The biggest threat to data security in quantum computing is other quantum computers.
Is quantum computer unbreakable against hackers? The thing is that nothing lasts forever. And the biggest threat to data security in quantum computing is other quantum computers. But there can be possible to observe qubits by using small-size devices that are observing the size of quantum fields of the quantum computer. One version is to superposition the atom in the quantum system, and that thing is used as an antenna that is observing the annealing of the quantum system.
When we are talking about pocket-size quantum computers, we forget one thing. Most quantum computers need extremely low temperatures that they can operate. So even if the quantum computer itself is small-size the cooling elements around it can be extremely large. The thing is that the quantum computer is the ultimate tool for data security. But when they are turning more common.
The security algorithms and protocols that are made by using quantum computers can be dangered. One version of how to hack the quantum computer is to install the radio sensor in that cooling system, that records the electromagnetic fields of qubits. Also, the spying tool can be the nanomachine or extremely small-size robot that resends the information to the larger computers that can try to break the secured processes.
And those systems can use quantum annealing in that process. The system observes the changes in the brightness of qubits, and then that data can analyze by using the other quantum computer.
If we are thinking of quantum computers as unbreakable systems, we must remember that the same thing has been said about RSA encryption. That encryption bases on the two keys public (Username) and encrypted key (Password). That algorithm should be unbreakable, but it has been broken a long time ago. The reason why that thing has happened is the increasing power of computers. Of course, breaking the encryption code is turned more difficult by including special marks. And making the passphrase unlimited. But the historical eight-mark passphrases are quite easy to break.
Especially if the passphrases are including only letters and numbers. And history is repeating itself in quantum computers. We know that someday the quantum computers are hacked. There is one thing that can open the secrecy, that is made by using quantum computers. And that thing is another quantum computer.
The biggest threat is that the next-generation quantum computer will break the code that is made by using elder quantum computers. The fast advantage in quantum computer technology is causing the threat that the algorithms that are made by using old quantum computers turn too light for securing the data.
When data is traveling in the quantum channel it should be invisible from outside. In that case, the qubit would be an electron, that travels in the laser ray. During that process, the electrons are interacting with the photons.
And if there is a spying tool in the same space as that quantum wire. There is the possibility to observe the changes in the brightness of the laser ray. And that data can be used in the code-breaking process. In some other visions, the particles will superposition and are entangled through the quantum wire. In that case, qubits are interacting with the quantum bridge. And that stress can use for uncovering the data that travels in the quantum wires.
