Commonly-made statements such as the one above illustrate the concerns of privacy advocates with quantum computers. While the statement is almost certainly true, it also is an example of doomsday prediction<ref>http://rationalwiki.org/wiki/Prediction</ref> and fatalism; concepts that Psychology seeks to research.
Quantum computers are intended to perform operations on data using the phenomena of quantum mechanics (also known as quantum physics, or quantum theory). While the state of a digital binary "bit" is expressed in discrete values of 0 or 1, the qubit of quantum computing is more complex. The value of a qubit must be expressed as a continuously-valued<ref>https://en.wikipedia.org/wiki/Quantum_information_theory</ref> direction on a "Bloch sphere", calculated by the superposing (adding together) of its two basis states<ref>https://en.wikipedia.org/wiki/Two-level_system</ref>, referring to the "physically distinguishable" states observeable by quantum mechanics.
Public interest in quantum computing is recent (when?), although professional interest in and research of quantum computing dates back to 1981<ref>https://en.wikipedia.org/wiki/Timeline_of_quantum_computing</ref>. Although currently promising, the proper design and eventual construction of quantum computing devices is still theoretical, despite claims and predictions of their absolute creation. Extensive progress is demanded for quantum computing, thanks to the strong incentives for multiple players and the research fertility of Quantum mechanics. According to Wikipedia, "Google has announced that it expects to achieve quantum supremacy by the end of 2017<ref>https://en.wikipedia.org/wiki/Quantum_supremacy</ref>."
Attempts to better understand the mechanisms behind quantum theory have been met with (for lack of a better word) resistance. Quantum theories are counter-intuitive, and quantum phenomena have been found to operate in a completely different manner than Newtonian physics. Should quantum computing ever become a reality, the unpredictability of Quantum mechanics could lead to unforeseen results in the future.
