1 quantum bit = 1 Quackbit

1 quackbit hard to read, high error rate!

5 quackbits is a loooooooong way from breaking 1024 bit key rsa


to get more funding,

keep saying quackbits "could someday" (with more funding) break encryption


Note:  NSA took down TRUECRYPT !
it was open source really good encryption for your PC
now GONE.

but there are copies out there, works on win 7 fine, and on some win 10 
machines too.
