In this superposition they are both 0 and 1. Sometime they can be entangled, and they share physical properties even if they are separated by large distance. Though this behaviour doesn\u2019t exist in classical physics.&nbsp; In quantum physics this superposition get vanishes when the experimenter interacts with each other. Based on superposition a quantum computer with minimum 100 qubits can display 2100 solutions simultaneously. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Google has recently announced this fall to its fanfare that it had already demonstrated \u201cQuantum Supremacy\u201d which can perform a specific quantum computation better than classical computers.
