Unlike classical computers

Unlike classical computers, which use bits as carriers of information, quantum computers use qubits for the same purpose. These qubits are particles such as photons (particles of light), electrons, etc. Since these are microscopic particles, they exhibit quantum behaviour and are incredibly susceptible to the external environment. The slightest disturbance due to temperature fluctuations or electromagnetic fields can cause the information contained by them to start decaying, a phenomenon known as quantum decoherence or “noise,” which is the primary obstacle in building quantum computers. สล็อตเว็บตรง
