Principle of the CSWAP gate is to swap the inputs when the controller bit is set (logic high), and to rehash the inputs when the controller bit is reset …

WebBut, consider the classical NOT gate. If the input is $0$ it ouputs $1$, while if the input is $1$ it outputs $0$. Since this mapping is one-one, it can be easily implemented as a reversible unitary gate, namely, the Pauli-X gate. However, for implementing a classical AND or a classical OR gate we need to think a bit more. Consider the CSWAP ... WebHence, any two-qubit quantum can be represented as 4 × 4 matrix in the computational basis states (3). One of the useful two-qubit gates is a controlled-NOT or CNOT gate, its graph- ical and ...
WebQuantum gates/operations are usually represented as matrices. A gate which acts on a qubit is represented by a \(2\times 2\) unitary matrix \(U\). The action of the quantum gate is found by multiplying the matrix representing the gate with the vector which represents the quantum state. ... qc. cswap (q [0], q [1], q [2]) qc. draw [52]: q24_0 ... WebThis gate lets you define how many control qubits you would like to include (perhaps the majority of your quantum register) and define a control state. from qiskit import * my_circuit = QuantumRegister (3,3) my_circuit.append (circuit.library.MCXGate (2, ctrl_state='10'), [0,1,2]) Check out the documentation here.
WebCSWAP (Fredkin Gate) The control-SWAP gate, or CSWAP gate, is also called the Fredkin gate, named for Ed Fredkin. If the control bit is zero, the other two bits are left alone. If the control bit is one, the other two bits are swapped. input (A) input (B) input (C) output (A’) WebFor qubits, the gate set {cSWAP, CNOT, Hadamard} is equivalent to {Toffoli, Hadamard} which is universal [41]. For both discrete and continuous variables, ...

The Fredkin gate (also CSWAP gate and conservative logic gate) is a computational circuit suitable for reversible computing, invented by Edward Fredkin. It is universal, which means that any logical or arithmetic operation can be constructed entirely of Fredkin gates. The Fredkin gate is a circuit or device … See more The basic Fredkin gate is a controlled swap gate that maps three inputs (C, I1, I2) onto three outputs (C, O1, O2). The C input is mapped directly to the C output. If C = 0, no swap is performed; I1 maps to O1, and I2 maps to O2. … See more The Fredkin gate can be defined using truth functions with AND, OR, XOR, and NOT, as follows: O1 = I1 XOR S O2 … See more Three-bit full adder (add with carry) using five Fredkin gates. The "g" garbage output bit is (p NOR q) if r=0, and (p NAND q) if r=1. Inputs on the left, … See more • Quantum computing • Quantum gate • Quantum programming See more One way to see that the Fredkin gate is universal is to observe that it can be used to implement AND, NOT and OR: If I2 = 0, then O2 = C AND I1. If I2 = 1, then O1 = C OR I1. If I1 = 0 and I2 = 1, then O2 = NOT C.
