The Nine Billion Names Of God

Posted by in categories: information science, mathematics, particle physics, quantum physics

Quantum theory is strange and counterintuitive, but it’s very precise. Lots of analogies and broad concepts are presented in popular science trying to give an accurate description of quantum behavior, but if you really want to understand how quantum theory (or any other theory) works, you need to look at the mathematical details. It’s only the mathematics that shows us what’s truly going on.

Mathematically, a quantum object is described by a function of complex numbers governed by the Schrödinger equation. This function is known as the wavefunction, and it allows you to determine quantum behavior. The wavefunction represents the state of the system, which tells you the probability of various outcomes to a particular experiment (observation). To find the probability, you simply multiply the wavefunction by its complex conjugate. This is how quantum objects can have wavelike properties (the wavefunction) and particle properties (the probable outcome).

No, wait. Actually a quantum object is described by a mathematical quantity known as a matrix. As Werner Heisenberg showed, each type of quantity you could observe (position, momentum, energy) is represented by a matrix as well (known as an operator). By multiplying the operator and the quantum state matrix in a particular way, you get the probability of a particular outcome. The wavelike behavior is a result of the multiple connections between states within the matrix.

FUNCTION FOLLOWS FORM in the Quantum world, with a NEW splitting and pairing massless Black Hole

Posted by in categories: cosmology, quantum physics

Perfect for Halloween — the big Pumpkin Star story.


According to Quantum FFF Theory, stars are formed between dual new physics black holes called Herbig Haro pressure cookers.

The dual black holes can have different sizes and different capacities to produce different sized stars.

New Evidence for the Existence of Majorana Fermions Has Been Uncovered

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

In Brief:

  • 80 years after it was first theorized, researchers have found more evidence for the existence of a fermion that’s its own antiparticle.
  • The discovery of Majorana fermions could be the key to developing usable quantum computers.

Super-Cool Quantum Research Lab Heads to Space

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

Just WOW!


PULLMAN, Wash., Oct. 26 — Washington State University and NASA scientists are set to begin an investigation into the strange world of quantum physics on the International Space Station.

WSU physicists Peter Engels and Maren Mossman are part of a team studying the behavior of atoms laser-cooled to temperatures just a few billionths of a degree above absolute zero, the point where they behave like one wave of discrete particles.

Quantum Bit MRI Machine to See Shapes of Individual Biomolecules for Drug Research

Posted by in categories: biotech/medical, computing, particle physics, quantum physics

Drug discovery is a long and difficult process that requires a comprehensive understanding of the molecular structures of compounds under investigation. It’s difficult to have an idea of the precise shape of complex molecules such as proteins, but researchers at University of Melbourne in Australia have come up with a way of seeing the location of individual atoms within biomolecules.

Using quantum bits, most notably utilized in quantum computer research, the investigators offer a way of producing a magnetic resonance sensor and a magnetic field gradient that can work as a tiny MRI machine. The machine would have the resolution capable of seeing single atoms components of larger molecules. This MRI machine has yet to be actually built, but the steps have been laid out based on comprehensive theoretical work. If it proves successful in practice, the technology may overcome current imaging techniques that rely on statistical averages and don’t work well on molecules that don’t crystallize well.

“In a conventional MRI machine large magnets set up a field gradient in all three directions to create 3D images; in our system we use the natural magnetic properties of a single atomic qubit,” said lead author of the research Viktor Perunicic. “The system would be fabricated on-chip, and by carefully controlling the quantum state of the qubit probe as it interacts with the atoms in the target molecule, we can extract information about the positions of atoms by periodically measuring the qubit probe and thus create an image of the molecule’s structure.”

Precise quantum cloning: Possible pathway to secure communication

Posted by in categories: encryption, quantum physics

Physicists at The Australian National University (ANU) and University of Queensland (UQ) have produced near-perfect clones of quantum information using a new method to surpass previous cloning limits.

A global race is on to use quantum physics for ultra-secure encryption over long distances according to Prof Ping Koy Lam, node director of the ARC Centre of Excellence for Quantum Computation and Communication Technology (CQC2T) at ANU.
