If multiple qubits are entangled meaning that their quantum states depend on each other then a single quantum computation is in some sense like performing many computations in parallel.
For that reason optical systems are a promising approach to quantum computation. But any quantum computer--say one whose qubits are trapped laser ions
or hundreds of photonic qubits it becomes unwieldy to do this using traditional optical components says Dirk Englund the Jamieson Career development Assistant professor in Electrical engineering and Computer science at MIT and corresponding author on the new paper.

#Computing: Common'data structure'revamped to work with multicore chips Today hardware manufacturers are making computer chips faster by giving them more cores
But while some data structures are adapted well to multicore computing others are not. In principle doubling the number of cores should double the efficiency of a computation.
With algorithms that use a common data structure called a priority queue that's been true for up to about eight cores
--but adding any more cores actually causes performance to plummet. At the Association for Computing Machinery's Symposium on Principles and Practice of Parallel Programming in February researchers from MIT's Computer science and Artificial intelligence Laboratory will describe a new way of implementing priority queues that lets them keep pace with the addition of new cores.
In simulations algorithms using their data structure continued to demonstrate performance improvement with the addition of new cores up to a total of 80 cores.
A priority queue is a data structure that as its name might suggest sequences data items according to priorities assigned them
Priority queues are central to the standard algorithms for finding the shortest path across a network
and computer science and one of the new paper's co-authors. All of these guys try to put the first element in their cache
their advisor professor of computer science and engineering Nir Shavit; and Microsoft Research's Dan Alistarh a former student of Shavit's relaxed the requirement that each core has to access the first item in the queue.
--which must be the case for multicore computing to work anyway--they can simply be assigned to cores at random.
But the MIT researchers'algorithm starts farther down the hierarchy; how far down depends on how many cores are trying to access the root list.
One such piece of evidence comes from an observation surrounding fetal programming, says Rosen.""Fetal programming centers on a person's exposure in utero,

When the researchers treated live bacteria with the new drug two of the genetic changes actually arose just as their algorithm predicted.
This gives us a window into the future to see what bacteria will do to evade drugs that we design before a drug is deployed said co-author Bruce Donald a professor of computer science and biochemistry at Duke.

allowing observation of computation as it occurs in real time. The presence or absence of a droplet represents the 1s and 0s of binary code
and the clock ensures that all the droplets move in perfect synchrony, and thus the system can run virtually forever without any errors."
