1.4.1 Combining multiple qubits – tensor product of density matrices

Course subject(s) 01. Quantum tools and a first protocol

Hm… if I tell you the density matrix of one qubit – let’s call it A – and the one for another qubit – let’s call it B – how can we write down the state of both qubits A and B together?

Watch the video below to find out!

Sorry but there don't seem to be any downloads..
