Introduction to the D-Wave Quantum Hardware Schematic of a superconducting qubit, the basic building block of the D-Wave quantum computer. The arrows indicate the magnetic spin states which encode the bits of information as +1 and -1 values. Unlike regular bits of information, these states can be put into quantum mechanical superposition.Quantum Computing Primer · D-Wave Systems Quantum computing circuit | TechLink A quantum bit, or qubit, is the building block of a quantum computer. Qubits are different from conventional bits whereby quantum behavior enables a superposition of states (0 and 1) at the same time with varying occupancy probability. This property enables quantum computers to perform simultaneous operations on 2^N information states.
