While it is impossible to completely

While it is impossible to completely remove noise from the system, the objective is to limit it to the extent of providing sufficient time for computation. This is called quantum error correction. Due to noise, the physical qubits comprising the quantum computer get eaten up by the system, which then drastically reduces the number of functional or “logical” qubits – the ones which are capable of performing computations. So, for instance, the maximum number of physical qubits in a quantum processing chip is a little over 1,000, a feat which has been achieved by both IBM and Atom Computing, a California-based startup. However, these have limited practical utility due to a lack of error correction. สล็อตเว็บตรง
