Dan dennett on patterns and ontology.

I want to look at what Dennett has to say about patterns because 1) I introduced the term in my previous discussion, In Search of Dennett’s Free-Floating Rationales [1], and 2) it is interesting for what it says about his philosophy generally.

You’ll recall that, in that earlier discussion, I pointed out talk of “free-floating rationales” (FFRs) was authorized by the presence of a certain state of affairs, a certain pattern of relationships among, in Dennett’s particular example, an adult bird, (vulnerable) chicks, and a predator. Does postulating talk of FFRs add anything to the pattern? Does it make anything more predictable? No. Those FFRs are entirely redundant upon the pattern that authorizes them. By Occam’s Razor, they’re unnecessary.

Oby, Degenhart, Grigsby and colleagues used a brain–computer interface to challenge monkeys to override their natural time courses of neural activity. They found the time courses to be highly robust, suggestive of network-level computational mechanisms.

Errors in quantum computers are an obstacle for their widespread use. But a team of scientists say that, by using an antimony atom and the Schrödinger’s Cat thought experiment, they could have found a way to stop them.

UK researchers used special optical tweezers to attain quantum entanglement of molecules that could unlock multiple applications in quantum computing.

Our data-driven world demands more—more capacity, more efficiency, more computing power. To meet society’s insatiable need for electronic speed, physicists have been pushing the burgeoning field of spintronics.

Traditional electronics use the charge of electrons to encode, store and transmit information. Spintronic devices utilize both the charge and spin-orientation of electrons. By assigning a value to electron spin (up=0 and down=1), spintronic devices offer ultra-fast, energy-efficient platforms.

To develop viable spintronics, physicists must understand the quantum properties within materials. One property, known as spin-torque, is crucial for the electrical manipulation of magnetization that’s required for the next generation of storage and processing technologies.

Pulsed laser deposition is used for the heteroepitaxial growth of methylammonium lead iodide (CH3NH3PbI3) thin films on a KCl substrate at room temperature. Experimental and computational results confirm cubic phase stabilization by tensile epitaxial strain in the CH3NH3PbI3 thin films.

Researchers have revolutionized quantum technology by achieving long-lasting entanglement between molecules using ‘magic-wavelength optical tweezers.’

This breakthrough enhances the potential for quantum computing.

Performing computation using quantum-mechanical phenomena such as superposition and entanglement.

IonQ fired the first shot in the M&A opportunities for quantum startups back in 2021, becoming the first publicly traded pure-play quantum computing company. In late 2024, IonQ filed to acquire Qubitekk as part of its strategy to apply distributed computer development as a means to progress toward a CRQC computer in data centers.

I predict that IonQ, among others in the space, has just begun its M&A program.

Harnessing molecular connections: unlocking long-lasting quantum entanglement.

Quantum entanglement—the mysterious connection that links particles no matter the distance between them—is a cornerstone for developing advanced technologies like quantum computing and precision measurement tools. While significant strides have been made in controlling simpler particles such as atoms, extending this control to more complex systems like molecules has remained challenging due to their intricate structures and sensitivity to their surroundings.

In a groundbreaking study, researchers have achieved long-lived quantum entanglement between pairs of ultracold polar molecules using a highly controlled environment known as “magic-wavelength optical tweezers.” These tweezers manipulate molecules with extraordinary precision, stabilizing their complex internal states, such as vibrations and rotations, while enabling detectable, fine-scale interactions.
