Sample interview questions: Can you explain the concept of quantum computing with topological qubits and its advantages?
Sample answer:
- Topological qubits:
Topological qubits, unlike traditional qubits, store quantum information in the topological properties of matter, specifically in the braiding of non-Abelian anyons. These anyons are quasiparticles that obey exotic statistics, allowing for more robust and fault-tolerant operations.

Advantages of topological qubits:
-
Increased Stability: Topological qubits are less susceptible to noise and decoherence, making them more robust and reliable. This stability stems from their inherent protection against local errors due to their non-Abelian nature.
-
Fault-Tolerant Operations: Braiding operations on topological qubits can be made fault-tolerant, meaning that errors introduced during braiding can be corrected without compromising the overall quantum state. This fault tolerance is crucial for building scalable quantum computers.
-
Efficient Quantum Gates: Certain topological qubit systems allow for the implementation of quantum gates, such as the controlled-NOT (CNOT) gate, with high fidelity and efficiency. This enables efficient computation and manipulation of quantum information.

Scalability: Topological qubits have the potential for easier scalability compared to other qubit types. Their braiding operations can be performed in a modular fashion,… Read full answer
