class qiskit.circuit.AncillaQubit(register=None, index=None)GitHub Bases: Qubit A qubit used as ancillary qubit. Creates a qubit. Parameters register (QuantumRegister)– Optional. A quantum register containing the bit. index (int)– Optional. The index of the bit in its containing register.Raise...
The first ancilla qubit (the second qubit at the encoder input) is controlled by the information qubit (the first qubit at the encoder input) so that its output can be represented by CNOT12(α|000〉+β|100〉)=α|000〉+β|110〉 (if the control qubit is |1〉 the target qubit is ...
In a general aspect, a quantum computing system includes ancilla qubit devices. In some aspects, a quantum computing system includes a quantum processor cell that includes a superconducting quantum circuit system. The superconducting quantum circuit system includes a tunable-frequency primary qubit device...

(Phys Rev A 52(5):3457, 1995), we can create an n-qubit version of the Toffoli using less gates and the same number of ancilla qubits as recent work using computer optimization. This would be useful in any architecture of quantum computing where gates are cheap but qubit initialization ...
复数:ancillasancillae 英英释义 Ancilla An ancilla bit is a fixed input bit into a logic gate. In reversible quantum computing circuits, an ancilla bit is a prepared fixed qubit state used for input to a gate to give the gate a more specific logic function (i. 以上来源于:Wikipedia学习...
Here, we experimentally demonstrate the use of an ancillary qubit to repeatedly measure the ZZ Z Z ZZ and XX X X XX parity operators of two data qubits and to thereby project their joint state into the respective parity subspaces. By applying feedback operations conditioned on the outcomes of...
Quantum universality by distilling certain one- and two-qubit states with stabilizer operations Quantum universality can be achieved using stabilizer operations and repeated preparation of certain ancilla states. Which ancilla states suffice for unive... BW Reichardt - 《Quantum Information & Computation》...
Specifically, we simulate gates and syndrome measurements on a single qubit of information encoded into the [[7,1,3]] quantum error correction code and determine the output state fidelity as a function of the accuracy with which Shor states (for syndrome measurements) and magic states (to ...
