Caltech quantum-computation lecture notes, chapter 3.
Verified primary passages: sections 3.4.2–3.4.3, printed pp. 33–37, equations (3.125)–(3.132), unitary system-environment phase damping and spontaneous-emission amplitude damping. Diagonal populations are constant in the phase-damping example, but change in the amplitude-damping example while off-diagonal coherence is suppressed. Reuses the existing John Preskill and Work by John Preskill headers.
By Dan Israël. Master ICFP 2019–2020 lecture notes; front matter lists latest update 29 March 2022.
Verified primary text: section 5.2.3, printed pp. 118–120 (PDF pp. 120–122), equations (5.53), (5.57)–(5.60). The improved current has weight one at matter central charge 26. Its self-OPE retains higher-order poles; the simple-pole obstruction to nilpotence vanishes at criticality. The PDF text extraction loses derivatives in the simple-pole term; the wiki only reproduces the unambiguous higher-order terms and states residue cancellation.
Authored Quantum Mechanics IV lecture notes, title page dated 7 March 2011. Inspected printed pp. 23–26, equations 1.75–1.99: classical/fluctuation split, determinant ratio and harmonic-oscillator transition kernel. Upload path 2018 is not treated as the work date.
Original byline: Freddy Cachazo, Song He and Ellis Ye Yuan. Inspected section 2, equations 1–7, null external momenta and scattering equations; section 3, equations 8 and its projective gauge fixing. Section 6.2 relates the equations to high-energy string scattering.
Authored lecture notes, chapter 7. Inspected section 7.9.1, printed pp. 35–36, equations 7.117–7.120: stabilizer eigenspace and independent-generator dimension. Equation 7.160 gives the generator-product factorization of the stabilizer sum.
Proceedings of the Koninklijke Nederlandse Akademie van Wetenschappen 51, 793–795; communicated 29 May 1948. Original calculation of the ideal parallel-plate electromagnetic vacuum-energy interaction. The hosted scan includes the 1997 Academy reprint at pp. 61–63; 1997 is not the original publication date.
Official Physical Measurement Laboratory description of its quantum-network light sources. No personal author credited for the general introductory SPDC section.
Inspected section Spontaneous Parametric Down-Conversion and Figure 2: quadratic nonlinearity, pump conversion to paired photons, heralding and probabilistic preparation. Institution/work record already exists in chemistry-author.bigb; do not duplicate it.
American Journal of Physics 58, 731–734. Inspected original paper, received 30 March 1990 and accepted 28 April 1990; publication is August 1990.
Section III and equation (5) give the GHZ Pauli-product contradiction. The paper chooses the opposite three-qubit relative sign from the plus-GHZ state used in this wiki; the concept article explicitly calculates the signs for its own state.
Inspected original author preprint: section 1, printed pp. 2–5, defines edge qubits, commuting star/face checks, four-dimensional protected torus subspace and the gapped local Hamiltonian. The author byline is A. Yu. Kitaev. The displayed November 2024 TeX date is distinct from the arXiv submission date, 9 July 1997; it is not treated as a new publication.
Annalen der Physik 324(3), 487–553; doi:10.1002/andp.19063240303. Reproduced original German text; introductory discussion and electric/magnetic deflection analysis. Distinct from the shorter 1905 paper of the same title. Historical model comparisons are not presented as modern confirmation of his preferred model.
Nuclear Physics B307 (1988), 145; corrected complete version hep-th/9205070 (1992). The separately submitted hep-th/9205068 is the ERRATA, not the complete paper. Abstract: one-loop corrections to gauge-coupling relations in four-dimensional heterotic-string vacua.
Physical Review Letters 10, 531–533 (15 June 1963). Original paper on unitary-symmetry organization of weak leptonic decay amplitudes. Quark-current notation in the biography is explicitly a modern illustration, not attributed to the original 1963 notation.
Institut de Physique de Nice project description, Robin Kaiser PI; coherent transport, light localization, sample absorption and cold ytterbium clouds. These are research aims, not a claim that the targeted three-dimensional localization has been observed.
PDF contains original German appendix, English translation and distinct comments by D. Kriesell. Expectation-value dynamics inspected in translated original. Received date says 5 September 1927; do not repeat unreliable July-date metadata.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
