The CNOT (Controlled-NOT) gate is the standard two-qubit gate in quantum computing. It takes two qubits as input: a control qubit and a target qubit. If the control qubit is in state 1, the target qubit is flipped (0 becomes

Quantum Simulation
In 1981, physicist Richard Feynman pointed out a fundamental mismatch in computer science. Nature is inherently quantum mechanical, but the computers we use to model it are strictly classical. He proposed a direct solution. If you want to make an

Quantum Speedup
Quantum computing is not a faster version of classical computing. If you could run a standard word processor or web browser on a quantum machine, it would likely run slower than it does on your smartphone. The concept of quantum

Quantum Sensing
The same fragility that makes quantum computing so difficult to build makes quantum systems extraordinarily useful as sensors. A qubit is sensitive to everything around it: magnetic fields, electric fields, temperature, pressure, gravity, rotation. In a quantum computer, this sensitivity
