Quantum Bits (Qubits)
What are Qubits?
A qubit is a tiny particle that can exist in two states at once, unlike regular computer bits that can only exist in one state or the other.
This makes qubits extremely powerful for performing complex calculations because they can consider many different possibilities at the same time.
Qubits are a key component of quantum computers, which are being developed to solve problems that regular computers can't handle. So, in a way, you can think of qubits as the galactic heroes of the computer world - capable of incredible feats that are beyond the abilities of ordinary bits.
Qubit is any object that can be manipulated to be in superposition.
Physically it can be little coils where a current can flow through in two energy states that represent 1 and 0. And if you cool these coils enough to slightly above absolute 0 then they superconduct and the current can be in a superposition of two different states.
Rather than simply switching electron flow on or off, qubits require control over tricky things like electron spin. To create a qubit, scientists have to find a spot in a material where they can access and control these quantum properties.
Once they access them, they can then use light or magnetic fields to create superposition, entanglement, and other properties.
Qubits are also what constitute the memory of your quantum computer.
