      "summary_nl": "Quantum mechanica leert dat de miscroscopische fysische werkelijkheid radicaal anders is dan wat de macroscopische wereld suggereert. Dit heeft talrijke implicaties, ook in de cryptografie, de wetenschap van het beveiligen van informatie. Een quantum computer zou in principe zekere veel gebruikte encryptie systemen breken. Echter, encryptie gebaseerd op quantum-mechanische effecten kan aanvallen met de quantum computer weerstaan. Sinds de 80er jaren was dit laatste in essentie de enige constructieve cryptografische toepassing van quantum mechanica. Hierin kwam onlangs verandering met de introductie van een \"quantum bron\" waaraan cryptografische veiligheid ontleend wordt door de praktische onhaalbaarheid van betrouwbaar opslaan van grote hoeveelheden quantum-toestanden. Een aantal methoden voor anonimiteit en privacy bescherming is gebaseerd op dit principe van beperkt quantum geheugen. Echter, het begrip van deze quantum bron is verre van volledig, en de methoden lijken sub-optimaal in de memory-bound. Het doel van dit project is twee-ledig. Het eerste doel is het ontwikkelen van nieuwe technieken in de quantum informatie-theorie die het mogelijk maken de memory-bound in deze veelbelovende methoden (hopelijk optimaal) te verbeteren. Voorts is het doel om nieuwe mogelijke quantum bronnen te bestuderen die nieuwe cryptografische systemen kunnen opleveren, o.a. door beperkingen in de aanvaller's coherent measurements of door gebruik te maken van ruis in quantum communicatie. Tevens zal een raamwerk ontwikkeld worden waarbinnen het mogelijk is om de veiligheid van quantum-cryptografische methoden te formalizeren wanneer deze in complexe omgevingen worden gebruikt; dit staat in contrast met de huidige praktijk, die alleen stand-alone security garandeert.",
