Webb4 mars 2024 · Quantum dots are not uniformly sized therefore the eigenenergies of each quantum dot state will vary about some overall average. The probability that a state will be filled will vary from dot-to-dot. This is taken into account by weighting the Fermi function with a Gaussian function. 22 0 2 2 ( )DD( ) ( ) cc zzmnl mnl f n G E f dE NN n E E LL f Webb10 apr. 2024 · Quantum 101. Quantum computers harness the laws of physics at the tiniest scales. Classical computers encode information in bits, usually represented as either a 0 or a 1. But quantum computers use quantum bits, or qubits, which can exist in a “superposition” of states – a combination of both 0 and 1 simultaneously.
