Dec 7, 2007 · In 2001, all-optical quantum computing became feasible with the discovery that scalable quantum computing is possible using only single-photon sources, linear optical elements, and single-photon detectors.

Linear optical quantum computing or linear optics quantum computation (LOQC), also photonic quantum computing (PQC), is a paradigm of quantum computation, allowing (under certain conditions, described below) universal quantum computation.

In 2001 all-optical quantum computing became feasible with the discovery that scalable quantum computing is possible using only single photon sources, linear optical elements, and single photon detectors.

APL is developing an optical approach to quantum computing in which the bits, or “qubits,” are represented by single photons. Our approach allows the use of ordinary (linear) optical elements that are generally available as off-the-shelf components.

Jan 9, 2025 · Researchers in Japan recently developed an optical quantum computer that can be used for a variety of applications, a feature they say makes it the first general-purpose optical quantum computer in the world. While purpose-built optical quantum machines have been available for years, a general-purpose one has long been a goal of the industry.

This topic is divided into five subsections: Sect. 1.1 is the foreword; Sect. 1.2 introduces some representative quantum algorithms; Sect. 1.3 briefly describes the theoretical background of optical quantum computing; Sect. 1.4 focuses on the preparation of light quantum bits and coherent manipulation; Sect. 1.5 goes into the particulars of ...

In 2001, all-optical quantum computing became feasible with the discovery that scalable quantum required for universal quantum computation. The computing is possible using only single-photon sources, linear optical elements, and single-photon canonical example is …

Oct 9, 2023 · In this Perspective article, we provide a systematic explanation of why and how optics might be able to give speed or energy-efficiency benefits over electronics for computing, enumerating 11...

5 days ago · Our results epitomized the potential of the temporal-multiplexed optical system, which has found applications in coherent Ising machine (30–32), continuous-variable measurement–based quantum computing (33–36), and (Gaussian) boson sampling (37–39), in investigating exotic quantum correlations.
