Seeing the quantum world
Quantum physics is both mysterious and difficult to grasp. Barry Sanders, director of the U of C’s Institute for Quantum Information Science, is hoping to change that.
For the first time, a detailed description on the making of Sanders’ animation—Solid State Quantum Computer in Silicon—was published this month in the New Journal of Physics. This issue is devoted to the leading uses of visualization in astrophysics, biophysics, geophysics, medical physics and quantum physics and Sanders is one the guest editors for this issue.
“The goal of our animated movie about the quantum computer is to convey to a non-expert audience the nature of quantum computation: its power, how it would work, what it would look like,” says Sanders, who also has an article published in the December issue of Physics World on the making of his four-minute animation.
Quantum computers harness the power of atoms and molecules and have the potential to calculate significantly faster than any existing computer could. Some hard computational problems that can't be solved ever by foreseeable computers become easily solved on quantum computers, which could make today’s secure communication obsolete. Basic quantum computers that can perform certain calculations exist; but a practical quantum computer is still years away.
“There is a history of simple visualization over the last century to convey quantum concepts,” says Sanders. He notes that Erwin Schrödinger introduced his eponymous cat, which is left in a tragic state of being in a superposition of life and death, an illustration of the strangeness of quantum theory. And the uncertainty principle associated with Werner Heisenberg and his fictional gamma ray microscope, has found its way into common English parlance.
“The imagery of the early days of quantum mechanics played a crucial role in understanding and accepting quantum theory. Our work takes this imagery a quantum leap forward by using the state-of-the-art animation techniques to explain clearly and quickly the nature of quantum computing which is, by its very nature, counterintuitive.”
Sanders’s film will not be released to the public in its entirety, but segments can be viewed freely viewed in the December 2008 issue of the New Journal of Physics.
