• While each of its main theories works extraordinarily well, they clash also with each other – leaving physicists to search for a deeper, more fundamental theory.
• But do we really need a theory of everything?
• Our two best theories of nature are quantum mechanics and general relativity, describing the smallest and biggest scales of the universe, respectively.
• If it could, it would indicate that quantum theory might ultimately be more fundamental than general relativity, accounting for four out of five forces – suggesting general relativity ultimately may need to be modified.
• If it couldn’t, that would shake up physics – suggesting we may need to modify quantum mechanics, too.

What about other mysterious properties?

• And what about other mysterious properties such as dark energy, which causes the universe to expand at an accelerated rate, or dark matter, an invisible substance making up most of the matter in the universe?
• “Dark matter and dark energy are most of the matter energy content in the universe.
• So it’s not really a theory of everything if it’s not accounting for most of the matter energy content in the universe,” she argues.
• “One of the strengths that people will point to with string theory is that string theory built on quantum field theory,” explains Prescod-Weinstein.

• A team of researchers with the IllinoisExpress Quantum Network (IEQNET) have successfully deployed a long-distance quantum network between two U.S. Department of Energy laboratories using local fiber optics.
• They showed that it is possible for quantum and classical signals to coexist across the same network fiber and achieve synchronization, both in metropolitan-scale distances and real-world conditions.
• When classical computers need to execute synchronized operations and functions, like those required for security, they rely on network time protocol.
• Such precision will allow scientists to accurately identify and manipulate entangled photon pairs for supporting quantum network operations over metropolitan distances in real-world conditions.

• LOS ANGELES, May 19, 2022 /PRNewswire/ --Unitary Fund, a 501(c)(3) non-profit helping create a quantum technology ecosystem that benefits the most people, has released Metriq, a platform for hosting and sharing community-driven Quantum Benchmarks.
• Metriq's mission is to make transparent, accessible benchmarks available to everyone in the quantum computing community.
• Unitary Fund is a 501(c)(3) non-profit whose mission is to create a quantum technology ecosystem that benefits the people around the world.
• Through our microgrant program, we fund an inclusive community of explorers across the world to work on quantum technologies.

• Experts in quantum science and technology from around the globe will gather on November 4, both virtually and in person in Chicago, for the fourth annual Chicago Quantum Summit .
• The Chicago Quantum Exchange was the first multiple-institution hub, led by the University of Chicago, for quantum information innovation, said Bohr Quantum Technologies Chairman and CEO Paul Dabbar, a keynote speaker at the summit who is also a former U.S. undersecretary of energy for science.
• Building a vibrant quantum ecosystem requires a diverse, quantum-ready workforce and practical pathways to commercializing technologies, says Chicago Quantum Exchange Director David Awschalom.
• Learn more about the speakers, view the agenda, and register for the online event on the 2021 Chicago Quantum Summit website.
