Fault-tolerant quantum computing involves the development of quantum systems capable of performing complex calculations without errors due to decoherence or other noise sources, making it feasible for practical applications.
Overcoming the limitations of current noisy intermediate-scale quantum (NISQ) devices, which are prone to errors that can accumulate quickly in calculations, making practical applications infeasible.
These systems use error-correcting codes and physical redundancy to protect qubits from environmental disturbances. They employ techniques like surface codes and topological qubits to maintain the integrity of quantum information during computations.
The manufacturing process involves precise control over qubit fabrication and integration into larger systems. This requires advanced materials science and cleanroom environments.
Involves designing quantum circuits, selecting appropriate qubit types (e.g., superconducting, ion traps), fabricating the hardware, assembling the system, and programming the algorithms to run on these devices.
