Quantum state
In quantum physics, a quantum state is a mathematical entity that embodies the knowledge of a quantum system. Quantum mechanics specifies the construction, evolution, and measurement of a quantum state. The result is a prediction for the system represented by the state. Knowledge of the quantum state, and the rules for the system's evolution in time, exhausts all that can be known about a quantum system.

Physicists just made a breakthrough: quantum states that last over 5 seconds
Scientists made a breakthrough that could lead to more complex quantum calculations and even enable a "distributed quantum internet." A team of researchers, from the U.S. Department of Energy's (DOE) Argonne National Laboratory and the University of Chicago, were able to maintain a quantum state intact for more than five seconds, a new record for the field of quantum science, a press statement reveals.
