When quantum systems, such as those used in quantum computers, operate in the real world, they can lose information to mechanical vibrations. New research led by Michigan State University, however, shows that a better understanding of the coupling between the quantum system and these vibrations c
Michigan State University researchers have discovered how to utilize vibrations, usually an obstacle in quantum computing, as a tool to stabilize quantum states. Their research provides insights into controlling environmental factors in quantum systems and has implications for the advancement of quantum technology.
For instance, even light can cause information leaks if it has enough energy to jiggle the atoms within a quantum processor chip.“Everyone is really excited about building quantum computers to answer really hard and important questions,” said Joe Kitzman, a doctoral student at Michigan State University. “But vibrational excitations can really mess up a quantum processor.”, Kitzman and his colleagues are showing that these vibrations need not be a hindrance.
Although that may sound like cheating, it’s well within the rules of quantum mechanics. Still, this feature should give quantum computers valuable advantages over conventional computers for certain problems in a variety of areas, including science, finance, and cybersecurity.Beyond its implications for quantum technology, the MSU-led team’s report also helps set the stage for future experiments to better explore quantum systems in general.
“We’re creating a paradigm system to understand how this information is scrambled,” said Pollanen. “We have control over the environment, in this case, the mechanical vibrations in the resonator, as well as the qubit.”

Physicists use a 350-year-old theorem to reveal new properties of light wavesSince the 17th century, when Isaac Newton and Christiaan Huygens first debated the nature of light, scientists have been puzzling over whether light is best viewed as a wave or a particle—or perhaps, at the quantum level, even both at once. Now, researchers at Stevens Institute of Technology have revealed a new connection between the two perspectives, using a 350-year-old mechanical theorem—ordinarily used to describe the movement of large, physical objects like pendulums and planets—to explain some of the most complex behaviors of light waves.
