Quantum Gates

Save

Quantum gates are fundamental building blocks of quantum computers, devices that harness the power of quantum mechanics to perform complex calculations far beyond the capabilities of classical computers. Each gate represents a specific quantum operation that manipulates qubits, the quantum mechanical analog of classical bits, to create quantum circuits. These circuits can then be combined to construct larger quantum algorithms for solving various computational problems.

How Quantum Gates Work

Quantum gates operate on the principle of superposition, where qubits can exist in both 0 and 1 states simultaneously. They manipulate the quantum state of qubits using unitary matrices, which preserve the probability distribution of the states. These gates can perform various operations, such as:

  • Hadamard gate: Superposes a qubit into a state that is equal parts 0 and 1.
  • CNOT gate: Flips the target qubit if the control qubit is 1.
  • Swap gate: Exchanges the states of two qubits.
  • Controlled-NOT gate: Flips the target qubit if the control qubit is 1.
  • Toffoli gate: Flips the target qubit if both control qubits are 1.

By combining these gates, complex quantum circuits can be constructed to perform tasks such as:
