Question:
As we begin our study of the cryptology which underlies a PKI, we must be aware of new inventions in the field which might occur faster than predicted. According to NIST, the current crypto is expected to remain secure until 2030 ... but that could change rapidly if quantum computer advances faster than expected. The following article lays out an important development:

Even though this work is still in its nascent stages, today's technological developments move very rapidly. It is estimated that in just the next year, technology will make as much progress as was accomplished in the prior decade! And the same for the next year, and the next ... so effectively, by 2030, we will exceed a century worth of progress. So, it is important to understand that while we are learning about current public key technology, we keep an eye out for the advances which may make it obsolete.
Can you think of other things in your lifetime which have become obsolete due to technology?
Answer:
I remember the first time I learned about quantum computing, and as my Professor was explaining the concept, he paused to mention -- think about it, if a functioning quantum computer existed tomorrow, none of the information in cyberspace would be safe anymore. It's a stunning idea, but quantum computing reflects the pace at which technology is evolving today.
Speaking of cyberspace, how about all of the different ways in which people used to connect to the Internet? I remember using a dial-up modem with the loud sounds. And, if you only had one telephone line in your house, you had to temporarily agree to not receive phone calls in exchange for connecting to the Internet! Then you powered the dial-up modem off so that you could receive phone calls again. Imagining people only being connected for brief moments of time now seems so distant! Everyone usually has some Internet connected device on them almost always, and if it's not online through wi-fi, it's online through a data subscription.
Explanation / Answer
Your answer is totally good, but if you want you can add some more detailed points about quantum computing here they are -
After the invention of technologies and invention of new gadgets, this computing became relatively slow with respect to the new softwares and applications.The new hardware which was now being used in the devices also became a problem when it become tough for quantum computing to cope with the new hardware.
You can add these points and modify your answer in the following way -

Quantum computing studies theoretical computation systems (quantum computers) that make direct use of quantum-mechanical phenomena, such as superposition and entanglement, to perform operations on data. Quantum computers are different from binary digital electronic computers based on transistors.
Rather than store information using bits represented by 0s or 1s as conventional digital computers do, quantum computers use quantum bits, or qubits, to encode information as 0s, 1s, or both at the same time. This superposition of states—along with the other quantum mechanical phenomena of entanglement and tunneling—enables quantum computers to manipulate enormous combinations of states at once.

Similarly, After the invention of technologies and invention of new gadgets, this computing became relatively slow with respect to the new softwares and applications.The new hardware which was now being used in the devices also became a problem when it become tough for quantum computing to cope with the new hardware.
