IBM makes quantum computing available over the internet


IBM has opened up its quantum computing research to the web, launching an online simulator that lets anyone run quantum experiments on the company’s hardware. The machine in question isn’t recognizable as a computer to most people — it’s not like you can run Windows on it; it only process basic logical equations. But still, IBM thinks online access will spark interest and pave the way for future developments. “It’s meant to be educational, but also to be the beginnings of a larger framework,” IBM Quantum Computing Group manager Jerry Chow told The New York Times.

Quantum computing is still an esoteric field of research, but in essence, it’s focused around the principle of the qubit or quantum bit. While bits in regular computers are only capable of representing information as 1s or 0s, quantum bits can be 1s, 0s, or both at the same time. This is known as the superposition principle and — in theory — will allow quantum computers of the future to be exponentially more powerful than current devices.

Many companies are trying to find ways to process, store, and read qubits of information, but there’s no established playbook of how to do it. Researchers from different companies (including Google and Microsoft, as well as IBM) have experimented with all sorts of strange machinery to try and master the qubit, including optical lattices, nuclear magnetic devices, and even diamond-based systems. IBM’s own five-qubit computer runs with the help of cryogenic refrigeration, keeping some of its part colder than outer space in order to preserve the fragile information.
