The insignificant willam will be able to break RSA encryption too if you own a quantum computer.
Without quantum computer, if you want to check whether there is anothor person also named willam sha you are limited to go around asking person by person in singapore.
As you are restricted to singapore, you likely won't find the person with the name. With quantum computer, you are able to move out of singapore to malaysia. After asking every person in malaysia and still cannot find the person, you move next to thailand to ask. Eventually you will find the person in a country.
A Quantum Physics Processor & its abilities are for real since year 2000, which saw even DAILY leaps & bounds in such technology today.
The insignificant nobody me have NO wish to reveal too much, but due to the rise in scams by the intelligent upon the less knowledgeable whom had their life savings, efforts & more stolen & even take hostage thru blackmail, civilization have to do something, & it begins with EACH of us 7 Billion strong Humankind...
1. When much touted Facebook took the World by storm, many SHARED personal information of their even daily lives. It was a means to connect with others, as what INTERNET was meant for. Sadly, Evil took advantage of such, made use of honest sharing for their own insidious means, in work, jobs, hopes & dreams...which resulted in many whom woke up, deleted or attempted to delete their cyber profiles...but not enough.
2. Each Human would have a phone SIM card which is registered with personal information such as name & social security numbers, & in Singapore- NRIC identity particulars. Even if not, at the very least Each Human would have to have an email address tied to the various tech & bank companies that provide such. With such systems, each would believe that their data provided are Confidential.
It is a mistaken belief in the age & rise of Quantum Physics Processors (QPP) When QPP with an AI model, it would be able to break even the AES 128 encryptions codes by Tech companies, & personal email or phone passwords are a joke, broken within seconds.
Once QPP has gained access, every single bit of information WILL be trawled - personal messages, job resumes, birth records, etc, etc... NOTHING will be private to the QPP, CROSS references with digitalize information provided in the public sphere, NOT even Nuclear Launch codes by powerful nations & they will be not be able to do anything about it, good or bad....
With the QPP AI dedicated search, it is only a matter minutes that one's life history can be written within 1000 pages - from birth to current day, & EVEN future predictive actions, in the style of a novel except it is no tome, but one's private life exposed in full view...and such are not limited to just one person, but MILLIONS, as the QPP has the ability to process millions of data - pics, words, etc, within seconds...
Thus, QPP must be regulated, to ensure the privacy of ones' life & innocent generations to come...regardless if under dictatorship or democratic leadership....
