TL;DR: A two-qubit logic gate is presented, which uses single spins in isotopically enriched silicon and is realized by performing single- and two- qubits operations in a quantum dot system using the exchange interaction, as envisaged in the Loss–DiVincenzo proposal.

TL;DR: This work combines the best aspects of both spin qubit schemes and demonstrate a gate-addressable quantum dot qubit in isotopically engineered silicon with a control fidelity of 99.6%, consistent with that required for fault-tolerant quantum computing.

TL;DR: An architecture for a silicon-based quantum computer processor based on complementary metal-oxide-semiconductor (CMOS) technology featuring a spin qubit surface code and individual qubit control via floating memory gate electrodes is proposed.

TL;DR: This work indicates that a spin-based quantum computer could be operated at increased temperatures in a simple pumped 4 He system (which provides cooling power orders of magnitude higher than that of dilution refrigerators), thus potentially enabling the integration of classical control electronics with the qubit array.

TL;DR: In this article, the authors propose an architecture for a silicon-based quantum computer processor based on complementary metal-oxide-semiconductor (CMOS) technology, and show how a transistor-based control circuit together with charge-storage electrodes can be used to operate a dense and scalable two-dimensional qubit system.
