A quantum circuit is a sequence of quantum gates applied to qubits, representing the operations in a quantum computation. Each gate changes the qubits’ state using quantum mechanics principles like superposition and entanglement. The final qubit states, when measured, yield the circuit’s computational result probabilistically.

Quantum Computing is a different kind of computation that builds upon the phenomena of Quantum Mechanics. Learn more about Quantum Computing isn’t programming. It’s choreography.
Every time you treat a A quantum circuit is a sequence of quantum gates applied to qubits, representing the operations in a quantum computation. Each gate changes the qubits’ state using quantum mechanics principles like superposition and entanglement. The final qubit states, when measured, yield the circuit’s computational result probabilistically. Learn more about Quantum Circuit like a set of instructions, you kill the very thing that makes it powerful.
Because a circuit doesn’t run; it exists — as one precise, reversible transformation of reality itself.
Once you see that, the confusion around gates, Superposition in quantum computing means a quantum bit (qubit) can exist in multiple states (0 and 1) at the same time, rather than being limited to one like a classical bit. Mathematically, it’s a linear combination of basis states with complex probability amplitudes. This allows quantum computers to process many possible inputs simultaneously, enabling exponential speedups for certain problems. Learn more about Superposition and Entanglement is a quantum phenomenon where two or more particles become correlated so that measuring one instantly determines the state of the other, no matter how far apart they are. This correlation arises because their quantum states are linked as a single system, not as independent parts. It doesn’t allow faster-than-light communication but shows that quantum systems can share information in ways classical physics can’t explain. Learn more about Entanglement evaporates.
Let’s flip that mental model and look at what a A quantum circuit is a sequence of quantum gates applied to qubits, representing the operations in a quantum computation. Each gate changes the qubits’ state using quantum mechanics principles like superposition and entanglement. The final qubit states, when measured, yield the circuit’s computational result probabilistically. Learn more about Quantum Circuit really is — not a program, but the mathematics of evolution.
