New type of quantum computer studies the dance of elementary particles




The standard model of particle physics is our best theory of the elementary particles and forces that make up our world: particles and antiparticles, such as electrons and positrons, are described as quantum fields. They interact through other force-fields, such as the electromagnetic force that binds charged particles.

To understand the behaviour of these quantum fields and with that our universe, researchers perform complex computer simulations of quantum field theories. Unfortunately, many of these calculations are too complicated for even our best supercomputers and pose great challenges for quantum computers as well, leaving many pressing questions unanswered.

Using a novel type of quantum computer, Martin Ringbauer’s experimental team at the University of Innsbruck, and the theory group led by Christine Muschik at IQC at the University of Waterloo, Canada report in a publication in the journal Nature Physics how they have successfully simulated a complete quantum field theory in more than one spatial dimension.

A natural representation of quantum fields

The crux that makes simulations of quantum field theories challenging for quantum computers comes from the need to capture the fields that represent the forces between particles, such as the electromagnetic force between charged particles. These fields can point in different directions and have different degrees of strength or excitations. Such objects do not neatly fit into the traditional binary computing paradigm based on zeros and ones, which is the basis of today's classical and quantum computers.

The new advance was possible through the combination of a qudit quantum computer developed in Innsbruck, and a qudit algorithm to simulate fundamental particle interactions developed in Waterloo. This approach is based on using up to five values per quantum information carrier, rather than just zero and one, to efficiently store and process information. Such a quantum computer is ideally suited to the challenge of representing complex quantum fields in particle physics calculations. “Our approach enables a natural representation of the quantum fields, which makes the computations much more efficient,” explains Michael Meth, lead author of the study. This enabled the team to observe the fundamental features of quantum electrodynamics in two spatial dimensions.

Huge potential for particle physics

Already in 2016, the creation of particle-antiparticle pairs was demonstrated in Innsbruck. “In that demonstration, we simplified the problem by restricting the particles to move on a line. Removing this restriction is a critical step to use quantum computers to understand fundamental particle interactions,” says Christine Muschik. Now the teams have presented the first quantum simulation in two spatial dimensions, “In addition to the behaviour of particles, we now also see magnetic fields between them, which can only exist if particles are not restricted to move on a line and bring us an important step closer to studying nature,” explains Martin Ringbauer.

The new work on quantum electrodynamics is just the beginning. With only a few qudits more it will be possible to extend the current results not only to three-dimensional models, but also to the strong nuclear force, which holds atoms together and contains many of physics’ remaining mysteries. “We are excited about the potential of quantum computers to contribute to the study of these fascinating questions,” says Ringbauer enthusiastically.

The research was financially supported among others by the Austrian Science Fund (FWF), the Austrian Federal Ministry of Education, Science and Research, the Austrian Research Promotion Agency (FFG), the European Union, and the Canada First Research Excellence Fund.

Physicists observe a new form of magnetism for the first time

MIT physicists have demonstrated a new form of magnetism that could one day be harnessed to build faster, denser, and less power-hungry " spintronic " memory chips. The new magnetic state is a mash-up of two main forms of magnetism: the ferromagnetism of everyday fridge magnets and compass needles, and antiferromagnetism, in which materials have magnetic properties at the microscale yet are not macroscopically magnetized. Now, the MIT team has demonstrated a new form of magnetism , termed "p-wave magnetism." Physicists have long observed that electrons of atoms in regular ferromagnets share the same orientation of "spin," like so many tiny compasses pointing in the same direction. This spin alignment generates a magnetic field, which gives a ferromagnet its inherent magnetism. Electrons belonging to magnetic atoms in an antiferromagnet also have spin, although these spins alternate, with electrons orbiting neighboring atoms aligning their spins antiparalle...

Green comet to pass Earth, won't be back for another 50,000 years

   visit:  https://hep-conferences.sciencefather.com/ After travelling from the icy reaches of our Solar System it will come closest to the Sun on January 12 and pass nearest to Earth on February 1.   A newly discovered comet could be visible to the naked eye as it shoots past Earth and the Sun in the coming weeks for the first time in 50,000 years, astronomers have said. The comet is called C/2022 E3 (ZTF) after the Zwicky Transient Facility, which first spotted it passing Jupiter in March last year. After travelling from the icy reaches of our Solar System it will come closest to the Sun on January 12 and pass nearest to Earth on February 1. It will be easy to spot with a good pair of binoculars and likely even with the naked eye, provided the sky is not too illuminated by city lights or the Moon. The comet "will be brightest when it is closest to the Earth", Thomas Prince, a physics professor at the California Institute of Technology who works at the Zwicky Transi...

"Explore the Fourth Dimension"

Fourth Dimension   The fourth dimension is a fascinating concept that has captured the imaginations of scientists, mathematicians, and artists for centuries. Unlike our three-dimensional world, which is limited by the linear flow of time, the fourth dimension is a realm of space and time that exists beyond our everyday experience. One way to visualize the fourth dimension is through the use of a hypercube, also known as a tesseract. A hypercube is a cube within a cube, with additional lines and edges connecting the vertices of the two cubes. It's impossible to construct in our three-dimensional world, but it provides a glimpse into what the fourth dimension might look like. Another way to understand the fourth dimension is through the concept of a wormhole, a theoretical passage through space-time that connects two distant points in the universe. A wormhole is like a shortcut through the fabric of space-time, allowing us to travel vast distances in an instant. While there is no de...
