Today we presented Bristlecone, our new quantum processor, at the annual American Physical Society meeting in Los Angeles. The purpose of this gate-based superconducting system is to provide a testbed for research into system error rates and scalability of our qubit technology, as well as applications in quantum simulation, optimization, and machine learning.
Here is a bit more informationBWV said:So how does it work? What is the underlying mechanism by which it is able to quantum computations?
Quantum supremacy means a quantum computer outperforming classical supercomputers in some task (it doesn't really matter which supercomputer you choose - once quantum computers beat one in a given task they will quickly beat all in this task). Before that step is reached they are interesting research objects only.We are cautiously optimistic that quantum supremacy can be achieved with Bristlecone
A quantum processor is a type of computer processor that uses quantum bits, or qubits, instead of traditional binary bits to store and process information. This allows for more complex and powerful computing operations, particularly in the field of quantum computing.
Bristlecone is a 72-qubit quantum processor, which is significantly more powerful than Google's previous quantum processor, which had only 9 qubits. This increase in qubits allows for more complex and accurate quantum computing operations to be performed.
Quantum computing has the potential to greatly impact a variety of industries, from medicine and chemistry to finance and artificial intelligence. Bristlecone and other quantum processors could help solve complex problems and simulate systems that are currently beyond the capabilities of traditional computers.
Quantum supremacy refers to the ability of a quantum computer to solve a problem that is practically impossible for a traditional computer to solve. Bristlecone has enough qubits and low enough error rates to achieve quantum supremacy, meaning it can perform calculations that would take traditional computers thousands of years to solve.
Despite its potential, quantum computing still faces many challenges and limitations. One of the biggest challenges is controlling and correcting for errors that can occur in qubits. There are also limitations in the types of problems that quantum computers can solve, as they are best suited for optimization and simulation problems rather than general purpose computing tasks.
