七个参考页面，涵盖各类量子机器及其周边领域，以各个层次的读者都能读懂的方式如实呈现。厂商说法均注明为厂商说法。
Quantum Computers
What a quantum computer actually is and how a computation runs, start to finish.
Qubits
Amplitudes, phase and the Bloch sphere. Why a qubit is not '0 and 1 at the same time'.
Hardware
The reference comparison of all seven modalities: principles, strengths, challenges, and who builds each.
Software & Algorithms
Shor, Grover, simulation and variational methods. What each does, why it matters, and a reality check.
Quantum Networking
Distributing entanglement: QKD, networked sensors, and the repeater problem.
Quantum Sensing
The nearer-term neighbor: precision measurement that doesn't need a million error-corrected qubits.
Quantum Security
Shor vs today's encryption, harvest-now-decrypt-later, and the NIST post-quantum standards.
How this hub is organized
Start with Quantum Computers for the machine itself and Qubits for the unit it computes with. Hardware is the reference centerpiece: the honest comparison of all seven ways people build qubits, connected to the company directory. Software & Algorithms covers what the machines would actually run. The last three pages (Networking, Sensing and Security) are the neighboring quantum fields, two of which are commercializing ahead of computing itself.
