The Internet we use today is based on encryption. This means that your bank password, WhatsApp messages and online data remain locked in a “digital lock”. Normal computers cannot open this world. But, ‘Google’, one of the world’s largest tech companies, has given such a warning through its blog, which has given sleepless nights to cyber security experts around the world. But Google said that in the coming time, quantum computing can completely shatter this security system.

To understand quantum computers, it is necessary to first understand normal computers. Today’s computers work on “bits” (0 and 1). But quantum computers work on “qubits,” which can be in both 0 and 1 states simultaneously. For this reason, they can work on multiple paths at the same time and find the correct answer very quickly. This ability makes them many times faster than supercomputers.
