Quantum process tomography reconstructs the full description of a quantum operation from measurements. Methods, costs, challenges and uses.
Quantum process estimation characterizes what a quantum operation actually does. Process tomography, gate fidelity and randomized benchmarking.
How quantum circuits are designed and compiled: gate decomposition, qubit mapping, depth reduction, parallelization, synthesis and benchmarking.
When quantum computers are faster than classical ones and when they are not, with Shor’s and Grover’s algorithms as worked examples.
Why quantum computers cost millions: superconducting and trapped-ion hardware, cryogenic cooling, error rates, and what drives prices up.
