Shroedinger lived together with his cat...
Or may be the state was completely inverse
It doesn't matter - much better
That Josephson made his junction
With very important function

People were happy about Josephson
Because his junction with very important function
Was not the Ghan diod
It was not the Shotke diod
It was real transmon (and also fluxon)

The quantum information is coming
Through the Josephson junction
In order to perform the prediction function
Q-bits are transfering from transmon to the fluxon -
How smart was old budy Josephson!

Nobody needs to analyse anything -
All will be made by Quantum Computer
The complexity of problem doesn't matter
And You, my friend, much better
Learn how to play music on klavisin

But if You like physics
You have not to be sad because of quantum field -
Anybody in the Universe (including Quantum Computer)
Can not the right, real and complete propogator build
