The journal Quantum Information and Computation (QIC) made its debut last month. Most papers published in this field currently appear in the Los Alamos electronic preprint archives, and in a handful of journals in the physics, mathematics, and computer sciences arenas, says Hoi-Kwong Lo, one of the new journal’s managing editors and the chief scientist at MagiQ Technologies Inc in New York City. “It is getting difficult to keep track of all those papers and distinguish the good ones from the bad ones. We hope to bring a diverse community together and broaden the perspectives of researchers.” The first issue of QIC, which will appear every two months, focuses on quantum entanglement.
Quantum computing (QC) has already entered the industrial landscape and several multinational corporations have initiated their own research efforts. So far, many of these efforts have been focusing on superconducting qubits, whose industrial progress is currently way ahead of all other qubit implementations. This paper briefly reviews the progress made on the silicon-based QC platform, which is highly promising to meet the scale-up challenges by leveraging the semiconductor industry. We look at different types of qubits, the advantages of silicon, and techniques for qubit manipulation in the solid state. Finally, we discuss the possibility of co-integrating silicon qubits with FET-based, cooled front-end electronics, and review the device physics of MOSFETs at deep cryogenic temperatures.
