Quantum computing is a new field
that combines ideas from computer science and quantum physics to
investigate the design and capabilities of hypothetical computing
devices that harness delicate quantum effects in the service of
computation. By clever utilization of the properties of superposition
and entanglement, a new form of "quantum parallelism" appears
achievable, wherein an exponential number of computational paths can be
explored "at once" in a single device. The challenge is to frame
computational questions in such as way as to extract a useful,
typically probabilistic, answer.
In addition to improved
computation, quantum theory allows enhanced precision in certain
classes of measurements. Examples of these are the quantum gyroscope,
quantum lithography, clock synchronisation and frequency measurements.
The principle of quantum lithography allows light to beat the Rayleigh
diffraction limit, and as a consequence it can be used to create
smaller patterns on microchips without resorting to smaller
wavelengths.
