I'm a graduate student that just finished a first course on quantum computation. I've also done a graduate-level course in (classical) cryptography.

I'm interested in Quantum Cryptography and would like to know what people would consider the most important papers for me to read if I want to get an intro to QC, for someone of my background. Any help would be much appreciated.

    $\begingroup$ Are you interested in quantum key distribution? Post-quantum cryptography? Zero-knowledge quantum proofs? Homomorphic quantum encryption? Or other areas of quantum cryptography? $\endgroup$ Apr 20 '21 at 15:20
  • $\begingroup$ Quantum key distribution mostly. $\endgroup$

For an interesting starting paper, that nearly was never a paper see Stephen Wisener's paper on Conjugate Coding. This paper started off things like the BB 84. The paper is paywalled though, and a typewritten copy (with typos too,), as it was written sometime in the 60s or 70s is an interesting read, to start, or to get a historical perspective.

    $\begingroup$ This is a paper that the OP probably should read, but it is nowhere near adequate for "getting an intro to QC". $\endgroup$ Jun 27 '21 at 13:43

" I've also done a graduate-level course in (classical) cryptography. I'm interested in Quantum Cryptography and would like to know what people would consider the most important papers for me to read if I want to get an intro to QC, for someone of my background."

You would first need to learn the very basics of quantum computing, and the simplest quantum computing algorithms such as the one to solve the Deutsch problem and it's more general version called the Deutsch-Jozsa problem. For the Deustch problem and the Deutsch-Jozsa problem, the seminal papers are as follows:

One of the simplest and earliest papers in the field of "quantum cryptography" is the BB84 paper, for which I've provided a link to the PDF below, because an HTML version doesn't seem to exist:

However, I think you will find it much easier if you were to just read about the above topics (basics of quantum computing, Deutsch/Deutsch-Jozsa problems and how they're solved more efficiently on quantum computers than classical computers, and the BB84 protocol) in an introduction textbook on quantum computing, such as the one by Nielsen and Chuang.

Otherwise you're going to be reading papers that were written with notation and typesetting that isn't the same as how it's been presented in the last two decades, and you'll have to put far more effort into your journey towards learning quantum cryptography since those papers were primary research articles (not didactic introductory textbooks).
