Fricke Topological Qubits
Round 1
Reviewer 1 Report
In the paper, the author used the theory of algebraic surfaces including the character variety to develop a new kind of topological quantum computing.
Fortunately, the authors are honest that they don't find any durect realization of their ideas in a new device. But alle ideas sound interesting and relevant.
At the end I have only one problem: I miss a good conclusion of the paper. What is now possible when one use these ideas? What is the main motivation to use the Fricke surface? How one can define topological qubits from the cubic surface?
Author Response
We thank the first referee for his report.
The referee would like a conclusion. By the way, the discussion is at the same time our conclusion.
At the moment we do not have the concept of an experiment so that we cannot discuss more.
In the introduction, we added a sentence (and the related references) about the status of experiments on quantum computing.
Reviewer 2 Report
The subject of proposing a non-anyonic theory of a topological quantum computer based on surfaces in a three-dimensional topological space for topological quantum computing field. Therefore, the authors should extend the part about the implementation of quantum computation in more general way. The implementation of quantum computation should be discussed for some real physical systems in the introduction and cited: J. Phys. A: Math. Theor. 45 (2012) 485305; Ann. Phys. 334 (2013) 47;J.Opt.

In conclusion, I recommend the revised version for publication in Quantum Reports.

We thank the second referee for his report. Following his proposal, we added a sentence (and the related references) about the status of experiments on quantum computing.
Building a quantum computer is still challenging. But progress has been performed using natural and artificial atoms \cite{Buluta2011}, superconducting technology \cite{Obada2013}
and other physical techniques \cite{Top10,TimelineofQC}. One of the greatest challenges involved with constructing quantum computers is controlling or removing quantum decoherence.
One possible solution is to create a topological quantum computer.
