But the serious threats of quantum computing may emerge quicker than its possibilities. Security experts warn of the dangers of Q-day, when a quantum computer might crack the RSA cryptosystem, widely used by tech companies, banks and governments on their data.
Earlier this month, the heads of the “Five Eyes” spy agencies (the US, the UK, Canada, Australia and New Zealand) warned of the risks of China’s activities in quantum computing, AI and synthetic biology. “If you’re anywhere close to the cutting edge of tech, you might not be interested in geopolitics, but geopolitics is interested in you,” said Ken McCallum, director-general of Britain’s MI5.
Ever since 1994, when the mathematician Peter Shor wrote an algorithm that could run on a not-yet-invented quantum computer to crack RSA, security experts have worried about the world’s digital secrets. - https://www.ft.com/content/9ac38cf4-874e-4842-8be9-8fac2a3e898d
As with just about every powerful new technology, the question is not if but when the next quantum wave will be weaponized.
Quantum radar, code, internet, sensors and GPS are being fast-tracked by militaries and defense industries in all corners of the globe. Who gets there first (the quantum “haves”) could produce new asymmetries of power and dangers for the rest (the quantum “have-nots”).
Quantum communications systems can deliver completely secure, unhackable lines of communication. A prototype network is already connecting several major cities over nearly 5,000km in China. On the other hand, quantum computers pose the risk of eventually being able to hack classically encrypted messages in seconds – an eventuality known as “Q-Day.”
Quantum AI is being developed to improve the performance of lethal autonomous weapons. Do we really want swarms of drones operating in a networked battlespace without any humans in the loop?
Quantum sensors, already in use today, are able to make ultra-sensitive measurements of magnetic and gravitational fields. This means pinpointing metals and large objects underground as well as underwater.- https://www.inverse.com/tech/risks-of-quantum-technologies-unspoken
This will make a cashless society impossible meaning we can keep our cash and our freedom...for a little longer.

8. Organizations May Struggle To Find Needed Helium
,,,,The technology relies on helium-based cooling
The way it works, you say your password in a really, really high voice that no human can understand.
The #1 risk should be growth and intrusiveness of government. Government will show everything about you and what you are doing. It will enable global communism.
State of the art QC is nowhere near cracking RSA and it can most likely be extended/altered to make QC attacks impractical. On the other hand, all the older VPN traffic that the NSA has been hoovering up for decades will most likely be cracked at some point.
I’m afraid a hundred years from now kids will never see a helium ballon.
Yet another AI-generated Forbes article. And Google puts these fraudsters at the top of search results every time.
There is really only one risk,
and that is that people with nefarious intentions will use it to enslave others.
If you read “Quantum Supremacy: How the Quantum Computer Revolution Will Change Everything” by Michio Kaku you’ll also learn we have a distinct possibility to make huge progress towards cures of many forms of cancer, Alzheimer, and similar diseases. Not to mention not conducting tests on animals and substantial shortening lead time for drugs.
Thanx for the link up
Time to bring back paper,pencil and carrier pigeons for communications.
One day I hope to use Quantum computing to crack the bitlocker key on my external drive. It must be the drive I used on my work pc but after being retired 3 years I do not remember the login....
