Budget 2020: What is quantum computing and why it is importantUsing our example, if one qubit is equal to two, the second qubit would be 4, the third would 8, and so forth. On Saturday, the finance minister, in her Budget speech, said that India would spend Rs 8,000 crore over five years towards National Mission on Quantum Technologies and Applications. Its quantum machine, Sycamore, was able to do calculations in 200 seconds, what a conventional supercomputer would take 10,000 years to complete. Although the amount is low, to begin with, but given the advances in technology and India’s ability to create low-cost solutions, the money may suffice. Besides, with companies like D-WAVE offering quantum computers for $15 million (`113 crore), India can surely achieve these capabilities at lower costs. But the breakthrough in technology did not come till 1994, when Shor, developed a polynomial-time algorithm that may be able to break any cryptographic protocols. Since, then companies like Google, IBM have been engaged in developing a quantum machine that can operate Shor’s algorithm.
