On the ...

Copiale cipher; Dictionary coder – lossless data compression algorithms which operate by looking for matches between the text to be compressed and a set of strings (“dictionary”) maintained by the encoder; such a match is substituted by a reference to the string’s position in the set; Leet
[35] [36] In 2012, ISI's Kevin Knight spearheaded a successful drive to crack the Copiale cipher, a lengthy encrypted manuscript that had remained unreadable for 250 years. [37] Also in 2012, the USC-Lockheed Martin Quantum Computing Center (QCC) became the first organization to operate a quantum annealing system outside of its manufacturer, D ...
The ciphers' increasing "complexity" through the entrance into the courtyard is intended to be as if it "were a fossil". [3] Other elements of Sanborn's installation include a landscaped garden area, a fish pond with opposing wooden benches, a reflecting pool , and other pieces of stone, including a triangle-shaped black stone slab.
