48000 x $70 = $3.36 Million a month x 12 = $40.32 Million a year.
The cell phones are probably closer to $40 a month in order to get
48000 x $40 = $1.92 Million a month x 12 = $23.04 Million a year which is closer to the $20M dollar savings the article talked about.
A quantum computer is a computer that uses at least one quantum effect to solve problems. Currently quantum computers are leveraging either superposition or entanglement. A difficult hurdle to scaling quantum computers is decoherence which basically renders qubits inoperable. Decoherence happens when qubits are too close to each other. This is a major problem because currently we scale processors by cramming more and more transistors into a smaller and smaller space.
There is no one-way to build quantum computers. Several models are Gate model, Adiabatic, Measurement Based, and Topological. Several implementations are Ion Trap, NMR schemes, Nitrogen Vacancy, and Superconducting electronics. Some of these such as Nitrogen Vacancy are theoretical at this point since nobody has figured out how to implement them yet.
Basically Quantum computers at this stage aren't envisioned to replace classical computers, but they will be really useful as specialized computers for solving certain types of problems. The problem with classical computers are that they work off of classical physics and so they have a hard time modeling the way the universe really works (ie in a quantum manner). Quantum computers on the other hand behave in a quantum manner (duh) and so they are more ideally suited to solving simulation type problems. Some problems they are ideally suited for are machine learning, pattern recognition, neural networks, and building synthetic brains.
IBM has a 7 qubit machine that can successfully factor the number 15. This is not very impressive computationally but it does serve as a working proof that quantum computers aren't just theory. She showed a picture of a chip that has 128 qubits on it and another picture of a quantum computer that takes up a full room. She predicts we will see a commercially viable quantum computer within the next few years.
Of course, right now the worldwide market is zero, since they haven't actually constructed one yet.
Except that in the video she clearly talks about several quantum computers that have been built and have actually solved problems.
