Hardware Flashcards
What are the quantum computing “ingredients”?
Superposition
Interference
Entanglement
What are the DiVincio criteria?
scalable physical system w/ well-characterized qubits
qubits can be initialized to simple state
long T2
universal set of gates
measurement capability
What are T1 and T2?
T1: Spin lifetime
T2: Spin decoherence time
