WebJan 28, 2009 · Gates acting on more than two qubits are appealing as they can substitute complex sequences of two-qubit gates, thus promising faster execution and higher … 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.

WebJun 14, 2024 · Given those four catalyst states, Hadamard+Toffoli is universal because it can synthesize Hadamard+T+CNOT (which is universal). Note that it is important that the circuit not consume the catalyst states. This is what distinguishes Toffoli+H from the Clifford gate set (which can synthesize T gates only by consuming the magic states). … WebUS20240080126A1 US18/045,102 US202418045102A US2024080126A1 US 20240080126 A1 US20240080126 A1 US 20240080126A1 US 202418045102 A US202418045102 A US … WebMay 2, 2024 · The three-qubit Toffoli gate is universal for reversible classical computation, enabling arbitrary Boolean operations over quantum registers 1.Moreover, together with … shuichi full body sprite
