I’m studying the HHL alghoritm and I’m trying to do an his implementation but, there are some points that I don’t understand:

1) how can I transform my hermitian Matrix into his unitary operator?

2)when I have to do controlled rotation conditioned on the eigenvalue, I know that the angle Is equal ti arcsin(C/lambda), but if I don’t know the eigenvalue how I can implement this rotation? ]]>

Starting on February 24th at 12:00pm PST, this four-day global programming contest will provide an introduction to quantum computing and tools for developers to dig deeper into this field.

I’ve just started to learn Quantum Computing online via MOOC platforms and it’s very good. Just dropping links to among this awesome forum to get benefits of it.

There are thousands of articles, books and web sites describing the Hadamard Gate from a theoretical point of view.

But I haven’t been able to find any picture about a real implementeation of a Hadamard Gate on superconducting circuits nor any article describing how to make one.

Only some articles speaking about optical implementation of Hadamard gates:

https://ieeexplore.ieee.org/document/5612120%20https://arxiv.org/pdf/quant-ph/9706022.pdfhttps://ieeexplore.ieee.org/document/5612120%20https://arxiv.org/pdf/quant-ph/9706022.pdf

Maybe the following is the only one I’ve found with some information, though quite theoretical too:

https://www.nature.com/articles/s41598-019-49657-1https://www.nature.com/articles/s41598-019-49657-1

How are Hadamard gates fabricated (or created in the laboratory) and operated?

]]>If you can complete the quick survey below on Quantum Computing and the possible impact on Cyber Security it will be much appreciated.

It is for my dissertation on MSc Cyber Security and it is totally anonymous!

Also if someone is willing to complete an interview document with 8 questions on the same topic that would be awesome as well.

Thanks in advance.
