Quantum Computer Reviewed

Back in the 80's, quantum computing was viewed as something of a futuristic scenario, something out of a sci-fi flick like Minority Report. However, in 1994, interest ameliorated immediately after Peter Shor, then at Bell Laboratories (now at MIT), published his famous quantum factoring algorithm capable of undermining widely used cryptosystems that relied on the difficulty of factoring large numbers.

Currently, there are physicists, computer sciencists, and engineers in more than 100 groups in universities, institutes, and companies around the world are exploring the frontiers of quantum information, encompassing quantum computing, as well as recently commercialized quantum cryptography and quantum teleportation communication techniques.

Ross and Oskin's Quantum Computing is definitely worth a read. Exponentially scalable computing power that could solve problems beyond the capabilities of conventional computers. The key is exploiting the superposition of quantum-entangled information units, or qubits. But the research challenges are daunting: How to create and reliably compute with the qubits, which require the seemingly mutually exclusive conditions of exquisite classical control while being isolated from any external influences that could destroy the entanglement.

What does this mean for information professionals? A lot. With Web 3.0 around the corner, information processing at high levels will be necessary. It's still cloudy as to how it will all look like. But with quantum computing, we're on the right track.
