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 …

Nov 22, 2020 · A qubit has, theoretically, an infinite number of possible states. And, theoretically, each state could represent a different piece of data. And, just like the above, any finite amount …

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 …

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 …

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.

Jan 16, 2018 · Hello everyone, I don't know how to measure the QBER of BB84 protocol in a realistic experiment.In the most paper show the data which is only the number but do not show …

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, …

Sep 17, 2015 · In this abstraction, the controlled gate has no effect on the control qubit. You can even measure the control qubit before or after it is used as a control, without changing the …

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 …

Sep 9, 2015 · The Planck length is an extremely small distance constructed from physical constants. Many misconceptions generally overstate its physical significance, stating that it’s …
