Short and simple: yes. Though the question is how relevant this is. Likely SSH will have moved to something more secure years before any quantum computer with sufficient computing power will become available. Because that's the thing these scare-stories don't tell you: While the progress in quantum computing is moving very slowly, in recent years the progress in post quantum cryptography has been very fast.
A quantum computer with threatinging amounts of qubits could already exist as a secret military project today.
I assume you are correct. I also assume you and I are somewhat safe. You have to consider the likely hood of an individual getting a hold of one of these devices in the near future. Then again you really have to ask if there is any reason you in particular will be targeted by someone with this technology.
Eventually everyone will be targeted. I have an unannounced web server serving a domain in the middle of internet nowhere and I get script attacks all the time. If some how this gets commercialized with no regulation criminals will open up shop for business practically the day after. Its like CRISPR: sure it can do some powerful things but so can your adversaries to you. I hate to think of the internet as a cloud of…
CRISPR fears are really overrated. It is nowhere near as mature as it needs to be. Further, you're less likely to make anything useful with it and more likely to just kill the organism you are trying to create. I work in a biotech lab, and we hardly ever use it and instead opt for manual plasmid knock in/down or tissue engineering techniques instead. The extent of work you have to put in to actually get something useful from CRISPER is prohibitive of it being used to target you and I.
You can't make statements like that without elaborating on what quantum computing can possibly provide.
Two examples off the top of my head: 1. Instantaneous stock transactions from anywhere in the world. (quantum communication/entanglement) Offers a substantial RTT improvement on current trading systems. 2. High frequency trading based on quantum prediction algorithms. (Quantum information theory) May provide for HFT algorithms capable of producing predictions based on an exponential number of information streams. E.g…
