The lack of symmetry in qubits does not fix errors in quantum computing because the errors that occur in quantum systems are not solely due to the lack of symmetry in qubits. Quantum computing errors can arise from various sources, such as environmental noise, imperfect control operations, and interactions with surrounding particles. These errors are typically referred to as quantum decoherence and can cause the loss of information and the degradation of quantum states.
Symmetry in qubits refers to the property where the qubit states are evenly distributed and do not favor any specific state. While symmetry can be desirable for certain properties of qubits, such as their sensitivity to noise or the ability to perform fault-tolerant computations, it does not directly address the fundamental challenges of quantum decoherence and error correction.
On the other hand, the lack of symmetry between matter and antimatter could potentially explain the matter-antimatter asymmetry observed in the universe. According to the Big Bang theory, matter and antimatter were created in equal amounts during the early stages of the universe. However, if matter and antimatter were perfectly symmetric, they would annihilate each other completely, leaving behind a universe devoid of matter.
The fact that we observe a universe dominated by matter suggests that there is an asymmetry between matter and antimatter. This asymmetry, known as CP violation, refers to the violation of the combined symmetry of charge conjugation (C) and parity (P). CP violation is a well-established phenomenon in particle physics and is thought to be responsible for the matter-antimatter asymmetry.
The exact origin of CP violation and the matter-antimatter asymmetry is still an active area of research in particle physics. It involves studying the behavior of subatomic particles and their interactions within the framework of quantum field theory. While the lack of symmetry in qubits and the matter-antimatter asymmetry share the notion of symmetry, they are distinct concepts operating at different scales and contexts.
