this is the human vs robot table tennis videofrustating slo mo and camera work makes it look staged and not reali was hoping for a man vs machine sporting event.the guy wasnt playing at all like he would be playing against and actual opponent.
Quantum ComputationRather than store information as 0s or 1s as conventional computers do, a quantum computer uses qubits – which can be a 1 or a 0 or both at the same time. This “quantum superposition”, along with the quantum effects of entanglement and quantum tunnelling, enable quantum computers to consider and manipulate all combinations of bits simultaneously, making quantum computation powerful and fast. How D-Wave Systems WorkQuantum computing uses an entirely different approach than classical computing. A useful analogy is to think of a landscape with mountains and valleys.Solving optimization problems can be thought of as trying to find the lowest point on this landscape. Every possible solution is mapped to coordinates on the landscape, and the altitude of the landscape is the “energy’” or “cost” of the solution at that point. The aim is to find the lowest point on the map and read the coordinates, as this gives the lowest energy, or optimal solution to the problem.Classical computers running classical algorithms can only "walk over this landscape". Quantum computers can tunnel through the landscape making it faster to find the lowest point. The D-Wave processor considers all the possibilities simultaneously to determine the lowest energy required to form those relationships. The computer returns many very good answers in a short amount of time - 10,000 answers in one second. This gives the user not only the optimal solution or a single answer, but also other alternatives to choose from.D-Wave systems use "quantum annealing" to solve problems. Quantum annealing “tunes” qubits from their superposition state to a classical state to return the set of answers scored to show the best solution.
i don't pretend to understand the science here, but the Time article i read compared the function of a quantum computer to the human brain and i thought that sounded neat.http://www.dwavesys.com/QuoteQuantum ComputationRather than store information as 0s or 1s as conventional computers do, a quantum computer uses qubits – which can be a 1 or a 0 or both at the same time.

As far as I can tell, the "quantum" in quantum computing is, at best, just a metaphor.

oh yeah, wireless charging is just a novelty, @pissclams. http://www.salon.com/2013/08/17/electric_roads_to_the_hyperloop_our_jetsons_future_starts_now/
I'm looking forward to the day when our washers & dryers fold and put away our clothes for us!

Like, what a rough ridin' nerd. Yeah, the second our cars drive themselves everything will be utopian as crap. Yep, that sounds about right.

plus the guy writes like someone I'd like to punch in the gut
And here you find civilized man. Civilized man refused to adapt himself to his environment. Instead he adapted his environment to suit him. So he built cities, roads, vehicles, machinery. And he put up power lines to run his labour-saving devices. But he didn't know when to stop. The more he improved his surroundings to make life easier... ...the more complicated he made it. Now his children are sentenced to to years of school, to learn... ...how to survive in this complex and hazardous habitat. And civilized man, who refused to adapt to his surroundings... ...now finds he has to adapt and re-adapt... ...every hour of the day to his self-created environment.
