Topological superconducting crystal PtBi₂ pairs up in 6-fold symmetric pattern; only top and bottom surfaces become superconducting

"persists even if crystal sliced/ reshaped... 6 directions along surface where electrons refuse to pair... naturally traps stable/ environmentally noise resistant Majorana particles (split electrons) along edges... step edges created, producing/ controlling these particles... fault-tolerant qubits... future: devise ways to manipulate the material, such as thinning it or applying magnetic fields, to isolate these quantum effects for use in future quantum computers"
