It is well known that hydrogen bonds have a strong classic component coming from electrostatics. However, its quantum component can be exceptionally prominent due to the zero-point motion of light hydrogen nuclei (proton), which is a natural result of the Heisenberg uncertainty principle. Therefore, the assessment of nuclear quantum effects has been a key issue for understanding the structure, dynamics, and macroscopic properties of water. Despite enormous scientific efforts in past decades, it still remains an open question to what extent the quantum motion of the hydrogen nuclei can affect the hydrogen bon
