Plasmanu only has to dismantle the BMS, understand how it works with the scooter, by hacking the code of the microprocessors, then rebuild it suitable for a battery !!


Otherwise, read the detailed scientific description of Dwave to get a good idea of ​​the beast:
http://www.dwavesys.com/sites/default/f ... _0915F.pdf

http://www.nature.com/nature/journal/v4 ... 10012.html


Otherwise you will find many denigrations of this simplified solution, by those who missed this idea!

Our world is quantum, anything, a magnet, a superconductor, glass, is a quantum computer, but uncontrollable, because then if we want to control, too much the variables, decohedral quantum (destructive interference passing from wave wave to conventional optical rays, for example).
Dwave chose to control only part of a specific but general problem !!
To control demands very low temperatures !!

QUANTIC COMPUTER: A NEW MICROPROCESSOR OPERATES ON 4 QUBITS AT A TIME

Researchers have designed a 4-bit quantum silicon circuit that performs the function of an information and short-term memory "mixer". And this basic building block of the quantum computer can be mass-produced!


We tire of repeating that the basic elements of the quantum computer, a dream machine surpassing any conventional computer, are ready: we manage to materialize the "qubits" (quantum bits) by atoms, ions or superconducting loops, we also know how to build logic-quantum gates for operations with these qubits ...

But the most difficult thing remains to be done: increase the number of qubits involved in the operations. But a team of German researchers has developed a microprocessor technology, producible in series, which can trap and operate on 4 qubits at a time. Unveiled in the journal Physical Review Letters, it is one more step towards the realization of the machine.

The "qubit" and its exponential explosion

Among the arguments extolling the quantum computer, one evokes the possibility of encoding and processing a large quantity of information in a single "operation", by relying on two strange quantum phenomena: the "superposition of states" and the '"entanglement".

The basic element is the qubit. In conventional computing, the bit is a physical entity (voltage V) that encodes a single piece of information, "0" (V-) or "1" (V +). But a qubit can simultaneously encode the two pieces of information "0" and "1" ...

Similarly, if two conventional bits only encode one piece of information, for example "00" or "01" or "10" or "11", a system of two qubits can encode all four possibilities simultaneously. More generally, a chain of N qubits can encode 2N values ​​simultaneously. We are talking about an exponential explosion ...

Yes you read that right ... 600 million years ... and quantum supremacy reached! (I don't know what it is anymore but it looks neat! : Mrgreen: )

Well done Google, there is little more than the GAFAs that make people dream today! 1000 Qubits! It's going to happen a lot faster than I expected. Advances in physics now pass extremely quickly in engineering and practical applications, especially in the United States where universities have deals with industry. Will they have the AI ​​that is doing well to counter the Great Reset soon enough ?!

However, IBM researchers subsequently disputed these results, arguing that the computation submitted to Sycamore would have been performed by IBM's Summit supercomputer in 2 days; “supremacy” was therefore called into question.
And for the Chinese boson sampling
While this is an impressive achievement, quantum supremacy only means that this device is better than conventional computers at an extremely specific task. “It doesn't mean building an evolutionary quantum computer, or a universal quantum computer, or a useful quantum computer,” says Aaronson.

Not at all.
Who has the power?
On the one hand, multinationals, basing their investments on possible returns. Of course, money is their motivation, but investments are also high risk bets and I see them quite playful: space tourism or the quantum computer, no one knows if it will be achievable, profitable, or when. They are betting on the future and innovation, I see that as extremely positive.
On the other hand, politicians, basing their power (in a democracy, I don't even speak of Russia, China or North Korea) on their ability to handle the herd (the people), their subservience to lobbies and the feedback they may have of whether these lobbies are multinationals or political movements such as environmentalists, and their party ideology. I don't really see what they have to offer. The less competent always want to regiment the world that others make, failing to know how to build it. Wielding fear is their favorite weapon.
I still prefer the former, the latter not even serving today to moderate the excesses of the former.

... And for the Chinese boson sampling

The future will tell what is the most efficient way to implement quantum computing. There is not a single physical process, it is a question of technology, quantum mechanics being only the solid theory which shows that it is possible.

Amazon would work on its first quantum computer https://www.journaldugeek.com/2020/12/0 ... quantique/

Honeywell's System Model H1 is a quantum computer with 10 fully connected qubits and a quantum volume of 128. https://www.generation-nt.com/ordinateu ... rformances.
US tech company Honeywell announced last week the introduction of its next-generation quantum computer. The System Model H1 is based on the trapped ion technique with a QCDD (quantum charge-coupled device) architecture.

Such an architecture takes advantage of ytterbium ions for calculations, combined with barium ions for cooling. To get started, the System Model H1 offers 10 so-called fully connected qubits. According to Honeywell, it is possible to achieve a quantum volume of 128.

In the race for quantum volume
Such a measure of quantum volume - dear to IBM - is an indicator of the overall power for quantum computing which does not only take into account the number of physical qubits, but elements such as the number and precisely the connectivity of the qubits, the rate of errors.

With a quantum volume of 128, Honeywell claims the highest measurement in the industry, knowing that last August, IBM reached a quantum volume of 64 (with a 27-qubit system) as part of its annual doubling of performance.
Over the next ten years, Honeywell aims to go from 10 qubits to 40 qubits with a System Model H5 in 2030, while increasing the quantum volume each year.
