Abstract: This master's thesis investigates the ground state hyperfine levels coherence time in Pr3+:Y2Si05• This property is important for the future development of quantum computers based on this or similar crystals.A suitable method to measure the coherence time at liquid helium temperature for two hyperfine levels in the 4 H3 level of Pr3+ was developed and the coherence time has also been determined approximately to 540 J.l-S.Examensarbetet undersoker koherenstiden for tva hyperfin nivaer i grundtillstandet for Pr3+:Y2Si05 .Detta ar en egenskap som ar viktig for en framtida kvantdator baserad pa denna eller liknande kristaller.En metod att mata koherenstiden vid flytande helium temperatur for tva av hyperfinnivaerna i grundtillstandet for Pr3+ har utvecklats och koherenstiden har med denna metod matts upp till 540 J.l-S.
