"""
We have fixed the dates for the demo of our Orion quantum computing
system. We are going to hold two events, one at the Computer History
Museum in Mountain View, California on February 13th, and the second
at the Telus World of Science in Vancouver, Canada on February 15th...

Here is an optical picture of the processor we'll be using for the
demo. This particular circuit contains 16 qubits (the quasi-circular
loops arranged in a 4W4 array). Each of the qubits is coupled to its
nearest neighbors (N, S, E, W) and next-nearest neighbors (NW, NE, SW,
SE) via a tunable flux transformer, giving a total of 42 of these
couplers.

<NSA> use ECC!  it's more efficient and more secure!  really!
