    • Quantum Computing Transmon Qubits Quantum Computing

      Transmon Qubits 101

      Transmon qubits are a type of superconducting qubit designed to mitigate charge noise by shunting a Josephson junction with a large capacitor. In other words, a transmon is a superconducting charge qubit that has reduced sensitivity to charge fluctuations​. The device consists of a Josephson junction (a nonlinear superconducting element) in parallel with a sizable capacitance, which increases the ratio of Josephson energy to charging…

      Adiabatic Quantum Computing (AQC) and Impact on Cyber

      Adiabatic Quantum Computing (AQC), and its variant Quantum Annealing, are another model for quantum computation. It's a specialized subset of quantum computing focused on solving optimization problems by finding the minimum (or maximum) of a given function over a set of possible solutions. For problems that can be presented as optimization problems, such as 3-SAT problem, quantum database search problem, and yes, the factoring problem…

    • Quantum Computing Quantum Random Circuit Sampling (RCS)

      Random Circuit Sampling (RCS) Benchmark

      At its core, Random Circuit Sampling (RCS) is a way to test how well a quantum computer can generate the output of a complex quantum circuit. Compare the results to what an ideal quantum computer should produce. If the quantum computer’s output closely matches the theoretical expectations, it demonstrates that the system is performing quantum operations correctly.

    • Quantum Computing Schrödinger Wave Equation

      Schrödinger’s Wave Equation

      Schrödinger’s equation is essentially the master instruction set for quantum systems – the quantum-world analogue of Newton’s famous F=ma in classical physics. In short, Schrödinger’s equation is to quantum mechanics what Newton’s second law is to classical mechanics: a fundamental law of motion describing how a physical system will change over time. It was formulated in 1925–26 by Erwin Schrödinger, who built on the idea…
