Reading the article this sounds more like a quantum scale Turing computer building block rather than an actual quantum computer building block. I mean they were only able to achieve two states, 0 and 1. Or did I misunderstand something?
It's rather "Successfully interfacing a qubit using regular ASICs" Smiley
Not much of quantum computing yet..

Each block is stacked on top of the previous one. Adding another block to the top makes all lower blocks more difficult to remove: there is more "weight" above each block. A transaction in a block 6 blocks deep (6 confirmations) will be very difficult to remove.

The power of qbits is when they interact with each others, IMO reading a single qbit with a regular transistor is similar to reading 4 bit from a NAND cell.

They've had single qubit quantum "computers" for a decade. The trick is scaling it up to the necessary number of qubits to make it useful.

What's new here is that the quantum behaviour has been implanted into a silicon transistor.

Death of Bitcoin?

No.
Lots of threads on this. Here's a recent one: https://bitcointalk.org/index.php?topic=105756.0
Bitcoin is the first monetary system to credibly offer perfect information to all economic participants.
