      Abstract: Digital computers can perform fast sequential operations. After bit operations, a definite sequence of zeros or ones is obtained, which is similar to the use of an electronic mechanism to quickly operate a huge abacus. The bit of a digital computer is in a definite state of zero or one, but actual physics is continuous. There exists a significant deficiency in using digital Turing machines to describe the physical world. On the other hand, quantum physics happens to be discontinuous, and, thus, quantum Turing machines are truly compatible with problems in the quantum world.

      Abstract: It has been demonstrated that the photonic quantum computer is significantly faster than conventional supercomputers and that the practical quantum computer is one of the most promising ways to solve real-life problems. In this article, the development of photonic quantum computers and their potential applications are summarized, and three types of photonic quantum computing machines are detailed, including photonic quantum machines, coherent Ising machines (CIMs), and programmable photonic quantum computers. The photonic quantum industry, together with some start-up companies in associated application fields, are profiled. Compared with superconducting and ion traps, photonic quantum computing has its own advantages and disadvantages. It will be seen whether photonic quantum computer companies can capture a share of the future quantum computing market. The major challenges lie in the scalability of photonic systems and their adaptation and integration with silicon (Si) systems.

  • Superconducting and Silicon-Based Semiconductor Quantum Computers: A
           review

    • Free pre-print version: Loading...

      Abstract: Quantum computers are based on the theory of quantum mechanics, and their powerful parallel data processing capability is expected to solve many mathematical problems that too are difficult to be handled by classical computers. Especially with the increase of data processing volume, the quantum advantage is more obvious. Among the many physical systems for quantum computers, superconducting quantum circuit and semiconductor quantum dot computers show amazing potential due to their compatibility with traditional integrated circuit process technology and ultrashort gating time of nanoseconds. Superconducting qubits consisting of Josephson junctions and superconducting coplanar capacitors are easily integrated into a large scale for their simple circuit structure and conventional semiconductor process compatibility. Semiconductor qubits made from isotopically purified silicon (Si)-based materials greatly suppress nuclear spin noise, and decoherence times of ultralong milliseconds can be achieved. In this article, we systematically describe the challenges faced by superconducting qubits and semiconductor qubits in hot issues such as error correction and decoherence and look into the future development of superconducting quantum computers and Si-based semiconductor quantum computers.

      Abstract: An array of trapped atomic ions that are laser cooled and isolated in an ultrahigh-vacuum environment presents one of the most advanced physical platforms for realizing a practical quantum computer. Small-scale ion quantum computers up to tens of ions have been built and achieved the highest fidelities on elementary quantum operations and overall quantum volume (QV). This article provides an overview of the elements of trapped-ion quantum computing (TIQC), current achievements in the field, and future perspectives.

      Abstract: Quantum computing has gained enormous attention from both academia and industry for its capability in handling problems that challenge the limit of classical computation. It is expected to shine in areas such as artificial intelligence, financial technology, drug development, and chemical reaction modeling. The quantum bit, or qubit, is the essential unit of quantum computers (QCs), and there are different types of implementations of the qubit, such as superconductor-based qubits, trapped ion qubits, quantum dot qubits, photonic qubits, topological qubits, and nitrogen vacancy (NV) diamond qubits, which are known to be able to function at room temperature with high longevity. In this article, NV-centered diamond fabrication, qubit structure, bit control, entanglement, and decoherence, as well as the pros and cons, are briefly introduced. At the end, the status of the commercialization of NV diamond QCs and the benchmark of different types of qubits are summarized.
