Scientists observe a single quantum vibration under ordinary conditions

https://news.mit.edu/2019/single-quantum-vibration-normal-1007
Phonons, the individual particles of vibration described by quantum mechanics, are also associated with heat. For instance, when a crystal, made from orderly lattices of interconnected atoms, is heated at one end, quantum mechanics predicts that heat travels through the crystal in the form of phonons, or individual vibrations of the bonds

Vibrating atoms make robust qubits, physicists find

https://news.mit.edu/2022/vibrating-atoms-qubits-0126
MIT physicists have discovered a new quantum bit, or "qubit," in the form of vibrating pairs of atoms known as fermions. The new qubit appears to be extremely robust, able to maintain superposition between two vibrational states, even in the midst of environmental noise, for up to 10 seconds, offering a possible foundation for future quantum computers.

Physicists harness quantum "time reversal" to measure vibrating atoms

https://news.mit.edu/2022/quantum-time-reversal-physics-0714
The quantum vibrations in atoms hold a miniature world of information. If scientists can accurately measure these atomic oscillations, and how they evolve over time, they can hone the precision of atomic clocks as well as quantum sensors, which are systems of atoms whose fluctuations can indicate the presence of dark matter, a passing gravitational wave, or even new, unexpected phenomena.

It is the magic of quan-tization that makes these results possible. In string theory all particles—matter particles and force carriers—arise as quantum fluctuations of the relativistic string.

Phonon - Wikipedia

https://en.wikipedia.org/wiki/Phonon
A phonon is a collective excitation in a periodic, elastic arrangement of atoms or molecules in condensed matter, specifically in solids and some liquids.A type of quasiparticle in physics, a phonon is an excited state in the quantum mechanical quantization of the modes of vibrations for elastic structures of interacting particles. Phonons can be thought of as quantized sound waves, similar to

131 2. You are right the term "vibration" as used here is a self-declared folksy synonym for the technical "normal mode" or "phonon". You may, or may not, be invited to think of a specific note on a string and analogize its mathematics to that of quantum field theory, but your remonstrance obviates the pedagogical tack attempted. - Cosmas Zachos.
