Quantum computing is revolutionizing the field of computing by leveraging the principles of quantum mechanics. But what exactly is quantum computing and how does it work? In this guide, we'll break down the basics of quantum computing so you can understand how this emerging technology might reshape the future of computation.
What is Quantum Computing?
Quantum computing is a new paradigm for computing that uses quantum bits (or qubits) as the fundamental unit of information processing. Unlike classical bits that represent information as 0 or 1, qubits use quantum states that can be in superposition of both a |0〉 and |1〉 state at the same time.

Quantum Entanglement
One of the most fascinating aspects of quantum computation is quantum entanglement. When qubits become entangled, the state of one qubit is directly related to the state of another, regardless of the distance between them.
A qubit can be in a state of entanglement—a quantum connection between two particles that lets scientists create quantum bits, or qubits.
Quantum Gates
Quantum algorithms operate using quantum gates that manipulate qubit states using unitary operators.

return np.
