This is interesting stuff, however the attention grabbing headline isn't supported by the content of the story.
Quantum mechanics provides a highly accurate description of a wide variety of physical systems. However, a demonstration that quantum mechanics applies equally to macroscopic mechanical systems has been a long-standing challenge, hindered by the difficulty of cooling a mechanical mode to its quantum ground state. The temperatures required are typically far below those attainable with standard cryogenic methods, so significant effort has been devoted to developing alternative cooling techniques. Once in the ground state, quantum-limited measurements must then be demonstrated. Here, using conventional cryogenic refrigeration, we show that we can cool a mechanical mode to its quantum ground state by using a microwave-frequency mechanical oscillator—a ‘quantum drum’—coupled to a quantum bit, which is used to measure the quantum state of the resonator. We further show that we can controllably create single quantum excitations (phonons) in the resonator, thus taking the first steps to complete quantum control of a mechanical system.

The OP is incorrect. This is not a proven "fact", it is just one interpretation of laboratory tests on quantum mechanics, conducted before WWII. There are many other interpretations based on theories that don't require additional spacial dimensions, or infinite parallel universes.
But it is pretty wild stuff. Those double-slit experiments are out of this world! (excuse the pun)
