Performing Binary Operations on Classical Bits
I am trying to prepare the n-qubits GHZ state using LOCC on Qiskit. The implementation uses the result of some mid-circuit measurements for later operations. I am now using something like
with circ.if_test((cr[0],1)):
with…

Classical Analog of Information-Theoretic Version of Knill-Laflamme Conditions
One version of the Knill–Laflamme conditions for quantum error correction is stated as follows:
Theorem 9.5 in Gottesman's Quantum Error Correction Book:
Let $ \mathcal{F}: L \to Q $ be a quantum channel. Let $ R $ be a reference system whose…

Do quantum teleportation require transmission media?
It said on wikipedia:
Because classical information needs to be sent, quantum teleportation cannot occur faster than the speed of light.
So does it mean quantum communication specifically teleportation still need transmission media like fiber…

Can you project on an orthogonal basis for a multipartite system using only local measurements and classical communication?
Say Alice possesses one qubit, and Bob two, and that the joint state is $|\psi_{A, B_1, B_2}\rangle = \alpha|n_1\rangle + \beta |n_2\rangle$, where $|n_1\rangle$ and $|n_2\rangle$ are orthonormal basis states for the combined Hilbert space. If you…

are decoders based on syndrome equivalent to ones based on data
In Mackay book (page 559) I beleive the author claims that you get the same performance whether you decode using the raw received codeword (possibly soft LLR's) or using the syndrome of hard decision data from what's received (and some other…
