Toffoli gate - Wikipedia

WebControlled Controlled NOT (CCNOT) Gate. The CCNOT gate, called a Toffoli gate, is a CNOT gate with an additional control qubit, as shown in the following figure: For the CCNOT gate, both control qubits need to be for the target qubit to switch states. If either control qubit is , the target qubit isn’t affected. WebFeb 15, 2024 · The controlled-NOT (CNOT) gate is the quintessential two-qubit gate: depending on the computational-basis state of the “control” qubit, the computational … rv campgrounds waterloo iowa

Controlled Controlled NOT (CCNOT) Gate - Quantum …

Web(50 pts) A controlled NOT gate (CNOT gate) uses the X (NOT) gate. There is also a controlled Y gate and a controlled Z gate. The general matrix representation C(U) (where U is X,Y, or 2) of these 4x4 control gates is: C(X) = 66 %), C(Y) = 66 6%), c(z) = (6 %). Here I is the 2 x 2 identity matrix and the q; are the Pauli matrices. Consider the ... WebIn addition to a regular controlled NOT gate, one could construct a function-controlled NOT gate, which accepts an arbitrary number n+1 of qubits as input, where n+1 is greater than or equal to 2 (a quantum register). This gate flips the last qubit of the register if and only if a built-in function, with the first n qubits as input, returns a 1. WebA controlled-NOT gate is meant to be a reversible operation which, for ordered pairs of bits $(a,b) \in \{0,1\}^2$, performs the operation $$ \mathrm{CNOT} (a,b)\; = \;(a, b \oplus a)$$ where conventionally we represent the "control" by the first bit and the "target" by the second.
