Bit-flip and sign-flip codes are used in a form of “error correction” described by this adjective, which reduces information loss caused by decoherence. Hartmut Neven names a doubly exponential law for devices described by this adjective and oversaw a 2019 experiment at Google that claimed its (15[1])namesake “supremacy.” Devices described by this adjective can perform prime factorization using (*) Shor’s algorithm (10[1])much quicker than their classical (10[1])counterparts. (10[3])This adjective describes machines that use units (10[1])of information that can be entangled or exist in (10[1])superposition.
