Limitations on the maximal level of entanglement of two singlet-triplet qubits in GaAs quantum dots
Igor Bragar, Łukasz Cywiński
We analyze in detail a procedure of entangling of two singlet-triplet (-) qubits operated in a regime when energy associated with the magnetic field gradient, , i…

Retardation of entanglement decay of two spin qubits by quantum measurements
Igor Bragar
We study a system of two electron spins each interacting with its small nuclear spin environment (NSE), which is a prototype system of two electron spin quantum dot (QD) qubits. We…
