- Paper published in Nature Scientific Reports shows that optimization problems in biophysics can be solved with a quantum computer
BURNABY, British Columbia and MILPITAS, Calif., August 14, 2012 /CNW/ - In a paper published yesterday in Nature Scientific Reports, http://www.nature.com/srep/index.html, a team of Harvard University researchers, led by Professor Alan Aspuru-Guzik, presented results of the largest protein folding problem solved to date using a quantum computer. The researchers ran instances of a lattice protein folding model, known as the Miyazawa-Jernigan model, on a D-Wave One™ quantum computer.
"It's gratifying to see that our machine can be used to serve the scientific community in this way," stated Dr. Geordie Rose, D-Wave CTO and Founder.
"The D-Wave computer found the ground-state conformation of six-amino acid lattice protein models. This is the first time a quantum device has been used to tackle optimization problems related to the natural sciences," said Professor Alan Aspuru-Guzik from the Department of Chemistry and Chemical Biology at Harvard University.
Proteins contribute to virtually every process that occurs within a cell. The shape of a protein is closely related to its function. Understanding the shape of a protein helps researchers understand how it behaves, accelerating advances in many different areas of life sciences, including drug and vaccine design.
A cornerstone of computational biophysics, lattice protein folding models provide useful insight into the energy landscapes of real proteins. Understanding these landscapes, and how real proteins fold into the shapes that help give them their function, is an extremely difficult problem for today's computers to solve.
Dr. Alejandro Perdomo-Ortiz, the lead author of the paper, stated that: "Knowing that we can use real quantum computers to solve hard problems in biology is an exciting and important result. The techniques developed in this report can also be used to tackle other biophysical problems such as molecular recognition, protein design, and sequence alignment."
