International quantum computing experts available to discuss Google’s quantum computing announcement


Expert Pitch

Newswise — Inès Montaño, an expert in physics and quantum computing, and Bertrand Cambou, an expert in cybersecurity and the use of quantum computing and microelectronics in security, are available to discuss Google’s announcement regarding quantum supremacy. Both are professors at Northern Arizona University.

Inès Montaño, associate professor, applied physics and materials science, Center for Materials Interfaces in Research and Applications (¡MIRA!); (928) 523-0418; ines.montano@nau.edu

Montaño worked for Sandia National Laboratories for more than a decade on a variety of projects including quantum computing and qubits with phosphorus donors in silicon, as well as novel nanoscale devices such as quantum lasers to engineered materials such as hyperbolic metamaterials. At NAU, she researches quantum photonics and anything related to quantum phenomena.

  • “Even though the result is impressive, it really is not a proof for quantum supremacy and does not even satisfy the lower conditions for quantum advantage.”
  • “The field is clearly moving in the right direction and now more than ever the need to tackle important problems such as how to build quantum repeaters and finally a quantum Internet is obvious.”

Bertrand Cambou, professor, nanotechnology and cybersecurity, School of Informatics, Computing, and Cyber Systems; (928) 523-7824; bertrand.cambou@nau.edu

Cambou’s primary research interests are in the use of nanoelectronics to strengthen cryptographic systems, including the design of novel components based on nanomaterials that are quantum computing resistant. His area of research includes securing blockchain technology, public key infrastructures, password managers and development of post-quantum resistant architectures. He is the author or co-author of more than 50 patents, is a senior member of the National Academy of Inventors and is an invention ambassador for the American Association for the Advancement of Science.

  • “The Google announcement is pure PR. Their quantum computer uses only 54 qubits, which has limited capabilities. To break cryptographic codes, we need 3,000 qubits, so they are far from what is needed.”
  • “Google error-correcting codes are perhaps better than what their peers are doing; this should be enough for some limited, but very important applications. The progress made by Google is impressive and in a very important technology of the future.”
