Inspirations from a Theoretician’s Life

Brainstorming ideas from my former life as a theoretical physicist (once a physicists, always a physicist?) that might serve as some sort of design inspiration.

Quantum error correcting codes

Peter Shor came up with the original 9 qubit quantum error correcting code

By trying to put it on a lattice, I discovered that it could be changed into a different kind of code, that was both more complicated conceptually, but simpler when implemented

And when you try the same thing on Archimedian tilings, you get all sorts of fun codes

Communication cost of simulating entanglement

Protocols for simulating measurements on a Bell pair use some interesting geometry on spheres

To figure out how these protocols work, Ben Toner and I used some fun integrals

Exchange interactions

Back in my Ph.D. days I thought a lot about exchange interactions.  This is an interaction that acts to exchange two qubits, and while it would seem to not be that powerful it turns out that you can build a quantum computer just using exchange interactions.  These looks like hills, but its really how to perform a controlled-phase gate using only exchange interactions

Into the Third Dimension

The two dimensional subsystem code, has a few three dimensional cousins, of which here is one.

Local subsystem codes (unpublished)

This is a dictionary of sorts for turning a quantum circuit into a quantum subsystem code

It yields interesting constructions.  Here a cat state is used to measure a four qubit stabilizer

Photos, Oct 5-7, 2012

We closed on Oct 2, and were out to visit the property the following weekend.

Here is the view from the very SE corner of the property looking NW.  The likely building spots are at the end of the trees.  The bench that this is sitting on runs roughly SE-NW.

For sale no more!

Some of the trees (a few are in rough shape, but most seem healthy)

Another shot of the trees.  Building site  right in this area.

More trees:

The Test Dog thought she had died and gone to dog heaven.  For a dog whose very favorite thing to do (after eating, of course) is to run through tall grass this was like Disneyland.

A happy Test Dog

Walking the property I came upon a nice family of ants who had already decided on their own building site:

Ant hill

Directly below the trees and the building site is a lower bench.  The bench has two (locust?) trees

Lower bench

Tree with Mt. Garner and either a bug or a bird caught in flight

Locust tree with Mt. Gardner in background

Here is a shot from just below the trees.  Looking at satellite images my guess is that this meadow gets pretty wet and boggy during the spring melt-off.

I walked the entire property line (20 acres is quite a lot of land).  Here is a marker on one of the corners of the property.

Random Skiing Links

Some links about skiing:

  • Backcountry skiing route just up the road Cougar Mountain Ski Tour
  • Map of the MVSTA Rendezvous trails that also start just up the road.
  • Youtube of some X-countrying on the Rendezvous trails, complete with funked out music:

Mountains

Labeled mountain, peaks, and ridges.  I believe the area above Sun River Lodge is call Thompson Ridge.  The mountains visible through the crease above Virginia Ridge are unlabeled mountains north of Midnight Mountain.  Off camera to the left, up hill, is Lewis Butte.  Still looking for the name of the small pond.  Also would like to know the treed mountain to the west of the Gardner Mountains.  Click for a larger picture.
