Just to clarify an important point: People are playing with words when they use "quantum" to describe their new chips. It's not that hard to build a processor using 128 atoms to perform useful calculations.
A "real" quantum computer requires every qubit in the system to be entangled with all of the other qubits. It is from this entanglement property that quantum computers experience a significant speed-up compared to classical computers. Without entanglement, you're left with a computer that plays in the same ball park as your ipad. Creating and maintaining this entanglement is highly unstable. Systems tend to break down very quickly as you add qubits. It is even debated whether entanglement is physically possible to maintain for any significant number of qubits.
To date, I believe we have only been able to factor 3x5=15 with 7 qubits and more recently 11x13=143 on 4 qubits. However, for the second result, it is debated whether entanglement actually occurred.
So don't worry about these silly claim
Hope this clarifies it a bit!
Edit: Okay it's pretty clear everyone thinks this is fake ! I'll leave my post for info
