It's perhaps a very silly question, but in what ways is it advantageous to use GridQubit vs LineQubits to develop quantum circuits? Specially to develop ansatz ? Are GridQubits Cirq's way of representing lattices or possibly surface codes? Thank you

I keep getting a 403 error every time I try to run a code on a quantum computer. Does it mean m

At first when I heard about entanglement, I thought "Neat, so we can make a manipulation on our quantum computer here in such a way that can be interpreted as a binary output somewhere else, and have secure, instant communication of information across vast distance." Then I read an article about...

I'm wondering if you could use a digital signal processor as a quantum computer. I noticed in cellular automata (the kind that are gas automata or one like softology's 2d "fire" automata), that say you see the infinity symbol at the beginning everywhere in the blinking lights. As it progresses,...

A code (similar to the portfolio shown in qiskit tutorials), whose solution can be found through the IBM's simulator, remains running on ibmq melbourne, like stuck on a loop; by the time it is completed, another one is pending.

If our input $x \in \{0, 1\}^{n}$ is given as a black box, we usually query an oracle as follows. $$O_{x}|i, b \rangle = (-1)^{b x_{i}} |i, b \rangle$$ $i = \{1, 2, \cdots, n \}$ is the index of the input we are querying. $x_{i}$ is the value at that index. $b = \{0, 1\}$ is an arbitrary Boolea...
