A team of quantum computer physicists at UNSW Sydney has engineered a quantum processor at the atomic scale to simulate the behavior of a small organic molecule, solving a challenge set some 60 years ago by theoretical physicist Richard Feynman.
The achievement, which occurred two years ahead of schedule, represents a major milestone in the race to build the world's first quantum computer, and demonstrates the team's ability to control the quantum states of electrons and atoms in silicon at an exquisite level not achieved before.
In a paper published today in the journal Nature, the researchers described how they were able to mimic the structure and energy states of the organic compound polyacetylene—a repeating chain of carbon and hydrogen atoms distinguished by alternating single and double bonds of carbon.
