Quantum coherence is an interference between these different possible future histories of the object. However, this interference can exist only until the system is observed or disturbed.

As it leads the charge toward bigger, better and faster quantum computers, IBM built the biggest chip (and the biggest fridge) yet. Then it changed course.

The main objective of this recent study by Yu and his colleagues was to realize quantum skyrmions using a deterministically coupled quantum dot-based microcavity system.
