Your mother was born on this date in 1918. You are facing west under the
shade of a couple very old oak trees near the center of Rose Hill Cemetery. You
took a shorter walk and Carol took a longer one.
1054 hours. We have returned from our walk. It is another wonderfully
crisp morning, another comfortable day. I have been doing my exercises fairly
regularly even while I am walking. I feel better in the process. It is very
pleasant having the windows open for a few days and nights; another night with
the blanket -- warm and toasty.
Check your email, check those chairs you
painted yesterday, and stop concerning yourself with my comment "Whatever
works," I am not being Machiavellian here. We don't worship words, you do.

Words are a continual problem. Sometimes a particular word in context;
hinders or helps depending on who is doing the reading. It would be interesting
to see how the Marsupial humanoids handle this problem of 'meaning open to
interpretation. I don't remember any lawyers on the planets but I imagine they
have some. Sometimes I think we have two many words, other times not enough. In
fact, the further along our species exists the more words we accumulate and the
more layers of meanings in a particular context finds humor or anger or maybe
both. What would Jonathon Swift do in such a day as ours today or in your
tomorrows? The best way for me to handle this mode I'm in is to let it go like
yesterday's newspaper. News is only good once.
And bad news hangs on for generations. -

Quantum Computers Will Give
Artificial Intelligence Big Boost, Studies Suggest

Quantum computers of the
future will have the potential to give artificial intelligence a major boost, a
series of studies suggests.
These computers, which encode
information in 'fuzzy' quantum states that can be zero and one simultaneously,
have the ability to someday solve problems, such as breaking encryption keys
beyond the reach of ‘classical’ computers.
Algorithms developed so far
for quantum computers have typically focused on problems such as breaking
encryption keys or searching a list — tasks that normally require speed but not
a lot of intelligence. But in a series of papers posted online this month on
the arXiv preprint server, Seth Lloyd of the Massachusetts Institute of
Technology in Cambridge and his collaborators have put a quantum twist on AI.
The team developed a quantum
version of 'machine learning', a type of AI in which programs can learn from
previous experience to become progressively better at finding patterns in data.
Machine learning is popular in applications ranging from e-mail spam filters to
online-shopping suggestions. The team’s invention would take advantage of
quantum computations to speed up machine-learning tasks exponentially.
Quantum leap
At the heart of the scheme is
a simpler algorithm that Lloyd and his colleagues developed in 2009 as a way of
quickly solving systems of linear equations, each of which is a mathematical
statement, such as x + y = 4. Conventional computers produce a
solution through tedious number crunching, which becomes prohibitively
difficult as the amount of data (and thus the number of equations) grows. A
quantum computer can cheat by compressing the information and performing
calculations on select features extracted from the data and mapped onto quantum
bits, or qubits.
Quantum machine learning
takes the results of algebraic manipulations and puts them to good use. Data
can be split into groups — a task that is at the core of handwriting- and
speech-recognition software — or can be searched for patterns. Massive amounts
of information could therefore be manipulated with a relatively small number of
qubits.
"We could map the whole
Universe — all of the information that has existed since the Big Bang — onto
300 qubits," Lloyd says.
Such quantum AI techniques
could dramatically speed up tasks such as image recognition for comparing
photos on the web or for enabling cars to drive themselves — fields in which
companies such as Google have invested considerable resources. (One of Lloyd's
collaborators, Masoud Mohseni, is in fact a Google researcher based in Venice,
California.)
“It's really interesting to
see that there are new ways to use quantum computers coming up, after focusing
mostly on factoring and quantum searches,” says Stefanie Barz at the University
of Vienna, who recently demonstrated quantum equation-solving in action. Her
team used a simple quantum computer that had two qubits to work out a
high-school-level math problem: a system consisting of two equations. Another
group, led by Jian Pan at the University of Science and Technology of China in
Hefei, did the same using four qubits.
Putting quantum machine
learning into practice will be more difficult. Lloyd estimates that a dozen
qubits would be needed for a small-scale demonstration.

[Thank
you Doug, for sending this on. I'm pumped on quantum computer concepts. What
will civilization be like in 20,000 years? So very cool to contemplate. I
wonder what Ship thinks?]

Let's work that
into Pouch 20, boy, when you get around to it. Post. - Amorella
Sometimes you make me nervous making a comment like this. (1805)
2211 hours. We watched last night's Masterpiece
Theatre's "Endeavor" with Morse as a young detective and then
"Unforgettable" finally back on the air after more than a year off.
We had lunch leftovers for supper during the news. I received another note from
Doug reminding me of Schrodinger's cat. I had made a reference to it but
couldn't remember the man's name. I know I have mentioned him several times
before. Doug's comment is:
** **
". . . Yes it is still a difficult
concept for me to understand. How one object can be in two places at the same
time and how a computer register can both be 1 and zero at the same time, the
cat is both dead and alive."
From Doug's note today.

Schrödinger's
cat: a cat, a flask of poison, and a radioactive
source are placed in a sealed box. If an internal monitor detects radioactivity
(i.e. a single atom decaying), the flask is shattered, releasing the poison
that kills the cat. The Copenhagen interpretation of quantum mechanics implies
that after a while, the cat is simultaneously
alive and dead. Yet, when one looks in the box, one sees the cat either
alive or dead, not both alive and dead. This poses the question
of when exactly quantum superposition ends and reality collapses into one
possibility or the other.

hours. What if the quantum superposition never ends? What if that is the way it
is for the soul? I wonder if Ship can work that into Pouch 20?
That will be something for you to mull over
before you go to sleep, orndorff. As long as Ship uses several of these points
as analogous suppositions or working hypotheses within the greater framework of
inductive logic it may be entertaining to consider. - Amorella
I think I may be mistranslating you tonight Amorella. I'm waiting until
morning to mull this over. I'm tired and it's time for bed.
Tomorrow then, post. - Amorella
2235 hours. It is hard to hold these abstractions in my head, Amorella.
I need to solidify them for enough self-understanding so they might be put to
use for machinery built or made 20,000 years from now. Presently I don't feel
very credible.
Very credible, then you must feel
somewhat credible to accept such a presentation in Pouch 20. - Amorella
I have no idea.
Now,
this statement coming from you has some dark humor embedded. Good night,
orndorff. - Amorella
I am not sure I understand what you are saying here. I don't see the
humor.
Of course not. - Amorella
