aarondubrow writes "Because quantum systems become unstable quickly, their error threshold is an important factor. How many bits can 'break' before the system stops working? An international team of researchers used the supercomputers at the Texas Advanced Computing Center to simulate the error threshold of a topological quantum system and found a much higher threshold than had previously been reported."
egrep patterns are full regular expressions; it uses a fast deterministic
algorithm that sometimes needs exponential space.
