Qubits are represented as (for example) quantumly entangled electron spins. And due to the nature of quantum physics, they are not very stable, and you cannot measure a value without influencing it.

Granted, my knowledge of quantum computing is very hand-wavy.

Yeah he beat that horse to death but he has a point.
