What are quantum error correction codes used for?
a) Correcting programming errors in quantum algorithms
b) Reducing the effects of quantum decoherence and noise on qubits
c) Measuring qubits in quantum computers
d) Building quantum circuits
Answer:
b) Reducing the effects of quantum decoherence and noise on qubits
Explanation:
Quantum error correction codes help reduce the effects of decoherence and noise, preserving the quantum state of qubits during computations.
