Quantum mechanics of the ground state of four identical fermions

Posted by in categories: particle physics, quantum physics

Basically this was found out in the 1980s and this allows for teleportation in real life 😳 😅 🙃


Wave functions for four identical spin‐one‐half fermions with total spin 0 1, and 2 are constructed. Lower bounds on the ground state energies of these spin states are derived. The results are illustrated with an.

Magnetic monopoles in spin ice

Posted by in categories: particle physics, quantum physics

Circa 2008


A theoretical study proposes that magnetic monopoles may appear not as elementary but as emergent particles in complex, strongly-correlated magnetic systems such as spin ice, in analogy to fractional electric charges in quantum Hall systems. This theory explains a mysterious phase transition in spin ice that has been observed experimentally.

Particle seen switching between matter and antimatter at CERN

Posted by in categories: particle physics, quantum physics

A subatomic particle has been found to switch between matter and antimatter, according to Oxford physicists analyzing data from the Large Hadron Collider. It turns out that an unfathomably tiny weight difference between two particles could have saved the universe from annihilation soon after it began.

Antimatter is kind of the “evil twin” of normal matter, but it’s surprisingly similar – in fact, the only real difference is that antimatter has the opposite charge. That means that if ever a matter and antimatter particle come into contact, they will annihilate each other in a burst of energy.

To complicate things, some particles, such as photons, are actually their own antiparticles. Others have even been seen to exist as a weird mixture of both states at the same time, thanks to the quantum quirk of superposition (illustrated most famously through the thought experiment of Schrödinger’s cat.) That means that these particles actually oscillate between being matter and antimatter.

Mario animated using the supercooled atoms in a quantum computer

Posted by in categories: computing, particle physics, quantum physics

Physicists with the Harvard-MIT Center for Ultracold Atoms have just announced new success with a particular style of quantum computer —a “programmable quantum simulator”. In this architecture, they take supercold rubidium atoms and use optical tweezers (beams of light) to arrange the atoms into shapes.

As the Harvard Gazette writes 


This new system allows the atoms to be assembled in two-dimensional arrays of optical tweezers. This increases the achievable system size from 51 to 256 qubits. Using the tweezers, researchers can arrange the atoms in defect-free patterns and create programmable shapes like square, honeycomb, or triangular lattices to engineer different interactions between the qubits.

Consciousness & Information

Posted by in categories: computing, education, mobile phones, neuroscience, quantum physics

To use the metaphor of our Information Age, consciousness to humans is as Cloud to computers. Just like your smartphone, your brain is a ‘bio’-logical computing device of your mind, an interface for physical reality. Our minds are connected into the greater mind-network, as computers in the Cloud. Viewed in this way, consciousness is ‘non-local’ Cloud, our brain-mind systems are receivers, processors and transmitters of information within that Cloud. What were the most significant factors in evolution of the human mind? What’s the connection between quantum physics and consciousness? What role does quantum information play in our self-reflective consciousness? What is non-local consciousness? Do our minds create reality? These are some of the most salient questions addressed in this Part II of the documentary.

Nuclear Physicists Hunt for Clues of Color Transparency in Protons

Posted by in categories: particle physics, quantum physics

Protons populate the nucleus of every atom in the universe. Inside the nucleus, they cling tightly to neighboring protons and neutrons. However, it may be possible to knock out protons that are in a smaller size configuration, so that they interact less with nearby particles as they exit the nucleus. This phenomenon is called color transparency. Nuclear physicists hunting for signs of color transparency in protons recently came up empty handed.

The Impact.

The theory that describes the behavior of particles made of quarks is called quantum chromodynamics (QCD). QCD includes many common subatomic particles, such as protons and neutrons. It also predicts the phenomenon of color transparency. Physicists have observed color transparency in simpler, two-quark particles called pions. If physicists can observe or rule out color transparency for protons, a more complicated three-quark system, they would gain important clues regarding the differences between two-and three-quark systems in QCD.

Quantum supremacy has been achieved by a more complex quantum computer

Posted by in categories: computing, quantum physics

A quantum computer made by researchers in China has solved a calculation in 4.2 hours that would take a classical computer thousands of years. This demonstration of what the researchers call “quantum computational advantage” was made using 6 more qubits – quantum bits – than the computer used by the Google team that first demonstrated the feat in 2019.

Layered Graphene with a Twist Displays Unique Quantum Confinement Effects in 2-D

Posted by in categories: computing, particle physics, quantum physics

Understanding how electrons move in 2-D layered material systems could lead to advances in quantum computing and communication.

Scientists studying two different configurations of bilayer graphene —the two-dimensional (2-D), atom.

An atom is the smallest component of an element. It is made up of protons and neutrons within the nucleus, and electrons circling the nucleus.

Breaking the warp barrier for faster-than-light travel

Posted by in categories: information science, particle physics, quantum physics, space travel

If travel to distant stars within an individual’s lifetime is going to be possible, a means of faster-than-light propulsion will have to be found. To date, even recent research about superluminal (faster-than-light) transport based on Einstein’s theory of general relativity would require vast amounts of hypothetical particles and states of matter that have “exotic” physical properties such as negative energy density. This type of matter either cannot currently be found or cannot be manufactured in viable quantities. In contrast, new research carried out at the University of Göttingen gets around this problem by constructing a new class of hyper-fast ‘solitons’ using sources with only positive energies that can enable travel at any speed. This reignites debate about the possibility of faster-than-light travel based on conventional physics. The research is published in the journal Classical and Quantum Gravity.

The author of the paper, Dr Erik Lentz, analysed existing research and discovered gaps in previous ‘warp drive’ studies. Lentz noticed that there existed yet-to-be explored configurations of space-time curvature organized into ‘solitons’ that have the potential to solve the puzzle while being physically viable. A soliton — in this context also informally referred to as a ‘warp bubble’ — is a compact wave that maintains its shape and moves at constant velocity. Lentz derived the Einstein equations for unexplored soliton configurations (where the space-time metric’s shift vector components obey a hyperbolic relation), finding that the altered space-time geometries could be formed in a way that worked even with conventional energy sources. In essence, the new method uses the very structure of space and time arranged in a soliton to provide a solution to faster-than-light travel, which — unlike other research — would only need sources with positive energy densities.
