In a quantum computer, it allows for qubits to hold not only  ones or zeroes, but many combinations of the two.
Its implications were challenged in the 1935 Einstein, Podolsky, and Rosen article titled ―Can Quantum-Mechanical  Description of Physical Reality be Considered Complete?‖ In a quantum computer, it allows for qubits to hold not only  ones or zeroes, but many combinations of the two. Generally, it states that if a particle can be in each of two states, then it can be in a combination of the two states. FTP, name this quantum principle, famously illustrated by Schrodinger‘s  simultaneously living and dead cat, and whose consequences include quantum entanglement and spooky action-at-a-  distance.
