I'm a bit confused about entanglement with regards to quantum computing. I'm not an expert by any means, but I've been reading around about quantum computing and was confused about something.(adsbygoogle = window.adsbygoogle || []).push({});

I've read that, you can't directly observe a qubit, because if you do the wave function will collapse and it will be no better than a classical bit, so experimenters are using entanglement to get information about other qubits, enabling them to do parallel computing on a single qubit. However I'm failing to see how a qubit can still perform parallel computing, if once one qubits state is observed, both entangled qubits wave functions collapse. So I'm thinking that entanglement just gets you 2 classical bits, with the effort of only measuring one.

Can anyone tell me how this enables parallel computing within a single qubit?
