Black holes are instrumental in the study of the unification of Quantum Mechanics and General Relativity because they are macroscopic quantum objects—essentially like large particles (which should give a clue that particles are small black holes). In a black hole construct one can study the effects of strong gravity and quantum field theory in a singular system, enabling one to understand both in a singular framework. This also means, however, that one needs a unified theory of quantum gravity to fully understand black holes (and other quantum systems). 

The thermodynamics and quantum information (or entropy) of a black hole are of key consideration, especially the relationship between the information comprising...

Euler's 36-Piece Puzzle has a Quantum Solution!

By Dr. Inés Urdaneta / Physicist at Resonance Science Foundation

What is this 240-year-old problem all about?

Leonhard Euler (1707 - 1783), Swiss mathematician and physicist, is most popularly known for his glorious equation called Euler's Identity: e + 1 = 0, depicted below.

Geometric interpretation of Euler's identity, where i represents the imaginary axis of the complex plane and φ is the angle.

Euler’s contributions in mathematics have been indispensable for the development of physics, particularly in quantum mechanics. As if that were not enough, now the quantum solution to Euler’s puzzle will probably mark a milestone in quantum computation, and in information theory. The puzzle as such consists of the following: Euler had examined the problem of having six different regiments, each with six officers of different ranks,  and he wondered if these 36 officers can be arranged in a 6x6 square, so that each row and column contains one officer of...

Experiment Shows Possibility of Using Multicellular Organism the Tardigrade in Probing Macroscopic Quantum States

Tardigrade revived after most inhospitable conditions yet documented for the meiofauna organism, setting a record for the conditions under which a complex form of life can survive.

By: William Brown, Biophysicist at the Resonance Science Foundation

A new study has claimed to have taken a tardigrade— a microscopic multicellular organism known to tolerate extreme physiochemical conditions via a latent state of life known as cryptobiosis—and prepared it in a type of superconducting Josephson junction known as a transmission line shunted plasma oscillation qubit, or transmon for short, causing the tardigrade (in the suspended cryptobiosis state) to purportedly become entangled in the qubit system.

Quantum Simulator Reveals New State of Matter Possible with Topological Spin Liquids

By Resonance Science Foundation biophysicist William Brown

Quantum spin liquids are exotic phases of matter that offer potential applications in robust quantum information processing with topological qubits. Quantum spin liquids are a phase of matter that feature long-range quantum entanglement involving the magnetic dipoles, or spin, of electrons. Unlike in conventional magnets where the magnetic dipoles of electrons all align and freeze into place, electrons in this new exotic phase are constantly changing and fluctuating like a liquid— leading to one of the most entangled states of matter ever conceived. 

Until recent investigations it was unknown if such a highly quantum correlated magnetic state could be realized in an actual physical system. Now, using a 219-atom programmable quantum simulator a team of Harvard researchers have shown that quantum matter and protected quantum information processing are possible with topological spin liquids. Their findings...

Does Spacetime Emerge From Entanglement?

By Dr. Inés Urdaneta / Physicist at Resonance Science Foundation

The question above could start with the following one: Is space an illusion?

Since the magnitude of a force like electromagnetic and gravity between two objects is inversely proportional to the distance between them, it seems plausible to conclude objects only interact with other objects when they are close, and the closer they are, the stronger the interaction. For instance, when bringing two magnets towards each other, one can feel the increase in the rejection between them (if approached by the same pole) or attraction between them (if opposite polarity). And since the force can be felt when the objects are still not in contact, one could say that the force is mediated by a field. Fields spread out as they propagate outside of the object.  

This dependence of forces and interactions upon distance is the main characteristic of the principle of locality. Locations and speeds of objects are defined...
