Ampere-Maxwell's Law: Problem-Solving

629
A parallel-plate capacitor with capacitance C, whose plates have area A and separation distance d, is connected to a resistor R and a battery of voltage V. The current starts to flow at t = 0. What is the displacement current between the capacitor plates at time t? From the properties of the capacitor, what is the corresponding real current?
To solve the problem, we can use the equations from the analysis of an RC circuit and Maxwell's version of Ampère's law.
For the first part of...

    Area of Science:

    • Quantum Information Science
    • Integrated Photonics
    • Quantum Computing

    Background:

    • Linear optical quantum computing (LOQC) leverages robust technology and flexible conditions, aligning with DiVincenzo's criteria.
    • Integrated photonics enables gate-based quantum computing using path-encoded qubits and Mach-Zehnder interferometers (MZIs).
    • Post-selected controlled-Z (CZ) gates are resource-efficient for universal two-qubit operations but lack regular structure and cascadability, hindering scalability.

    Purpose of the Study:

    • To develop a universal and scalable LOQC approach on integrated photonic platforms.
    • To overcome limitations of existing post-selected CZ gates for large-scale quantum computation.
    • To demonstrate the feasibility of generating entangled states using the proposed scalable architecture.

    Main Methods:

    • Extended path-encoded dual-rail qubits to a triplet of waveguides, including an auxiliary waveguide.
    • Introduced a swap photonic network to map qubit structures for the post-selected CZ gate.
    • Developed an optical swap gate for non-nearest neighbor qubit interactions and demonstrated cascading of CZ gates.

    Main Results:

    • A novel, regularly structured path-encoded qubit suitable for scalable integrated photonics.
    • Demonstrated deterministic qubit location exchange and controlled quantum gates between arbitrary path-encoded qubits.
    • Successfully implemented cascading of post-selected CZ gates by truncating auxiliary waveguides.
    • Showcased Bell and Greenberger-Horne-Zeilinger (GHZ) state generation circuits utilizing the regular structure, cascading, and optical swap.

    Conclusions:

    • The proposed approach enables universal and scalable LOQC on integrated photonic platforms.
    • The developed methods overcome the structural and cascading limitations of previous LOQC implementations.
    • This work paves the way for building larger and more complex photonic quantum computers.
