Introduction to quantum cryptography - Vadim Makarov

I introduce the basic principles of quantum cryptography, and discuss today's status of its technology, with examples of optical schemes and components. No prior knowledge of quantum mechanics is required :).
This first lecture is about the basics of quantum cryptography. Lectures 2 and 3 cover quantum hacking:
• Quantum hacking - Vadi...
• Quantum hacking - Vadi...

Vadim Makarov is a research assistant professor at the Institute for Quantum Computing, heading the Quantum hacking lab - www.vad1.com/lab/
This course was part of a lecture series hosted by CryptoWorks21 in August 2014 in Waterloo, Canada.

Ой, какой же русский акцент..
Не, мне-то наоборот всё понятно, но вот англоязычным, наверное, тяжело.

[@TheDOTKU]

I need the class on how to build the equipment.

[@rigoluna1491]

You and me both

[@evoltar5409]

Great explanation in the beginning

SLLLAYYYEERRRRRRRRR

[@GenericPurpleTurtle]

Brilliant lecture, would love to see the second part!

[@osamaali3748]

Thanks

[@golnazafshar963]

Really helpful for my semiconductor exam
I do appreciate

[@quantumhacker8990]

if Alice is not sharing the bit information with Bob but only the chosen basis for a particular number of photons, then how Bob concludes the retained bit sequence by itself? if you say that it is Universal for bit value 1 for horizontal and 0 for rest of the polarization then it is possible for Eve to masquerade like Alice!? Still, it is not clear that what information Alice share with bob after 1000 photon transmission in your example! -retained bit? again how Bob knows whether its retained bits are with the lowest 'error' rates?

[@devonrusinek5807]

How do Alice and Bob determine the secure key without Eve eavesdropping on their method for determining the secure key?

[@vivipi3690]

Very good information.
Much appreciated.

thanks

It seems to me you're trying to make it too complex. Take two identical dictionaries give every defined word a number than use a system with say! with 10,000 or 10,000,000 single individual digit. Give every number or word its own individual digit after that your options are almost endless.

Awesome.... sir.. thank you

[@SeniorShinaganins]

Thanks

Hello, can any natural-English-speaker tell me, please, if this accent ok? Is it understandable/distractive? I think, as Russian, I have similar one..

[@toofan123]

I am not a native English speaker, But live in the UK for a very long time. It is totally understandable.

[@TheSharkasmCrew]

I've taken part in a few Makarov lectures - I find his accent a little difficult to follow, but it could certainly be far, FAR worse.

[@asper000]

Looks like he speaks English much less than writes/reads. Nerd-cryptohacker, keke.

[@seanki98]

I'm a native, the accent is thick but it is very clear and understandable
