A universal set of gates are able to mimic the operation of any other gate type, given enough gates. For example, a universal set of quantum gates are the Hadamard(H), the pi/8 phase shift(T), and the CNOT gate. How would one disprove or prove universality of a set of gates such as {H,T}, {CNOT,T...
From a 9×9 Hamiltonian lying 9D space, I choose a certain subspace of 4D for designing a two qubit gate. Now the original unitary time evolution operator also lies in 9D space and it's a 9×9 size matrix. For action of unitary time evolution operator on the two qubit gate made out of 4D subspace i...
The Classical Channel
I have had a few ideas for circuits that I would like to get feedback on (do such things already exist, what utility they serve, etc).
Any suggestions on how I might graphically render these?
Example:
o
i-/->\
\<-/
Here i is the input & o is the output. The slash directly to the ri...
I have the following operation in my .qs files:
operation myOp(qubits: Qubit[]) : () {
// uses elements from the qubit array
}
How do I send an array of qubits to this in the driver file?
The following did not work:
Qubit[] qubits = new Qubit[2];
myOp.Run(sim, qubits);
I got t...
If quantum computers advance to the point where they can defeat RSA, DSA, SHA (and really all existing classical public key encryption or and authentication) then it appears that it would be impossible to make secure transactions on the internet.
It would be impossible to maintain the security...
