Qubit encoding

There seems to be some inconsistency in the encodings used for qubits in optical modes in this article. Qubits and modes seems to describe encoding a single qubit per mode by the presence of absence of a photon, whereas the Hadamard in Implementations of elementary quantum gates is clearly encoded in two modes, presumably by which mode the photon is in. I attempted to clarify the diagrams for Hadamrd and CNOT in light of this, but if possible sticking primarily to one encoding (while mentioning the other as an alternative) might make the article more accessible. — Preceding unsigned comment added by Azaghal of Belegost (talk • contribs) 07:49, 25 January 2014 (UTC)[reply]

Inconsistent figure

The picture showing the implementation of the CNOT gate does not seem right. While the top part indeed shows a CNOT implementation, the implementation shown in the bottom part uses only one input qubit (and hence cannot be a controlled gate). --2001:67C:10EC:52CB:8000:0:0:13FA (talk) 16:11, 15 July 2016 (UTC)[reply]

clarifying that there are variants of LOQC

The KLM is a LOQC model which is universal for quantum computation. Yet there are other models that are not universal. such models are also important, e.g., due to solving the boson sampling problem that is believed to be beyond the ability of a polynomial regular computer. I did several modifications to clarify this point.Tal Mor (talk) 12:34, 7 December 2016 (UTC)[reply]

Spliting this page to KLM Protocol and LOQC =

I suggest that this page be split into pages titled KLM Protocol and Linear optical quantum computing. The page "KLM Protocol" will discuss the KLM model and LOQC will compare between the known models (KLM and Boson Sampling) I am currently working on those two pages and intend to make the split in the following days 21:23, 30 December 2016 (UTC) — Preceding unsigned comment added by Yaniv.N (talk • contribs)
