Quantum Sensing

Researchers are exploring the potential to detect gravitons using quantum sensing technologies in hope of linking quantum mechanics with Einstein’s theory of relativity.

Advanced quantum sensing tools, such as those used at LIGO, detect gravitational waves by overcoming quantum noise through techniques like “squeezing.” These tools could also support graviton detection by providing a more precise way to measure gravitational disturbances in lab environments.

While technical and philosophical challenges remain, progress in quantum sensing may narrow the gap between quantum mechanics and gravitational theory, and provide new insights into phenomena like black holes and the Big Bang.

While each tasked with the important role of numerically explaining our reality, gravity and quantum mechanics tend to mix like oil and water — they have long presented a profound challenge to unify in the domain of physics. Albert Einstein’s general theory of relativity, established in 1915, describes gravity as the curvature of space-time. In contrast, quantum mechanics suggests that forces are mediated by particles.   READ MORE...

Brain Fibers & Quantum Entanglement

Most scientists have resisted the concept that quantum physics plays any role in the brain — an environment that Physicist Max Tegmark argued would be “too wet, warm and noisy” for quantum mechanics to play a meaningful role in cognition or consciousness..

However, recent research from China suggests that quantum entanglement—a phenomenon Albert Einstein famously dubbed “spooky action at a distance”—might play a role in the synchronization of neurons in the human brain, according to a New Scientist article.

The study, peer-reviewed in Physical Review E and also referenced in the online pre-print server ArXiv, examine the potential mechanisms by which quantum entanglement could impact neural synchronization and cognition. While both studies propose innovative ideas, they acknowledge the speculative nature of their findings and emphasize the need for further empirical validation.       READ MORE...
