Many qubits
Intermediate · 1 lesson · 5 activities
What changes when one qubit becomes several: outcomes multiply rather than add, bit order starts to matter, measuring one qubit reshapes the rest, and the Bloch sphere stops being able to show you the state at all.
Lessons
More than one qubit
Outcomes multiply, bit order matters, measuring part of a register changes the rest — and the picture you have been using runs out.
