Quantum Technology Spins into Scalability

(LabNews) A multi-disciplinary *team has published proof-of-concept for a powerful and scalable quantum technology. The researchers have demonstrated that bottom-up chemical synthesis enables quantum information to be encoded directly into a molecules ‘spin’. This novel technique presents the ability to tailor-make quantum bits with unprecedented precision and control.
This new bottom-up approach could ultimately lead to quantum systems that have extraordinary flexibility and control, helping pave the way for next-generation quantum technology.
“Chemical synthesis enables atomistic control over qubit structure,” said Danna Freedman, professor of chemistry at Northwestern’s Weinberg College of Arts and Sciences. “Molecular chemistry creates a new paradigm for quantum information science.” She led the research along with her colleague David Awschalom at the University of Chicago’s Pritzker School of Molecular Engineering.
“This is a proof-of-concept of a powerful and scalable quantum technology,” said Awschalom, the Liew Family Professor in Molecular Engineering. “We can harness the techniques of molecular design to create new atomic-scale systems for quantum information science. Bringing these two communities together will broaden interest and has the potential to enhance quantum sensing and computation.”
