Quantum Computer Invented

[beekeeper]

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"
Not much of quantum computing yet..

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
