What Coffee With Cream Can Teach Us About Quantum Physics

0 30

Researchers at the University of Colorado Boulder have discovered a new way to store information in quantum computer chips. The team used math to show that scientists could create a scenario where milk and coffee never mix, no matter how hard they stir them. This discovery may lead to new advances in quantum computer chips, potentially providing engineers with new ways to store information in incredibly tiny objects.

The study, which includes co-authors David Stephen and Oliver Hart, is a major step forward for physicists seeking to create materials that remain out of balance or equilibrium for long periods of time, a pursuit known as “ergodicity breaking.” Quantum computers, in contrast, employ “qubits,” which can exist as zero, one, or zero and one at the same time. Engineers have made qubits out of various things, including individual atoms trapped by lasers or tiny devices called superconductors.

Qubits can become easily mixed up, and if all qubits are turned to one, they will eventually flip back and forth until the entire chip becomes a disorganized mess. In the new research, Nandkishore and his colleagues calculated that if scientists arrange qubits into particular patterns, these assemblages will retain their information even if they are disturbed using a magnetic field or a similar disruption. This could allow engineers to build devices with a kind of quantum memory, storing information in patterns that cannot be degraded.
