It can be used for universal reversible classical computation, and also forms a universal set of qubit gates in quantum computation together with a Hadamard gate. Furthermore, it is a key element ...

In tandem with the Hadamard gate, the Toffoli gate forms a universal quantum gate set, which allows researchers to run any quantum algorithm. Experiments implementing multi-qubit gates in major ...

So as the quantum NOT gate inter-converts the states 0 and 1, its action is to swap the contributions of the basis states in the superposition. The Hadamard gate is a type of gate that acts on a ...

For example, a simple Hadamard gate chain was implemented on FPGA to simulate the state transition of qubits. This design validates the feasibility of the FPGA-based digital quantum computing model.
