Science – Quantum walks on a programmable two-dimensional 62-qubit superconducting processor
Abstract
Quantum walks are the quantum mechanical analog of classical random walks and an extremely powerful tool in quantum simulations, quantum search algorithms, and even for universal quantum computing. In our work, we have designed and fabricated an 8×8 two-dimensional square superconducting qubit array composed of 62 functional qubits. We used this device to demonstrate high fidelity single and two particle quantum walks. Furthermore, with the high programmability of the quantum processor, we implemented a Mach-Zehnder interferometer where the quantum walker coherently traverses in two paths before interfering and exiting. By tuning the disorders on the evolution paths, we observed interference fringes with single and double walkers. Our work is an essential milestone in the field, brings future larger scale quantum applications closer to realization on these noisy intermediate-scale quantum processors.

I'm very skeptical of us reaching post scarcity this decade.
I'm mildly skeptical of a exponential growth in technological development. Let alone double exponential.
Good, such achievements, progress from whatever country, is moving us humanity further. It's OUR progress.
We should grow up from this 'we they' mentality. We're all one, human civilization
I am quite confident that soon after we reach post scarcity (this decade, because of double exponential pace we see in growth of technology) nationalism will be dead, and considered something ancient, primitive, backward, stupid, feature of infant civilization.
Old generation(not all of them of course) may stick to this old, ancient "traditions" but young, global, 'generation of internet' mostly don't care about nationalism already, so this fact alone gives us a glimpse of nationalism, divisiveness politics fate
