Philosopher Jill North explores quantum reality<\/a><\/h2>\n

Jill North, associate professor of philosophy at Cornell University, in a recent essay<\/a>1<\/sup> proposes that the wave function of quantum mechanics [\u201cthe mathematical object that represents the state system at a time\u201d] is real and fundamental, but occupies a space very different from the 3-D one we appear to live in. Although, we infer the fundamental nature of a world from the dynamical laws, we do not directly observe the fundamental level of reality of states themselves. We infer it from the dynamics of physical objects in the 3-D world.<\/p>\n

\u201cA match in structure between the dynamical laws and the world is evidence that we have inferred the correct space-time structure to a world governed by those laws,\u201d writes North.<\/p>\n

Ordinary 3-D space is not just an illusion, it exists, it is just not fundamental. It is an appearance of a deeper reality. Just as ordinary objects such as tables and chairs are not fundamental, but made up of more fundamental stuff, 3_D space is not fundamental, but is made up of the higher dimensional space of quantum states.<\/p>\n

Quantum Computers<\/h2>\n

Quantum computers can solve \u201cthe travelling salesperson\u201d problem<\/a> thousands of times faster than conventional computers, because operating with quantum states they can test the outcome of selecting many competing paths very fast.<\/p>\n
