6 Questions
Which conditions must a density operator satisfy to be associated with an ensemble?
Trace and positivity conditions
What is the significance of the trace condition for a density operator?
It ensures that the probability of the ensemble is conserved
What is the positivity condition for a density operator?
The operator must have positive eigenvalues
Which of the following is an advantage of using superconducting qubits for quantum computing?
They can be designed and fabricated by us
What is the main disadvantage of using fabricated superconducting qubits for quantum computing?
Fabrication uncertainty means no two qubits are the same
What is the key difference between superconducting qubits and truly quantum two-level systems provided by nature?
Superconducting qubits are multi-level systems that we fabricate ourselves
