Özet:

 

Due to nontrivial orbital pairing symmetry, surfaces and  interfaces of high-Tc superconductors support states which violate  time-reversal (T-) symmetry.  Such naturally degenerate states,  useful as working states of a qubit, are standard for atomic or  molecular-size qubit prototypes (e.g. based on nuclear spins), but  exceptional for mesoscopic qubits.  (In particular, they hold promise  of a better scalability.)  In these lectures I review the physics of  T-breaking on surfaces and interfaces of high-Tc  superconductors; then describe existing proposals for high-Tc based  qubits and the current state of experiments; finally, I discuss the  decoherence sources in the system, open questions, and future research  directions.
