000154402 520__ $$aWe describe high-fidelity entangling gates between singlet-triplet qubits (STQs) which are coupled via onequantum state (QS). The QS can be provided by a quantum dot itself or by another confined system. Theorbital energies of the QS are tunable using an electric gate close to the QS, which changes the interactionsbetween the STQs independent of their single-qubit parameters. Short gating sequences exist for controlled NOT(CNOT) operations. We show that realistic quantum dot setups permit excellent entangling operations with gateinfidelities below 10−3, which is lower than the quantum error correction threshold of the surface code. Weconsider limitations from fabrication errors, hyperfine interactions, spin-orbit interactions, and charge noise inGaAs and Si heterostructures.
