Quantum cryptography: Public key distribution and coin tossing

• No basis givenFindingBob obtains meaningful data from only half the photons he detects-those for which he guessed the correct polarization basis.Argued in the text, but no source is cited.§ lll. Quantum Public Key Distribution · p. 4 · argued, not cited
• No basis givenFindingAny such measurement yielding b bits of expected information (b ≤ 1/2) must induce a disagreement with probability at least b/2 if the measured photon, or an attempted forgery of it, is later re-measured in its original basis.Argued in the text, but no source is cited.§ lll. Quantum Public Key Distribution · p. 4 · argued, not cited
• No basis givenFindingThe optimum tradeoff occurs when the eavesdropper measures and retransmits all intercepted photons in the rectilinear basis, thereby learning the correct polarizations of half the photons and inducing disagreements in 1/4 of those later re-measured in the original basis.Argued in the text, but no source is cited.§ lll. Quantum Public Key Distribution · p. 4 · argued, not cited
• Not checked yetPremiseCloning a single photon into identically polarized photons is inconsistent with the foundations of quantum mechanics.None of the sources cited for this claim have been checked yet.§ II. Essential Properties of Polarized Photons · p. 3 · cites sources
• Own interpretationInterpretationEven in the presence of active eavesdropping, two parties can still distribute key securely if they share some secret information initially, provided the eavesdropping is not so active as to suppress communications completely.A conclusion the paper draws from its own results. There is no outside source to check it against.§ I. Introduction · p. 2 · no basis stated
• No basis givenPremiseTransmitted photons, in passing through a β polarizer, emerge with exactly β polarization, having lost all memory of their previous polarization α.Stated without a citation or an argument.§ II. Essential Properties of Polarized Photons · p. 3 · no basis stated
• Own interpretationInterpretationThe paper's coin-tossing protocol by exchange of quantum messages is secure against traditional kinds of cheating, even by an opponent with unlimited computing power.A conclusion the paper draws from its own results. There is no outside source to check it against.§ QUANTUM CRYPTOGRAPHY: PUBLIC KEY DISTRIBUTION AND COIN TOSSING · p. 2 · no basis stated
• No basis givenPremiseIf a light beam with polarization axis α is sent into a filter oriented at angle β, individual photons are transmitted with probability cos^2(α-β) and absorbed with complementary probability sin^2(α-β).Stated without a citation or an argument.§ II. Essential Properties of Polarized Photons · p. 2 · no basis stated
• Own interpretationInterpretationAn eavesdropper cannot even gain partial information about such a transmission without altering it in a random and uncontrollable way likely to be detected by the legitimate users.A conclusion the paper draws from its own results. There is no outside source to check it against.§ I. Introduction · p. 2 · argued, not cited
• Own interpretationInterpretationExcept where otherwise noted, the protocols are provably secure even against an opponent with superior technology and unlimited computing power, barring fundamental violations of accepted physical laws.A conclusion the paper draws from its own results. There is no outside source to check it against.§ I. Introduction · p. 2 · no basis stated
