The next in our Quantum CEO series looks at the nature of a fundamental element of quantum computing – the qubit. Dr. Theau Peronnin, cofounder and CEO of Alice & Bob, joins host Eric Hanselman to explore the nature and characteristics of this often-misunderstood foundation of the quantum world. There is no standardized definition for a qubit, and yet, many quantum efforts measure their success in terms of qubit counts. At the same time, there are efforts to define logical qubits, as a more functional measure, further clouding the term. It's far better to look at the work that they can do and what the constraints are in their operation. The current generation of quantum computers work with environments that are computationally noisy, creating error rates that are more than eighteen orders of magnitude greater than classical computers. That puts a focus not only on managing error rates, but also on establishing meaningful benchmarks around quantum performance.
There are also efforts to expand the working life of a qubit, the coherence time, and the speed of computation. Differing approaches to quantum computing trade off stability and durability of the quantum state needed to perform a computation. Quantum capabilities are expanding more rapidly than many had predicted and organizations need to develop a better understanding of where and when quantum computing can fit in their business plans.
