Quantum key distribution with imperfect devices
Kvantnyckeldistribution är ett alternativ till traditionella metoder för att distribuera krypteringsnycklar. Till skillnad från de traditionella metoderna är kvantnyckeldistribution säkert även mot kvantdatorer. Olika typer av fel i sändare och mottagares laboratorier kan dock påverka säkerheten hos systemet. Större och mer generella fel leder till sämre säkerhet. Information om nyckeln kan också With the rise of quantum computers that can break traditional key distribution protocols for cryptography, new methods are needed. In Quantum Key Distribution (QKD), quantum physics is used to create and distribute a secret key between honest parties. This thesis focuses on the well-known BB84 protocol. The sender (Alice) sends quantum states to the receiver (Bob) who measures the states. Alice’s

Semi-Supervised Approach For Sleep Scoring Using Wavelet Transformed EEG Data
Automatisk sömnklassificering med hjälp av artificiell intelligens. Sömn är avgörande för vår hälsa, men att manuellt analysera sömn är både tidskrävande och kostsamt. Genom att använda artificiell intelligens har vi utvecklat en metod som automatiskt kan klassificera sömnstadier baserat på EEG-signaler, vilket kan effektivisera sömnanalys. Människor spenderar ungefär en tredjedel av sina liv sHistorically, sleep stage classification has relied on manual scoring performed by experienced professionals. In recent years, the emergence of machine learning has enabled the automation of this process, thus saving both time and resources. Many of these sleep staging models depend on data which already has been annotated by a professional, but a few try to exploit the vast amount of unlabelled d

Alternative production method of Psilocybin, bioreactor cultivation of Psilocybe Cubensis
Depression är ett stort problem i samhället idag, det vanligaste läkemedlet som används för behandling av det är någon typ av Selektiva serotoninåterupptagshämmare (SSRI). Dessa läkemedel är effektiva men kräver regelbundna doser och har otrevliga sidoeffekter såsom viktuppgång, emotionell avtrubbning och sexuell dysfunktion. Psilocybin har nyligen fått uppmärksamhet som ett alternativ till dessThe scientific interest in psilocybin has recently been reignited, the research community has once again begun to investigate the promising potential that psilocybin offers in the area off treatment of depression and PTSD. An obstacle to the research of psilocybin is that today pharmaceutical grade psilocybin is produced using an inefficient and thus costly synthetic process. This hampers the rese
Klimatnytta till salu? Den privata skogsägarens roll i den svenska koldioxidmarknaden
Så kan skogsägare bromsa klimatförändringarna – och samtidigt få betalt för det. Privata skogsägare kan spela en nyckelroll i Sveriges klimatarbete – men då krävs ersättning och tydligare regler. Klimatförändringarna har ökat behovet av lösningar som både minskar utsläpp och binder koldioxid. Skogen är en naturlig kolsänka – alltså ett ekosystem som lagrar koldioxid – och därför är skogsbruket i Since pre-industrial times, increased greenhouse gases in the atmosphere has contributed to climate change affecting all ecosystems. As a result, global and national commitments have been made to reduce emissions by enhancing the number and effectiveness of carbon sinks. To meet the national climate targets, Sweden has proposed financial compensation for forest owners who postpone harvesting. This
