  1. Finding E_J Value of a Qubit: Step-by-Step Guide - Physics Forums

    Mar 6, 2019 · The transition frequency of the qubit is given by $\sqrt{8EcEj} - Ec$. However, it's explicitly mentioned that it's an approximation. Is there any reference from which I can obtain …

  2. Quantum computer storage capacity - Physics Forums

    Aug 10, 2022 · A qubit is not a storage element, it is a noisy processor element that has a probability; 0 ≤ p ≤ 1. Each time you read a single qubit you will get only 0 or 1. Coupling …

  3. How can a quantum computer be faster than a classic computer?

    Feb 16, 2025 · From those articles, to read 1 qubit, we have to colapse its wave function (do I understand it right), and this qubit is fixed to 0 or 1. But then again, 1 qubit is equal to 1 bit …

  4. How to understand quantum computers? - Physics Forums

    Apr 4, 2025 · Quantum computers take advantage of entanglement. A single bit is in one of two states. A single qubit can be a superposition of those two states. But the magic comes when …

  5. Understanding Z2 Symmetry in Models - Physics Forums

    Feb 6, 2009 · Even simple, [itex]\mathbb{Z}_2[/itex] refers to a group, namely that of additon mod 2. It only has two elements, the identity and element a, which satisfies a^2 = 1.

  6. Molecular Quantum Computer Progress - Physics Forums

    Feb 6, 2025 · Trapping molecules to perform quantum operations. By carefully controlling how the molecules rotated with respect to one another, the team managed to entangle two molecules, …

  7. Quantum Physics Forum

    Apr 13, 2025 · Quantum physics, or quantum mechanics, is a branch of physics that explores the behavior of matter and energy at the smallest scales, where classical physics principles break …

  8. Question about quantum state distinguishability - Physics Forums

    Mar 21, 2025 · Let n be a natural number. Suppose you are given one of two n-qubit states, |ψ₀ or |ψ₁ , each equally likely (with probability 1/2). You know exactly what these two states are, but …

  9. Gauss' Law: Conductor, Insulator, Electric Field - Physics Forums

    Dec 7, 2024 · Homework Statement UNDONE Relevant Equations Charge or Electric Field Perhaps, Gauss's Law

  10. Density matrix for bell states - Physics Forums

    Mar 1, 2013 · A pure state can be a linear combination of other pure states. This is the quantum mechanical superposition. For a pure state |ψ> we simply chose this state |ψ> to construct the …
