Introduction to quantum networks

Envelope ✉️
Wojciech Kozlowski
The vision of a quantum internet is to enhance existing Internet technology by enabling quantum communication between any two points on Earth. Such a quantum internet will—in synergy with the “classical” internet that we have today—connect quantum information processors in order to achieve unparalleled capabilities that are provably impossible by using only classical information, such as distributing encryption keys secured by the laws of quantum mechanics, more efficient distributed agreement, or private delegated quantum computation. The first quantum entanglement networks have been realised in a lab including a software and network protocol stack for executing platform-independent applications. In this workshop we will introduce the basic concepts underpinning the quantum internet and take you through developing your own quantum network application running on a (for now) simulated quantum internet using the Quantum Network Explorer platform.
This workshop consists of two parts; First, a basic introduction to quantum networks. Here, I will introduce the basic building blocks of a quantum internet: quantum bits (qubits), entanglement, and quantum repeaters. I will then explain quantum mechanical phenomena enable greater security for communication and how entanglement is a fundamentally new resource for distributed tasks and computation. Secondly, to illustrate these concepts, I will take the audience through an implementation of a simple Quantum Key Distribution (QKD) application whereby Alice and Bob create a quantum-secured secret key which they can use to encrypt their communication. This will be done in Python using the tools available on the Quantum Network Explorer.

What do big tech, synthesizers, the crucifixion and Matthäus Passion have in common? Find the answer in the tech performance The Silicon Passion. We’ve all embraced big tech —but is it a warm hug or a strangulation? Bear witness to a debate of biblical proportions between tech nerds, technology and its users. In The Silicon Passion SETUP, in collaboration with de Transmissie (David Schwarz en Derk Stenvers) and Rodrigo Ferreira, is looking for a way out of the pit that technology has ...

Lightning talks are a 5 to 10 minute quick talk on an interesting subject. They can be with or without slides, and with or without proper preparation. if you weren't accepted in the main CfP, this is also a great opportunity to give an abridged version of your talk. These sessions will be available to sign up to later on, with details on the wiki: https://wiki.mch2022.org/Static:Lightning_Talks

This is a submission for a keynote talk at MCH2022. The Internet is both a familiar, comfortable place as well as a bottomless rabbit hole you can lose yourself in. The Internet has always been like this from its inception, the difference now is the scale and consequences are almost immeasurable - and it tests the limits of human imagination. When you look into the mirror of the Internet what you see reflected back depends on what you are looking for. It has become largely a reflection of ...

Have you ever forgotten a passphrase or lost a hardware token? Lost access to enough Bitcoin to buy a pizza or two? Encryption is fundamental to securing our liberties, but key and password management remain difficult even for professionals, let alone the general public. This talk presents Passcrow, an Open Source project attempting to address one of crypto's largest usability issues: password and key recovery in a decentralized environment.

Thanks to DNSSEC and DANE, it is possible to automatically verify user@domain.name identities by checking with domain.name servers. The real problem however, is integration with existing protocols, instead of inventing something completely new and perhaps web-only. The purpose of our work on Realm Crossover mechanisms has been to design generic solutions that extend many different application protocols, without changing their protocol specs.
