Opinion: Some months ago, I introduced the idea of quantum computing in this column

Posted by in categories: quantum physics, robotics/AI, transportation

All of today’s computing takes its root from the world of “bits”, where a transistor bit, which lies at the heart of any computing chip, can only be in one of two electrical states: on or off. When on, the bit takes on a value of “1” and when off, it takes on a value of “0”, constraining the bit to only one of two (binary) values. All tasks performed by a computer-like device, whether a simple calculator or a sophisticated computer, are constrained by this binary rule.

Eight bits make up what is called a “byte”. Today, our computing is based on increasing the number of bytes into kilobytes, megabytes, gigabytes and so on. All computing advances we have had thus far, including artificially intelligent programmes, and driverless cars are ultimately reduced to the binary world of the bit.

This is a natural extension of western thought; for centuries, western philosophy has followed the principles of Aristotelian logic, which is based on the law of identity (A is A), the law of contradiction (A is not non-A), and the law of the excluded middle (A cannot be both A and non-A at the same time, just as non-A cannot be both non-A and A at the same time).

Quantum Computing Can Reshape Our Physical Infrastructure If We Let It

Posted by in categories: information science, quantum physics, robotics/AI, transportation

Despite growing excitement around the transformative potential of quantum computing, leaders in many industries are still unfamiliar with the technology that’s likely to prove more disruptive than Artificial Intelligence and blockchain. This ignorance seems particularly acute in industries that deal with physical systems and commodities. In an informal survey of two dozen executives in transportation, logistics, construction and energy, only eight had heard of quantum computing and only two could explain how it works.

In many ways this lack of awareness is understandable. Quantum computing’s value to our digital infrastructure is obvious, but its value to our physical infrastructure is perhaps less evident. Yet, the explosion of power and speed that quantum computers will unleash could indeed have a profound impact on physical systems like our transportation and utility networks. For companies, municipalities and nation states to stay competitive and capture the full benefit of the quantum revolution, leaders must start thinking about how quantum computing can improve our infrastructure.

Unlike classical computers, in which a bit of information can be either a zero or a one, quantum computers are able to take advantage of a third state through a phenomenon known as superposition. Superposition, which is a property of physics at the quantum scale, allows a quantum bit or qubit to be a zero, a one or a zero and a one simultaneously. The result is an astronomical increase in computational capacity over existing transistor-based hardware. Google, for example, has found that its quantum machines can run some algorithms 100 million times faster than conventional processors.
