All 10 questions. After you submit, each question shows the right answer and why. Back to the quick check
Unlike an ordinary bit, a qubit can be in a mix of 0 and 1.
Why are qubits so hard to look after?
Each extra qubit doubles the number of 0-and-1 combinations a set of qubits can hold in superposition. How many combinations can 5 qubits hold?
A quantum computer solves problems by trying every possible answer at the same time and then reading out the best one.
What did Peter Shor's 1994 quantum algorithm show could be done quickly on a large quantum computer?
What did NIST release on 13 August 2024?
Which statement about two leading kinds of qubit matches NIST's description?
Suppose each quantum operation independently has a 1-in-1000 chance of error. What is the probability that a computation of 500 operations has no error at all? Give your answer to two decimal places.
Why do researchers think quantum error correction will be essential, and why is it not a quick fix?
Critically assess the claim: 'Once quantum computers are large enough, every hard computational problem will become easy.'
