Ik heb de eerste link bekeken en er begint een licht te branden. Zeer belangrijke ontwikkeling idd. vooral als je bedenkt dat de huidige computers tegen hun grens aankomen.

Jammer dat het nog wel even zal duren voor de QC op ieders bureau staat. Hopelijk komt er in de tussentijd een ander soort computer, de lichtcomputer ofzo.

aha, jammer maar vraag anders of ze een update wil geven van wat er op dit gebied allemaal gebeurt in NL... en de eventule voortgang. Ik heb zo'n vermoede dat als je er niks mee te maken hebt er ook weinig van te weet komt over wat er nu zoal speelt op dit gebied...

Ja ik heb ook zoiets gehoord. Dat je met zo'n computer ongelooflijk goede encryptie kunt krijgen.

In the summer of 2002, I devoted some of my research effort to the problem of generating neural nets at the quantum scale. In 10 years or so, Moore's Law will take electronic circuitry down to the molecular scale, therefore the creation of neural nets will require the appropriate quantum computing algorithms. Since I have a theoretical physics background (I worked with the famous Prof. David Bohm (of Bohmian Mechanics fame)) I and my research assistants are now working on quantum algorithms applied to neural net creation. In fact, our group no longer speaks of neural net evolution, since evolutionary algorithms are only needed in a classical computing context, where a classical computer can only process one Nbit bitstring at a time. Since there are too many (2**N) possible chromosomes in the search space, only a sampled search can be undertaken, which is what an evolutionary algorithm is. BUT, with quantum algorithmic techniques, all 2**N chromoses can be processed at once, thus killing the need for evolutionary algorithms. Our group has discovered quantum algorithms that measure the fitness of all 2**N chromosomes (hence quantum neural networks) at once. Most quantum evolutionary computation approaches use a classical genetic algorithm and apply it to generate a sequence of quantum operators operating on a string of quantum bits (qubits), which is a form of classical/quantum hybrid. We use a fully quantum approach, and thus dont need an EA, since the whole 2**N point search space is explored simultaneously. Thus we speak of quantum optimization rather than quantum evolution. In this case, QC has made EC redundant. My prediction is that QC will largely kill off EC in the future. My opinions on this point are still evolving ;-)

A new breed of faster, more powerful computers based on quantum mechanics may be a step closer to reality, report scientists from Purdue and Duke universities.

Spy networks and international financial systems are set to benefit from a significant advance in teleportation technology developed at The Australian National University.
ANU researchers in Canberra have announced that they are the first in the world to demonstrate the sharing of secrets via teleportation using quantum physics. The research has potential to significantly enhance the security of computer systems around the world.

The researchers then demonstrated the use of the three-photon entangled state to make extremely precise measurements. To do so, they used an experiment based on a paradox associated with quantum mechanics, which suggests that a particle can be in two places at once.

By observing the movement of the photons past a series of mirrors and filters, the team was able to determine how far the photons had traveled.

Because the team used photons in a three-photon state, the system could provide measurements that were three times as precise as those made by a single photon. Since the new system, in theory, could incorporate an even larger number of photons, it could someday lead to a measurement system with significantly greater accuracy than anything that currently exists.
