Quantum computing EXPLAINED | The future is here

Quantum computing in 2022 is gathering momentum and while the practical applications are yet very scarce, the quantum future is set to break the current cybersecurity infrastructure… or will it re-invent it? Let’s get the quantum hype debunked.

⭐ Quantum computing today
Companies like Google and IBM are pushing advancements, each bragging of having the fastest quantum computer 2022. There are roadmaps of the quantum future, with faster and more powerful computers being developed every day… What seemed questionable to Einstein over 100 years ago, is now our new reality.

❓ What are quantum computers?
Classical vs quantum computing are two very different things. If you take a regular computer and pick the technology apart to the very base, you’ll run into ones and zeros - that’s the binary system. Every operation, every single calculation boils down to the same two numbers - and the results will always have the same two outcomes.

Quantum computing, however, uses quantum bits, or in short - qubits. The operations happen on a way smaller scale - the particles are faster and have unique properties - and it all adds up to quantum computers being faster.

💥 Dangers of quantum computing
According to CSA, once this countdown runs out, quantum computers are set to break the cybersecurity infrastructure, at least the one we know today.

Here’s why quantum computing is so dangerous – in theory, quantum computers would be able to break 2048-bit RSA encryption in just under 8 hours. A classical supercomputer would tackle the same task for 300 trillion years.

🔑 What about quantum cryptography?
Where quantum technology poses a challenge, it also creates a solution. Quantum cryptography applies the principle of quantum mechanics and the purpose of it is not to break encryption - rather, to create it.

The technology itself is fairly complicated, but it boils down to one specific advantage - any eavesdroppers can’t read, forward, or copy the information without altering it. However, post-quantum cryptography is facing challenges - so while there is a possibility for it to be unhackable, there are still ways to go.

What do you think about Quantum Computing? Do you think it will change the future?

Good introduction into quantum computing and quantum cryptography. However, the picture of the pendulum that represents the superposition of states is a bit misleading. Superposition means that the qubit can be in both quantum states at the same time. It doesn't meant that it is oscillating between the states. Hence, the movement or speed of the particles that you mentioned is not the reason why quantum computers perform calculations much faster than classical computers. Instead, it's the parallel computation which is possible due to the superposition of states that makes fast calculations possible because operations act on both states at the same time. A good example for this is the travelling salesman problem. A classical computer needs to try each possible way one after the other in order to find the shortest one, a quantum computer calculates all possible ways at once.

All this "tech advancement" yet the best thing consumers see is a newly upgraded phone every year. They've had advanced tech for decades, you think any of us will see it? The only thing that trickles down to us is "advanced entertainment". Don't forget about all the engineers who misteriously die after breakthroughs that would free the world eg Stan Myer.

Actually using your own analogy that means set quantum computers eventually will replace cars at least in most instances. You see bikes are becoming electric bikes and in ten years the average electric bike will easily be able to go 100 miles distance on a single charge and go about 25 to 30 miles an hour especially as normal vehicles die out. I mean currently there are electric bikes that can go over 100 miles distance and go up to 40 miles an hour. Granted 40 miles an hour is a little too fast at least until airbags for a person become more common.
You know about the helmets that look like a neck thing and then they become a helmet whenever you crash or the ones that envelop your entire body. Yeah once those become common enough been 40-50 miles an hour would be reasonable. However yeah basically normal cars are going to die out and electric bikes are going to replace them in the vast majority of instances

Fascinating and a little bit scary
but like the Firesign theater says

it’s a tool that can only be used for only good or evil

Ha!!
