“…Operation of the circuits with the phase shifting element based on frozen flux quanta [20] has been tested earlier in Ref. [21]. Here we present the first demonstration of the functioning of an SFS π-phase shifter integrated in a conventional Nb SFQ circuit.…”

“…It is anticipated that unconventional junctions either with a fixed phase shift ϕ 0 (ϕ-junctions), or with an in-built spatial phase variation along the junction ∆ϕ (0 − ϕ junctions) may provide additional functionality in Josephson electronics [1][2][3][4]. For example, they can operate as autonomous and persistent phase batteries -one of key elements of quantum [1,[5][6][7][8][9][10][11][12][13][14] and digital Josephson electronics [2,3,15,16]. Such junctions can be also used for development of novel types of cryogenic memory [17][18][19][20][21][22].…”

“…Similar phase shifters have been used for digital RSFQ electronics. 14 , 15 Recently it was shown that an Abrikosov vortex can induce a JPS in nearby JJs in the full [−2π, + 2π] range. 23 , 43 , 44 Since vortices can be easily manipulated (displaced, introduced, or removed) by magnetic field, H , 23 , 45 47 current, I , 20 , 48 , 49 and light, 50 , 51 they can be used for creation of memory cells 20 and tunable phase shifters.…”
