Quantum computing takes a quantum leap towards reality

leave a comment »

An entangled state of six photons can form a quantum bit that is highly resistant to noise...

Speedy quantum computing communication takes a quantum leap towards reality.

I have discussed it before: all tech and thus change is accelerated by a version of Moore’s law which is to say some sort of exponential function. Sometimes individual tech gets a boost and does a quantum leap; which fuels the general evolution of other tech.

The problem so far has been that quantum mechanical laws says that just observing a system changes it’s state, and thus a computation is influenced by the computation itself. These things have been resolved, but what was missing, was to make sure that stimuli such as electromagnetic fields would not change the state of the machine.

A group in Stockholm has come up with a solution – click on the picture for the story itself.

Why is quantum computing important? Because they are extremely efficient calculators, tapping into fundamental physics AND adds probabilistic computing power. Whereas current computers are based on transistors and binary answers represented by bits (1 – 0), quantum computers are based on qubits which is basically native vectorized computation.
At the same time the fundamental building block of quantum mechanics is probability – not finite answers. So, a quantum computer will be efficient in solving statistical and probability problems.
Since most real life science heavily relies on modeling reality – a reality where no formula exists, but only an answer from trial and error with coupled differential equations that needs to be calculated with numbers – the promise is that we can solve such models much much faster.
And that’s great news for bio-science (genetics), aerospace, nano-tech, …, engineering where it is impossible to make a formula, but where you need to build a complex set of interconnected differential equations.

This computing power is one of the building blocks we are missing to be able to take quantum leaps in battery technology, gene therapy and many other promising future technologies.

Photovoltaics follow Moore’s Law

with 3 comments

Photovoltaic module price per watt, 2006 dollars

Photovoltaics follow Moore’s Law from David Leppik.

Most things – not just technology – follow a version 2 of Moore’s law, which is to say that advancement happens with a compounded rate, for example the number series that children like: 2+2 = 4, 4+4=8, 8+8 = 16 … 32, 64, 128, … plot this and you will see a rapid growth curve.

The same is  true for photovoltaic solar panels, the ones that convert the rays of the sun to electric energy, mostly due to advancements in nano-technology.

In 2008, David Leppik argued with his data analysis that the $1 mark will not be reached until post 2020. Moore’s law surprised us and in 2009, the mark was reached (note how progress went the wrong way from 2004 to 2008 in the graph). A quantum leap happened in 2009: “First Solar Passes $1 Per Watt Industry Milestone”

This is important for the future of the world, because there is a tipping point when oil is no longer relevant: the day that the price per watt from oil is more expensive than a convenient substitute. And that happens at about $1. The dream of fusion power is already real: it just happens to be a real big fusion power plant called the sun, that is the reality. Our job is to tap the radiation it sends our way, smiling at us.

The first change is to connect solar photovoltaic power to the utility network grid. That has happened on experimental ways for a long time now. Ones it is a feasible technology, political change won’t be that hard to imagine: after all, who really thinks it is very smart to be dependent on far-away countries ruled by … not so democratic leaders.

Energy is THE source of our productivity. Without it, everything comes to a grinding halt immediately. And with cheaper energy comes revolution.

It will be in our lifetime that energy is no longer a cost nor an environmental issue. It will bring about changes that we cannot imagine; because the cost per watt, with Moore’s law in mind, all things considered will go towards zero, since the sun is an eternal energy source (OK the sun explodes in about 5 million years and becomes a giant red star, but hey, don’t worry). The energy density of the suns rays are so powerful that with existing technology today, the efficiency is min. 20% of incoming energy to electric energy in solar panels. If the Sahara desert was converted to one big solar power plant, it would be capable of powering the worlds TOTAL energy consumption 18 times (barrels of petroleum, cubic meters of natural gas, watts of hydro power, etc.).

Think industrial revolution. It was all about tapping into coal via steam, which made chemical power into mechanical power for cheap. The revolution was not only one which created wealth, higher standard of living – but it also sparked a political revolution, which eventually got rid of feudalism and archaic aristocratic rule. Finally it empowered the building of new tools and technologies, which again gave rise to new technologies, which again… 2+2 = 4, 4+4=8 …

We are at a very very important tipping point.

The next major advancement needed to substitute our existing energy sources with solar power, is battery technology. I will write about that later on, but for now please note a couple of keywords: Ford is producing electric vehicles aggressively, Audi, Toyota, Mitsubishi, Daimler are equally doing just that. Obama is subsidizing battery technology startups and corporate programs aggressively as part of stimulus plan. Part of his plan is that America shall be the leading nation on all things solar in the future.

IBM’s 35 atoms, the rise of nanotech, Synthetic brains and solar power

with 2 comments

35 Atoms manipulated

35 Atoms manipulated

Maybe we should redefine Moore’s law a bit, and think technological progress as a something that may well jump in huge quantum leaps.

Moving 35 atoms, and the subsequent 20 years of research in nanotech is one of them, with implications that are so profound that we can hardly grasp them.

I am sure nanotech will enable neuro science to achieve a milestone called a 1:1 copy of the human brain (The Guardian, http://tinyurl.com/l6x4lh). The impact will be a liberation of the work force to be substitute with “tools”, at this time with some resonances to Blade runner (if its a brain, it feels and thinks. Does it then have rights?)

It is not the first time the work force has been liberated.

The last time it happened, with the steam engine, it replaced feudalism with its industrial revolution. The “above the law class” of aristocrats went out of power. Production boosted exponentially, life expectancy boosted and a new political system was invented, granting more freedom to its people – first with the American civil war and French revolutions.

The liberation of the work force has always happened by technological advancement. Think the wheel, the plow and add the steam engine. In this way, the Internet and IT has already done its share of liberating the work force and changing democracy thru the last 20 years.

Imagine that the machine no longer requires humans.

However, the major changes are tied to the cost of energy. The plow optimized production because it tapped into an energy source which was not yet exploited: that of cows, horses, donkeys. The steam engine tapped into coal and converted it to mechanical energy.

The next major change of our world will happen when probably nanotech solves – in a quantum leap – the problems of battery technology and photo voltaic solar panels: how to make batteries smaller, cheaper and lasting longer. How to make solar panels cheaper and catching more energy (http://en.wikipedia.org/wiki/Solar_cell nad http://en.wikipedia.org/wiki/Solar_energy).

These black dots could power the worlds energy need today with photovoltaic solar power

These black dots could power the worlds energy need today with photovoltaic solar power

All things considered, in the next twenty years, we will see a substitution of photovoltaic energy with oil. In a hundred years, I will bet you its a complete substitution.

The important point in that is: electric energy – energy – will move towards a price which is zero.

Once that happens – and energy is efficiently stored in batteries incl. fuel cells – you can waive bye bye the to world as you know it.

The future is silent

leave a comment »

A Mercedes S400 Hybrid was driving past me, while I was sitting at a café. Silent. And it made me think about the silent future.

Battery technology follows Moore’s law: at a rapid pace they are getting smaller, getting more ampere to last longer and taking shorter time to charge. This will give cars with longer range, going towards what a tank of gas gives you. That is, with the same performance.

As oil will continue to go north in pricing and electricity, for many reasons, will continue to become cheaper, electric cars will be the majority of the fleet in say 8 – 10 years: Particularly because politicians will push for it, as it is seen in California and with stimulus packages to Detroit for battery tech programs both in startups and in corporates.

The future is silent.
