Quantum computing offers the promise of being the next big technological breakthrough. However, the many companies attempting to develop commercially viable quantum systems are pursuing a host of different technological approaches. While some of these may pan out, others may not. And while some could reach a useful level of accuracy soon, others may take considerably longer.<\/p>\n

Let’s look at four of the main quantum computing technologies and the companies pursuing them. <\/p>\n

1. The superconducting qubit approach<\/h2>\n

All quantum computers are built around qubits — their fundamental units for holding and processing information. But just how one goes about creating and manipulating those qubits is where the variation gets wide.<\/p>\n

One of the most common approaches being pursued uses superconducting qubits: electronic circuits made of superconducting materials that must be brought to temperatures near absolute zero, and that are controlled using microwave pulses. These circuits can be manufactured in traditional semiconductor fabs, and the qubits don’t require complex laser setups to hold them in place.<\/p>\n

The biggest strength of the technology is its gate speed, which is much faster than some of the other techniques being pursued. However, its fabricated qubits are more susceptible to being influenced by external forces, which leads to more errors in their calculations. They also require expensive dilution refrigerators to keep the entire system cooled to the temperatures where the qubits’ behavior is governed by quantum mechanical principles.<\/p>\n

Among the companies pursuing this technology are IBM<\/strong> (IBM 3.25%<\/span>)<\/span> and Rigetti Computing<\/strong> (RGTI 2.06%<\/span>)<\/span>. Rigetti has had documented issues with delays and accuracy, and seems further behind many of its peers in the race to deliver a useful system. While IBM’s systems also lag in fidelity measurements, it is taking some novel approaches to solving the error-correction problem, such as c-couplers and real-time error-correction decoders, that look…<\/p>\n
