Intel is working on the next step in MicroProcessors by building Quantum Circuits out of Silicon.

Intel breakthrough brings quantum computers a step closer to reality

Quantum computing harnesses the strange ability of subatomic particles Existing chips rely on superconductive materials and sub-zero temperatures Intel's new device is a move closer to quantum chips that work in the real-world Spin qubits are like semiconductor electronics and transistors as we know them Powerful computers capable of mind-boggling calculations have moved 'a step closer' to reality, thanks to a breakthrough at Intel.

 From article, (Powerful computers capable of mind-boggling calculations have moved 'a step closer' to reality, thanks to a breakthrough at Intel.
The technology firm has created a programmable quantum processor made with silicon, the same material used in conventional chips.
Previous developments in quantum computing have relied on special superconductive materials that work in near absolute-zero temperatures - making them difficult to create.
Intel's new device is a move closer to the creation of quantum chips that work in real-world conditions.
It could also pave the way for machines that are completely impenetrable to hackers using conventional methods of attack. 

Intel's new device is a move closer to the creation of quantum chips that work in real-world conditions.\



Intel created the prototype device with the help of Dutch firm QuTech, based at Delft University of Technology.

Quantum computing promises to harness the strange ability of subatomic particles to exist in more than one state at a time. 

This could allow them to solve problems that are too complex or time-consuming for existing computers, from modelling climate change to curing cancer. 

The team used microwave energy to alter the alignment of two electron particles suspended in silicon.

This let them programme two simple quantum algorithms. 
While this is considerably less powerful than other systems already in existence, if it can be scaled up quantum computers would be more easy to control and manufacture.
Quantum processors operate using qubits, which can store information in binary code – as a 0, a 1, or an arbitrary combination of 0 and 1 at the same time.
Among the challenges researchers must overcome before quantum computing can become a commercial reality is the incredibly fragile nature of these qubits. 
They deliver their quantum power by leveraging the spin of a single electron on a silicon device and controlling the movement with tiny, microwave pulses. 
Spin qubits are much smaller in size and the amount of time they can store information is expected to be longer than rival approaches. 
That gives them an advantage as researchers aim to scale quantum computing systems to the millions of qubits that will be required for a commercial system.   
They can also operate at higher temperatures, up to 50 times warmer than superconducting qubits. 


Intel has incorporated the spin qubits on its 300 mm process technology using isotopically pure wafers sourced specifically for the production of spin-qubit test chips. 
Fabricated in the same facility as Intel’s advanced transistor technologies, Intel is now testing the initial wafers.
Within a couple of months, the company expects to be producing many wafers per week, each with thousands of small qubit arrays. 
QuTech will announce their full findings at the American Association for the Advancement of Science (AAAS) Annual Meeting, being held from February 15 to 19 in Austin, Texas. 
They have also been published in a paper in the journal Nature.)

Me, "I compared this to the First Intel Transistors Way back in the 197os. Even the 4004, which had 2,300 transistors on it, is still too Late an example to use. 
This announcement is about maybe a few qubits here on silicon. 
It took 10-20 years until MicroProcessor PC's took off. So, this announcement means it could still be a long time before the general public sees Quantum Silicon Processor PCs. But, hey, progress today is much faster then the 70s' and 80's. There is a lot more money being invested in this field, so, we could see Quantum computers much faster."
