Quantum sensing with silicon chips

Exploiting the inherent fragility of quantum systems to develop advanced sensors for weak electric and magnetic fields.

Competitive advantage

• First in the world to demonstrate a quantum bit in silicon, using the spin of a single atom, introduced in the chip via an industry-standard technology
• Record-holder for quantum memory time, which translates into a record sensitivity toperturbing electromagnetic fields
• International collaboration to develop novel methods for extracting the maximum information
• on the environment of the atom
• Extension of world-leading silicon-based quantum computer technology to demonstrate quantum sensors integrated within a silicon nanoelectronic device
