In this introduction to quantum consciousness, Justin Riddle presents six arguments that quantum consciousness is an important theory of mind.\
\
To summarize them briefly, People always identify as their latest technology and so most people believe that they are a digital computer. Time to update those models of self, because… Quantum computers are here. We wouldn’t want the brick of metal in our pocket to have greater computational power than our brain. People say the brain is too warm, wet, and noisy for quantum effects; yet, evidence keeps emerging for quantum effects in biology (such as photosynthesis). Where do we draw the line? Evolution might be selecting for quantum systems that can maintain quantum coherence. The debate around the role of quantum mechanics in consciousness has been raging for 100 years. Many key historical figures like Bohr, Schrodinger, Heisenberg, von Neumann entertained the idea that quantum mechanics might relate to our mind. Physical theories that are purely deterministic have failed to account for key aspects of subjective experience. There may be novel answers from a perspective that incorporate new physics.\

Entanglement is a property of quantum physics that is manifested when two or more systems interact in such a way that their quantum states cannot be described independently. In the terminology of quantum physics, they are said to be entangled, i.e. strongly correlated. Entanglement is of paramount importance to quantum computing. The greater the entanglement, the more optimized and efficient the quantum computer.
A study conducted by researchers affiliated with the Department of Physics at São Paulo State University’s Institute of Geosciences and Exact Sciences (IGCE-UNESP) in Rio Claro, Brazil, tested a novel method of quantifying entanglement and the conditions for its maximization. Applications include optimizing the construction of a quantum computer.
An article on the study is published as a letter in Physical Review B.
For a while researchers thought they’d have to make do with noisy, error-prone systems, at least in the near term. That’s starting to change.
EV batteries tend to lose range capacity over their lifetime, but Volkswagen-backed startup PowerCo says it tested one from California-based QuantumScape that ‘practically does not age.’
KENNEWICK — The LIGO Hanford Observatory near Richland is expected to detect 60% more cataclysmic cosmic events — like colliding neutron stars and black holes — thanks to a quantum limit breakthrough.
Since the observatory was turned back on in May after three years of upgrades, including adding new quantum squeezing technology, it can probe a larger volume of the universe.
“Now that we have surpassed this quantum limit, we can do a lot more astronomy,” said Lee McCuller, assistant professor of physics at the California Institute of Technology and a leader in the study published in the journal “Physical Review X.”
A quarter century ago, physicist Juan Maldacena proposed the AdS/CFT correspondence, an intriguing holographic connection between gravity in a three-dimensional universe and quantum physics on the universe’s two-dimensional boundary. This correspondence is at this stage, even a quarter century after Maldacena’s discovery, just a conjecture.
A statement about the nature of the universe that seems to be true, but one that has not yet been proven to actually reflect the reality that we live in. And what’s more, it only has limited utility and application to the real universe.
Still, even the mere appearance of the correspondence is more than suggestive. It’s telling that there is something deeply fundamental to the hologram, that the physics of the volume of the universe might just translate to the physics on the surface, and that there is more to be learned there.
The US is trying its best to slow China down.
However, an equally serious challenger has now emerged in the form of SEIDA, a Chinese startup founded by a veteran Silicon Valley software executive.
Liguo “Recoo” Zhang, the CEO of SEIDA, and three other Chinese-born colleagues left Siemens EDA, a U.S. unit of Siemens AG, aiming to break the foreign monopoly on Optical Proximity Correction (OPC) technology, reported Reuters.
The OPC tool is indispensable for designing advanced chips crucial for emerging technologies like artificial intelligence and quantum computing. SEIDA’s bold pitch attracted powerful Chinese investors, including Semiconductor Manufacturing International Corp (SMIC), a leading Chinese microchip maker with alleged ties to China’s military.
