How Does a Qubit Exist as Both 1 and 0 Simultaneously? I think 10 more IQ points would help me understand quantum physics at the level I'd like That said, I'd like to know more about Qbits I've watched several videos about them, and they say that they can be 1 and 0 at the same time Is that just an analogy to the polarization of the old
Schrödingers Cat and the Qbit - Physics Forums If, on the other hand, the cat is truly in a superposition of “alive” and “dead”, then we have a quantum bit of information (qubit or Qbit) Let explain the difference between a Cbit and a Qbit and let you decide
Information content of a qubit • Physics Forums I have just started reading Neilson and chuang's book on quantum computing and two times already have they said that when a qubit is not observed, it can contain infinite information "How much information is represented by a qubit? Paradoxically, there are an infinite number of points on the
Why Entangled Photon-Polarization Qubits Violate Bells Inequality per . . . Let me start by deriving the photon-polarization qubit probabilities using Information Invariance Continuity from the information-theoretic reconstruction of quantum mechanics, just as I did to derive the spin- qubit probabilities in this Insight, this paper, and “ Einstein’s Entanglement: Bell Inequalities, Relativity, and the Qubit
Quantum Physics Forum • Physics Forums Join in expert discussion on quantum physics Quantum physics is the mathematical description of the motion and interaction of subatomic particles Quantum Mechanics and Field Theory
What Planck Length Is and It’s Common Misconceptions The Planck length is an extremely small distance constructed from physical constants Many misconceptions generally overstate its physical significance, stating that it’s the inherent pixel size of the universe The Planck length does have physical significance, and I’ll discuss what it is and what it isn’t
How to understand quantum computers? • Physics Forums A single qubit can be a superposition of those two states But the magic comes when you have many entangled qubits So 10 bits will have one of 1024 states 10 qubits can be a superposition of any combination of those 1024 states - an enormous number A special case of quantum computing is the quantum annealing process
How Quantum Information Theory Solves “the only mystery” of Quantum . . . Our experimental context will be established by equally illuminating a pair of slits in phase with a laser of wavelength , then reducing the intensity of the laser until it is emitting one photon at a time (Figure 1); this is our quantum bit of information aka qubit (physical instantiation of 2-dim Hilbert space)
Quantum computer storage capacity - Physics Forums I have a question regarding the storage capacity of quantum computers I read that 32 qubits (4 "quantum bytes" if you will - not sure if that's an actual
Understanding Two-Qubit States: The Bell States - Physics Forums An example of a two-qubit state is one of the Bell states, for example: lB> = 1 √2 (l00> + l11>) In my book it is stated that the Bell states form an orthonormal basis for the set of two qubit states But what exactly is the general form of a two-qubit state? Is it any vector of the form: lq>
