Maximal tripartite entanglement between singlet-triplet qubits in quantum dots
Tuukka Hiltunen, Ari Harju
Singlet-triplet states in double quantum dots are promising realizations of qubits, and capacitive coupling can be used to create entanglement between these qubits. We propose an e…

Non-adiabatic charge state transitions in singlet-triplet qubits
Tuukka Hiltunen, Juha Ritala, Topi Siro +1
In double quantum dot singlet-triplet qubits, the exchange interaction is used in both quantum gate operation and the measurement of the state of the qubit. The exchange can be con…

Lagrange mesh and exact diagonalization for numerical study of semiconductor quantum dot systems with application in singlet-triplet qubits
Tuukka Hiltunen, Juha Ritala, Oona Kupiainen +2
We present a highly flexible computational scheme for studying correlated electrons confined by an arbitrary external potential in two-dimensional semiconductor quantum dots. The m…
