Extended Data Fig. 4: Spin relaxation measurements using parity readout.
From: Operation of a silicon quantum processor unit cell above one kelvin
a–c, PZZ with |⇊⟩ initialization and flipping the spin of Q1 adiabatically via EDSR (|⇅⟩) (a), no spin flip (|⇊⟩) (b) and flipping the spin of Q2 adiabatically (|⇵⟩) (c). d–f, PZZ with S-like initialization and flipping the spin of Q1 adiabatically (d), no spin flip (e) and flipping the spin of Q2 adiabatically via EDSR (f). The measurements were performed at B0 = 1.4 T and TMC = 40 mK. Each data point is the average of 100 single shots, with three overall repeats, giving a total of 300 single shots. All fits are according to equations (9)–(14). The error range of T1 represents the 95% confidence level.
