An important element of the KLM scheme is the conditional sign flip or nonlinear sign flip gate (NS-gate) as shown … The phase shift gate is represented by the matrix: = [] where is the phase shift with the period 2 π. Some common examples are the T gate where = (historically known as the / gate), the phase gate (also known as the ... The cond keyword means that the function can be conditional. See more In quantum computing and specifically the quantum circuit model of computation, a quantum logic gate (or simply quantum gate) is a basic quantum circuit operating on a small number of qubits. They are the building blocks of … See more Quantum logic gates are represented by unitary matrices. A gate which acts on $${\displaystyle n}$$ qubits is represented by a $${\displaystyle 2^{n}\times 2^{n}}$$ unitary matrix, and the set of all such gates with the group operation of matrix multiplication is … See more A set of universal quantum gates is any set of gates to which any operation possible on a quantum computer can be reduced, that is, any other unitary operation can be expressed as a finite sequence of gates from the set. Technically, this is … See more Measurement (sometimes called observation) is irreversible and therefore not a quantum gate, because it assigns the observed … See more The current notation for quantum gates was developed by many of the founders of quantum information science including Adriano Barenco, See more There exists an uncountably infinite number of gates.
