In the Quantum Era, TV Images Get Sharper and Password Hacking Becomes Impossible [Watching a Science YouTube Channel]

According to The Financial News, quantum technology has recently been emerging in the scientific community, and experts predict that once the quantum era fully arrives, video images on devices such as TVs will become extremely sharp and password hacking itself will become impossible.
On the 27th, the science YouTube channel "Gwajangchang (The Moment Your Science Knowledge Shatters)" explained that, unlike conventional technologies, quantum technology operates in an irregular and simultaneous manner. Because of this, it can work far faster and more efficiently than existing methods, and it is expected to bring groundbreaking changes to everyday life.
One example is quantum dot technology, which uses extremely small nanoparticles. This technology can adjust light with great precision at a very fine scale. At the same time, it consumes relatively little energy, making it highly energy-efficient. Experts note that this can be applied to high-definition TVs. When quantum dots are used, TV picture quality becomes extremely vivid and clear, because the particles themselves emit light.
Another example is quantum random numbers, which can block hacking at its source. Conventional random numbers used to create passwords only appear random, so in practice they can be hacked. Even if the rules are complex, there is still an underlying pattern that can be predicted. In contrast, quantum random numbers are composed of values that are fundamentally impossible to predict. They arise from physical phenomena and form truly irregular random sequences, unlike conventional random numbers whose patterns can be uncovered due to software limitations. In particular, with quantum key distribution (QKD), if someone attempts to eavesdrop on or intercept the key, it is immediately discarded. As soon as there is any trace that the quantum key has been exposed, the number itself is invalidated, allowing security to be maintained continuously.
Meanwhile, quantum computers are described as being incomparably faster than conventional computers. Traditional computers rapidly process calculations based on the binary digits 0 and 1, whereas quantum computers use quantum states in which 0 and 1 are superposed. This allows them to evaluate many possible answers to a problem at the same time and derive a solution much more quickly.
