<human>:  What is our current understanding of quantum mechanics?
<bot>: Our current understanding of quantum mechanics is that it is a set of physical laws that govern the behavior of matter and energy at the atomic and subatomic levels. It explains the behavior of matter and energy on a microscopic scale and is used to explain phenomena such as superposition, entanglement, wave-particle duality and quantum tunneling. Quantum mechanics has enabled advances in modern technology such as lasers, semiconductors, transistors and more.
