When the Institute for Quantum Information (IQI) was founded in 2000, we needed a logo, and (then) graduate student Andrew Landahl volunteered to produce one:

It served us well, and even today the Landahl Logo is emblazoned on hats worn by scientists all over the world.

In 2011, when the IQI became part of our larger new center, the Institute for Quantum Information and Matter (IQIM), a new logo was clearly needed. For a while, other business prevented us from focusing appropriate attention on this task, but this fall Spiros and I worked with the talented graphic designer Margaret Sanchez to create an image that would convey the essence of the IQIM in a visually appealing way.

We decided that the logo, rather than representing any concrete physical system, should instead portray the active role of the observer in the quantum measurement process. And so we eventually settled on:
