Quantum toffoli gate
Did you know?
In logic circuits, the Toffoli gate (also CCNOT gate), invented by Tommaso Toffoli, is a universal reversible logic gate, which means that any classical reversible circuit can be constructed from Toffoli gates. It is also known as the "controlled-controlled-not" gate, which describes its action. It has 3-bit inputs and outputs; if … See more An input-consuming logic gate L is reversible if it meets the following conditions: L(x) = y is a gate where for any output y, there is a unique input x. The gate L is reversible if there is a gate L′(y) = x which maps y to x. … See more Any reversible gate that consumes its inputs and allows all input computations must have no more input bits than output bits, by the See more Any reversible gate can be implemented on a quantum computer, and hence the Toffoli gate is also a quantum operator. However, the Toffoli gate can not be used for universal quantum computation, though it does mean that a quantum computer can … See more • CNOT and Toffoli Gates in Multi-Qubit Setting at the Wolfram Demonstrations Project.
