3 days ago · Photonic quantum computing is a branch of quantum computing that utilizes photons (particles of light) as the basic unit of information, called qubits, instead of traditional electronic bits. In this paradigm, information is encoded in the quantum properties of photons, such as their polarization, phase, or path.
Aug 20, 2024 · This book is suitable as a course textbook or for independent study. The text begins with a significant overview of classical computing, from how they add numbers to their computational limits, and it mirrors many of the quantum computing topics that are covered later.
2 days ago · This book draft is an introduction to the logic of partitions on a set as well as the (quantum) logic of partitions (direct-sum decompositions or DSDs) on a vector space. Partitions of a set are categorically dual to subsets of a set.
Aug 23, 2024 · The paper [10] based on my lectures contains a review of algebraic and geometric approaches to quantum theory. This chapter mostly follows the same presentation. All sections include reprinted material from that review, which is openly available.
Aug 23, 2024 · At a high level, there are a few tenets of quantum computing that differentiate it from classical computation: qubits versus bits, quantum versus classical logic gates, the presence of quantum phenomena, and the opportunities offered by quantum computing’s enhanced computational capabilities.
1 day ago · Quantum computing. Quantum System One, a quantum computer by IBM from 2019 with 20 superconducting qubits [1] A quantum computer is a computer that exploits quantum mechanical phenomena. On small scales, physical matter exhibits properties of both particles and waves, and quantum computing leverages this behavior using specialized hardware.

6 days ago · In his book The Mathematical Foundations of Quantum Mechanics, published in 1932, von Neumann performed an analysis of the consequences of introducing hidden parameters (hidden variables) into quantum mechanics. He arrived at two principal conclusions: first, hidden variables cannot be incorporated into the existing theory of quantum mechanics ...
