Optimizing compilation of error correction codes for 2xN quantum dot arrays and its NP-hardness

Anthony Micciche, Feroz Ahmed Mian, Anasua Chatterjee +2

The ability to physically move qubits within a register allows the design of hardware-specific error-correction codes, which can achieve fault-tolerance while respecting other cons…

Fast readout of quantum dot spin qubits via Andreev spins

Michèle Jakob, Katharina Laubscher, Patrick Del Vecchio +3

Spin qubits in semiconducting quantum dots are currently limited by slow readout processes, which are orders of magnitude slower than gate operations. In contrast, Andreev spin qub…

Automated in situ optimization and disorder mitigation in a quantum device

Jacob Benestad, Torbjørn Rasmussen, Bertram Brovang +9

We investigate automated in situ optimization of the potential landscape in a quantum point contact device, using a gate array patterned atop the constriction. Optimiz…
