Quantum Decoherence Development Tutorials, Guides & Insights

Now, let's dive into quantum computing, a groundbreaking concept that redefines how we think about computing. Instead of using classical bits, quantum computers use quantum bits, or qubits. While a bit can only represent one state at a time (either 0 or 1), a qubit has the remarkable ability to exist in multiple states simultaneously due to a phenomenon known as superposition.

In the quantum world, things behave in unexpected ways. A qubit, unlike a classical bit, can represent both 0 and 1 at the same time. To better understand this, imagine a spinning coin. Before it lands on heads or tails, it’s in a state of uncertainty—both heads and tails are possible. Similarly, a qubit in superposition represents both possibilities (0 and 1) at the same time, until it is measured.
