We demonstrate rapid high-fidelity state preparation and measurement in exchange-only Si/SiGe triple-quantum-dot qubits. Fast measurement integration (980-ns) and initialization (approximately 300-ns) operations are performed with all-electrical base

Singlet-triplet spin states of a quantum dot support promising semiconductor-based qubits, yet often suffer from poor state preparation and measurement, due to low-lying excited states. Engineering a large energy splitting is impeded by the inability

Electrically defined silicon-based qubits are expected to show improved quantum memory characteristics in comparison with GaAs-based devices due to reduced hyperfine interactions with nuclear spins. Silicon-based qubit devices have proved more challe

Exploiting the weak interactions between electron spins and nuclear spins in silicon-based quantum dots leads to a dephasing time two orders of magnitude greater than in analogous gallium-arsenide-based devices, demonstrating the potential of silicon

We report on a quantum dot device design that combines the low disorder properties of undoped SiGe heterostructure materials with an overlapping gate stack in which each electrostatic gate has a dominant and unique function -- control of individual q

We demonstrate improved operation of exchange-coupled semiconductor quantum dots by substantially reducing the sensitivity of exchange operations to charge noise. The method involves biasing a double-dot symmetrically between the charge-state anti-cr

Three coupled quantum dots in isotopically purified silicon enable all-electrical qubit control with long coherence time.
Like modern microprocessors today, future processors of quantum information may be implemented using all-electrical control

We demonstrate double quantum dots fabricated in undoped Si/SiGe heterostructures relying on a double top-gated design. Charge sensing shows that we can reliably deplete these devices to zero charge occupancy. Measurements and simulations confirm tha
