a scalable method for benchmarking a quantum computer’s capability. a–c, Mirror circuits—quantum circuits with a reflection structure—can be used to efficiently benchmark arbitrarily large...
To better understand quantum computing, this paper examines the foundations and vision based on current research in this area. We discuss cutting-edge developments in quantum computer hardware advancement and subsequent advances in quantum cryptography, quantum software, and high-scalability quantum computers.
Part I provides a broad overview of the main ideas and results of the field of quan- tum computation and quantum information, and develops the background material in computer science, mathematics and physics necessary to understand quantum compu- tation and quantum information in depth.
20 Δεκ 2021 · Quantum computers can now run interesting programs, but each processor’s capability—the set of programs that it can run successfully—is limited by hardware errors.
Agenda. Part I: Quantum-computing fundamentals. High-level motivation, history, and status. Qubits, multi-qubit states, and quantum measurement. Review of notation. Quantum gates and quantum circuits. Part II: Circuit-model quantum computing. Quantum gates and quantum circuits (cont.)
The fundamentals of quantum computing are then introduced - reversible logic gates, qubits and quantum registers. The key quantum property of ‘entanglement’ is described, with due homage to Einstein and Bell. As an illustration of a quantum program, Grover's database search algorithm is described in some detail.
discuss quantum teleportation, the Bennett-Brassard quantum scheme for secure com- munication, and some further features of quantum states when viewed as information carriers.
