IBM makes leap in quantum computing power

IBM has some new options for businesses wanting to experiment with quantum computing.

Quantum computers, when they become commercially available, are expected to vastly outperform conventional computers in a number of domains, including machine learning, cryptography and the optimization of business problems in the fields of logistics and risk analysis.

Where conventional computers deal in ones and zeros (bits) the processors in quantum computers use qubits, which can simultaneously hold the values one and zero. This — to grossly oversimplify — allows a quantum computer with a 5-qubit processor to perform a calculation for 32 different input values at the same time.

Look before you leap: 4 hard truths about IoT

Most technologies go through a stage when everything seems possible. Personal computers in the early 1980s, the internet in the late 1990s and mobile apps around the beginning of this decade were like that.

But so was the first unboxing of a Galaxy Note 7. In time, either suddenly or gradually, reality sets in.

The internet of things still looks promising, with vendors and analysts forecasting billions of connected devices that will solve all sorts of problems in homes and enterprises. But the seams are starting to show on this one, too. As promising as the technology is, it has some shortcomings. Here are a few.
