Google has developed a quantum computer in 2019. It uses a 53 qubit quantum computer. As we know, it solves complex mathematical operations in seconds which the fastest super computers would take years to solve. And as we increase the qubits, the computing power would increase. Such computers have the capacity to change the world we live in. New drug discovery could be accelerated. New materials for superconductivity could be found. Agro-chemicals can be quickly developed. Encryption could become more effective. Teleportation could become a reality which is now a fantasy.
