a, b SEM images of two cells with sizes (a) Lx ≃ 3 μm, and (b) Lx ≃ 1 μm. c Magnetic field modulation of the critical current in a readout junction on the Lx = 1 μm cell in the vortex free state, V = 0. d–f Ic(H) modulations for the Lx = 3 μm cell: (d) in the vortex-free state, V = 0, (e) with a trapped vortex, V = 1, and (f) with an antivortex V = −1. Blue and red symbols in d–f show simultaneously measured Ic for both readout JJs.
