It’s reasonably acceptable to assume that an encrypted email can not be observed by prying eyes. That’s mainly because in get to split as a result of most of the encryption techniques we use on a day-to-day basis, until you are the supposed receiver, you would have to have the remedy to a mathematical dilemma that is just about unattainable for a laptop or computer to remedy in a reasonable amount of time.

Figure 1 shows already these new computing paradigms are becoming a reality and could soon be deployable. Hackers are already preparing by storing encrypted transactions now with the expectation they can decipher the information later.

Security is often managed today by key distribution systems in which one person sends information hidden behind a key, maybe a long string of seemingly unassociated numbers. The receiver of that information can access the information if they possess another specific key. The two keys are related in a mathematical way that is nearly impossible to guess, but can be easily solved with the right algorithm or using a quantum computer. [2]

The quantum nature of the electrons' transport adds some extra layers of security; if they are measured, the clock collapses. It will disappear forever and neither a spy nor the recipient can access the information.

Chakrabartty is working on some additional features for these chips, including the ability to self-destruct after a specified period of time. A provisional US patent for the technology has been filed by the Office of Technology Management.

Ultimately, SPoTKD could be used to make sure medical records are destroyed after being read by a doctor, or to enforce time limits on software licenses. They can secure voting records or validate NFTs or just make sure no one is reading your email. [3]
