved led to their co-evolution in modules.
