TL;DR: The architecture of SymPy is presented, a description of its features, and a discussion of select domain specific submodules are discussed, to become the standard symbolic library for the scientific Python ecosystem.

TL;DR: In this paper, a silicon-germanium heterojunction bipolar transistor (HBT) was used for pre-amplification of a single electron transistor (SET) in liquid helium.

TL;DR: This work compares the performance of two cryogenic amplification circuits: a current-biased heterojunction bipolar transistor circuit (CB-HBT), and an AC-coupled HBT circuit (AC-H BT), and finds less than 10 μs is required for both circuits to achieve bit error rates below 10−3, which is a putative threshold for quantum error correction.

TL;DR: In this article, a silicon metal-oxide-semiconductor quantum dot architecture based on a single polysilicon gate stack is proposed, with two enhancement gates separated spatially by a gap, one gate forming a reservoir and the other a quantum dot.

TL;DR: In this paper, a double quantum dot spin qubit is shown to be all-electrically controlled without the need for any external components, like micromagnets, that could complicate integration.
