A Ge/Si heterostructure nanowire-based double quantum dot with integrated charge sensor

Summary by Nature
One proposal for a solid-state-based quantum bit (qubit) is to control coupled electron spins on adjacent semiconductor quantum dots1,2. Most experiments have focused on quantum dots made from III–V semiconductors; however, the coherence of electron spins in these materials is limited by hyperfine interactions with nuclear spins3,4,5,6. Ge/Si core/shell nanowires seem ideally suited to overcome this limitation, because the most abundant nuclei i…

MATH Seminar: “Universal blind measurement-based quantum computations”, Selman İpek, 5:30PM April 2 2025 (EN)

You are cordially invited to the Quantum Computing Seminar organized by the Department of Mathematics. Speaker: Selman İpek (Bilkent University) “Universal blind measurement-based quantum computations” Abstract: We consider a scenario in which a client (Alice) with limited computational power wishes to perform universal quantum computations via a server (Bob) without revealing their underlying computation. In this talk we discuss an interactive …
