What scenario does the woman tell the undergrad is really hard for standard computers to do that would
be easier if done by a quantum computer? - ANSWER✔✔-simulating the system of nature
How are qubits coded as described to the grad student? - ANSWER✔✔-with microwave pulses of
different frequencies and durations that will put the qubit(s) into a certain state of quantum
computation
