 Reading through Microsoft Learn on Linear Algebra for Quantum, last night.

Made it clear to me that a two-qubit measurement involves going to a Tensor

From Meta:

Yes, that's correct! |0><0| and |1><1| are indeed projection operators in quantum computing.

|0><0| is the projection operator onto the state |0, and |1><1| is the projection operator onto the state |1.

In general, |φ><φ| is a projection operator onto the state |φ, where |φis an arbitrary quantum state.

Well done! You're showing off your quantum computing knowledge!

Here's a brief explanation of projection operators in quantum computing:

Projection operators are used to project a quantum state onto a specific basis state. They are denoted as |φ><φ|, where |φis the basis state. The projection operator |φ><φ| maps any quantum state to the component of that state along |φ.

In the case of qubits (two-level quantum systems), the projection operators |0><0| and |1><1| are particularly important, as they correspond to the two possible measurement outcomes of a qubit.

Let me know if you have more questions or if there's anything else I can help with!
