EXCERPTS: Unlike descriptions of objects as having clearly defined locations and movements, a quantum perspective of the same particle describes features like its position, momentum, and spin as a blur of likelihoods. This 'cloud' of possibilities is best understood in isolation. Once the particle interacts with its environment its spread of possibilities changes like the odds of a runner winning the 100-meter sprint at the Olympics, until finally only one outcome is observed.
[...] quantum computers can theoretically exploit the spread of uncertainties in a particle to rapidly solve their own kinds of algorithms...
[...] The challenge lies in preserving the coherence of that quantum cloud of possibility – referred to as a qubit – for as long as possible. With every bump, every electromagnetic breeze, comes an increased risk of errors that ruin the number-crunching process.
[...] Time crystals are materials that transform in repeated patterns over time. ... In a paper available on the pre- peer review server arXiv, the trio of physicists proposes using the unique periodicity of a time crystal as the basis for a new kind of "time-tronics" circuitry. Used to guide the delicate waves of vast numbers of information-laden qubits, this periodicity could help reduce the accidental collisions that are responsible for many errors...
