Whereas a classical bit is either a 0 or 1, a quantum computing bit (the "qubit") can be both a 0 and a 1 or any value in between at the same time. Meaning "many possibilities," superposition ...

For example, virtual qubits can exist as a superposition of 0 and 1. Similarly, superconducting qubit, which is a physical electronic device, also has lower and higher energy states represented by ...

The first step in the roadmap is the creation of a cat qubit, a special type of qubit ... while regular qubits demonstrate only a single superposition, cat qubits can exist in double superposition.
