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 ... 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 27, 2004 · The optical controlled-not gate requires no active stabilization because the two spatial modes share a common path, and it is used to entangle the polarization and … WebAug 9, 2016 · A single qubit gate is to convert a single qubit from one form to another. The commons are quantum NOT gate, X gate and Z gate. NOT gates effect is exchanging the state of 0 and 1, and the Z gate is to add negative sign to logical 1. CNOT gate is an important multiple qubit quantum gate. It contains the control qubit and the target qubit.

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 the first two bits are both set to 1, it inverts the third bit, otherwise all bits stay the same. hungry tums bundabergWebThe Controlled-NOT (CNOT) gate is a two qubits gate, it performs σ x on the target qubit if and only if the control qubit is in the state 1, it has the following transform: ...
