quotes about quantum computing made in Finnish TV news watched by ~1.5 million people:The commenter thinks that this is a distortion, but how would any non-physicist think anything else?
“Qubits are the quantum computing equivalent of normal computers bits, which are ones and zeros. Unlike a bit, qubit is not just one or zero, instead it can be both one and zero at the same time.”
“-This is a device that makes the impossible possible. Even if all supercomputers of the world would do something together for years, they could not solve things that quantum computer will at some point solve in a snap of fingers.”
“-Here we are learning how to build a quantum computer, learn to develop different parts, learn to write software and to apply them for different tasks. The real benefits will certainly come in the next phases at the end of 2020’s.”
The context of this was the announcement of 20 million euro funding to build Finland’s first quantum computer.
In quantum mechanics, Schrödinger's cat is a thought experiment that illustrates an apparent paradox of quantum superposition. In the thought experiment, a hypothetical cat may be considered simultaneously both alive and dead as a result of being linked to a random subatomic event that may or may not occur.So a cat can be alive and dead at the same time. If you believe that, then a qubit can be one and zero at the same time.
If you think this is nutty, and I do, then get the Physics popularizers to stop saying that a cat can be simultaneously alive and dead.
The story also over-hypes what quantum computers will do for us, but again, it is just parroting what physicists say. In June 2019 I noted that experts were saying that quantum computing capabilities were growing doubly exponentially. If that were really true, then quantum computers would be doing useful things by now. But that could be decades away, or never happen.
