Normal computer tends to use binary bits which are representable with 0 and 1 which 0 indicates low and 1 represents high. 0 and 1 cannot simultaneously exist in single gate in normal digital computer. But in quantum computer its different, in a quantum computer, 0 and 1 can indeed coexist at the same time within a single quantum bit or qubit, thanks to the principle of superposition in quantum mechanics. quantum computing has attracted attention as a core technology for the future generation. But as its under consistent development process it’s not fully error corrected. To achieve perfectly error-corrected quantum computers, creating a logical qubit from multiple physical qubits is essential. Here, the basic principles of qubits, as well as the status of the field.
