Overview
Quantum coherence is well preserved in nature by symmetry and structural perfection. A fundamental challenge in quantum information processing is to develop architectures which allow coherent signals to be exchanged in a resource efficient manner without inducing classical behavior.
The quantum processor team focuses on developing long-lives superconducting quantum bits that are custom designed for specific computing applications.
Major Research Foci
The high-level goals of QPU design revolve around generating multi-qubit devices with a modular architecture. Entanglement then has to be efficiently generated within the chip and passed onto to classical circuitry.
