The research portfolio now includes applications in nuclear and particle physics, plasma science, chemistry, and materials. It also includes improving the fundamental building blocks of quantum computers, developing sophisticated control to make the most of any group of qubits, and computer science research that will ultimately make quantum computers easier to use. IBM’s quantum computers are programmed using Qiskit, our open-source, Python-based quantum SDK.
Since the latter gate makes no difference to the output from the computation, it can safely be omitted. We’ll see examples in the next essay, about the quantum search algorithm, where at a couple of places it makes sense to multiply the quantum state by a global phase factor of −1-1−1. One reason is that, as we discussed earlier, humanity doesn’t yet know what the higher-level abstractions are. A second reason is that it seems likely that the list of higher-level abstractions is inexhaustible. My guess – and it’s just a guess – is that we will continue to discover beautiful new abstractions forever, in both classical and quantum computing. In practice, people sometimes introduce other ideas into the way they describe quantum computations.
