Seeing the quantum world

19.12.2008
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.

Sanders, who is also the iCORE Chair of Quantum Information Science, has produced a four-minute animated movie with a team of animators and scientists. The film is intended for funding agencies, the public, and interdisciplinary teams building quantum computers, so they can see how a quantum computer would work and its underlying science.

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.

"The animation incorporates state-of-the-art techniques to show the science and the technology in the most accurate and exciting way possible while being true to the underlying principles of quantum computing,” says Sanders.

The animated movie was completed last year but the clips have not been publicly distributed before now.

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.

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

Im Focus: Lining up surprising behaviors of superconductor with one of the world's strongest magnets

Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur

What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...

Im Focus: World record: Fastest 3-D tomographic images at BESSY II

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.

Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...

Im Focus: A molecular switch may serve as new target point for cancer and diabetes therapies

If certain signaling cascades are misregulated, diseases like cancer, obesity and diabetes may occur. A mechanism recently discovered by scientists at the Leibniz- Forschungsinstitut für Molekulare Pharmakologie (FMP) in Berlin and at the University of Geneva has a crucial influence on such signaling cascades and may be an important key for the future development of therapies against these diseases. The results of the study have just been published in the prestigious scientific journal 'Molecular Cell'.

Cell growth and cell differentiation as well as the release and efficacy of hormones such as insulin depend on the presence of lipids. Lipids are small...
