The electric sector is undergoing rapid changes, growing in complexity, and continues to be extremely vulnerable to cyber-attacks, physical incidents, and existential threats. Last year, President Biden signed into law H.R.7535, the Quantum Computing Cybersecurity Preparedness Act,⁵ which encourages federal agencies to prepare for a quantum computing threat that could break today’s encryption keys. Adding to the complexity, new business models are emerging as larger portions of the economy, such as transportation, are electrified and intermittent resources and new energy storage solutions are developed and incorporated into the electric grid. Quantum Information Science (QIS) however does not only serve as a threat, but can also play a part in addressing both the grid’s vulnerabilities and the grid’s increasing complexity as the grid evolves to meet changing requirements and goals in the energy sector.
|
This qFACSS Topic Area will explore the following areas:
|
1. Quantum computing for optimization and contingency analysis;
|
2. Quantum key distribution (QKD) and post quantum cryptography (PQC) for grid
|
cybersecurity; and
|
3. Quantum sensing for grid timing and synchronization with DERs (redundancy, GPS synchronization, or GPS replacement), grid anomaly detection, positioning, navigation, and timing for mobile storage (EVs with vehicle-to-everything capability), CO₂ management (e.g. pipeline or generation plant leakage detection, hydrogen leakage detection, and CO₂ sequestration and CO₂ storage), and geothermal detection/imaging.
|
This Topic Area will involve a lab data call to inventory currently developed QIS technologies at the labs that could be leveraged for the grid as outlined above and described in more detail below.
|
In parallel, This Topic Area will facilitate a Request for Information (RFI), open to both industry and lab input, to gain a holistic understanding of the landscape of QIS technologies qualified will help inform ongoing partnerships and future RDD&D funding opportunities as well as this Lab Call Topic Area if timely. Meanwhile, relevant and discrete projects under the DOE V2X MO⁶

Note 18. Fair value measurements
|
Our financial assets and liabilities are summarized below as of June 30, 2023 and December 31, 2022, with fair values shown according to the fair value hierarchy (in millions). The carrying values of cash and cash equivalents, U.S. Treasury Bills, other receivables and accounts payable, accruals and other liabilities are considered to be reasonable estimates of or otherwise approximate the fair values.

We released the weights and code for these models under an open source licence¹¹. The comparison of our autoencoder with competitors can be found in Table 4.
