Charge-noise tolerant exchange gates of singlet-triplet qubits in asymmetric double quantum dots
Tuukka Hiltunen, Hendrik Bluhm, Sebastian Mehl +1
In the semi-conductor double quantum dot singlet-triplet qubit architecture, the decoherence caused by the qubit's charge environment poses a serious obstacle in the way towards la…
Fault-Tolerant Quantum Computation for Singlet-Triplet Qubits with Leakage Errors
Sebastian Mehl, Hendrik Bluhm, David P. DiVincenzo
We describe and analyze leakage errors of singlet-triplet qubits. Even though leakage errors are a natural problem for spin qubits encoded using quantum dot arrays, they have obtai…
Two-Qubit Pulse Gate for the Three-Electron Double Quantum Dot Qubit
Sebastian Mehl
The three-electron configuration of gate-defined double quantum dots encodes a promising qubit for quantum information processing. I propose a two-qubit entangling gate using a pul…
Inverted Singlet-Triplet Qubit Coded on a Two-Electron Double Quantum Dot
Sebastian Mehl, David P. DiVincenzo
The spin configuration of two electrons confined at a double quantum dot (DQD) encodes the singlet-triplet qubit (STQ). We introduce the inverted STQ (ISTQ) that emerges fr…
Two-Qubit Couplings of Singlet-Triplet Qubits Mediated by One Quantum State
Sebastian Mehl, Hendrik Bluhm, David P. DiVincenzo
We describe high-fidelity entangling gates between singlet-triplet qubits (STQs) which are coupled via one quantum state (QS). The QS can be provided by a quantum dot itself or by…
