Teams at Google, Microsoft, Intel, IBM and various startups and academic labs are racing to become the first to achieve quantum supremacy – the point where a quantum computer can run certain algorithms faster than a conventional version.
The purpose of Bristlecone, Google says, it to provide its researchers with a testbed “for research into system error rates and scalability of our qubit technology, as well as applications in quantum simulation, optimisation, and machine learning.”
One of the issues that quantum computers have to contend with is error rates. Quantum computers typically run at extremely low temperatures and are shielded from the environment because quantum bits are highly unstable and any 'noise' can lead to errors.
Because of this, the qubits in modern quantum processors (the quantum computing versions of 'bits') are often a combination of numerous bits to help account for potential errors. Another limiting factor is that most of these systems can only preserve their state for microseconds.
