Quantum Chip Outperforms Supercomputer
Google's Quantum AI team has made a significant breakthrough with its 105-qubit Willow chip, which solves complex calculations 13,000 times faster than the fastest supercomputer.
The Willow chip uses a new algorithm called Quantum Echoes to run complex calculations, producing results that are both faster and verifiable, with fewer errors.
The findings demonstrate that the Willow chip can solve a complex calculation in about three hours, whereas the fastest supercomputer would take five years.
- The Quantum Echoes algorithm measures how information spreads within a quantum system.
- It performs a sequence of operations, slightly alters one qubit, and then reverses the process to compare results.
This marks the first time a quantum processor has produced results that are both faster and verifiable, addressing one of the key criticisms of earlier quantum experiments.
