Python week

Links to the tutorials (including one for those using Python version 3) and a statement of the coding assignment: week10.pdf.


For the record…

This week’s assignments.

Classical interlude

This week we’re in Harris and Harris Digital Design and Computer Architecture, available online from the Saint Mary’s College library.  You can download one chapter at a time in PDF format or the whole book for two weeks into Adobe Digital Editions (free software, follow the links).  Reading for Wednesday is Chapter 1, but no reading response questions.  Problems to come.

quantum teleportation

97 km across a lake in China.  The story from Ars Technica and the article from the ArXiv.

Nobel prize

Qubits, someday?  The 2012 Nobel Prize in physics has been awarded to two researchers for their work manipulating and measuring individual atoms and photons, without destroying them.  In the technical summary of the prize work, reposted here from the Nobel website, and in particular in the summary “boxes,” you’ll see manipulations of quantum states that look an awful lot like the ones we’ve been studying in class.  Only these guys have done them in actual physical systems.  The Nobel folks have also posted fun short interviews with the new prize winners (front page, scroll down).  Serge Haroche knows by heart the telephone country code for Sweden.

First circuits

Assignments for Chapter 5 are ready.  As follow-up from our last class, you may enjoy the Wikipedia article on experimental tests of Bell’s inequalities or the discussion in Greenstein and Zajonc, on course reserve at the library.

Into the EPR paradox

Don’t try this at home, kids.  The new assignment.
