- nabla9 8y agoSo why it's not taken into account when quantum-entanglement records are broken? You can have flasks of superfluid 4He with thousands of moles of entangled atoms clearly visible.
- barbegal 8y agoQuite correct but usually quantum-entanglement records are for qubits rather than generic atoms. And qubits must be able to be measured in isolation e.g. the polarisation of a single photon can be measured. With superfluid 4He you can't isolate the qubits.
- nabla9 8y agoAh, that makes sense. Thank you.
