Novel protocols for estimating Hamiltonian parameters of a superconducting quantum processor could improve precision

Posted by in categories: quantum physics, robotics/AI

Researchers at Freie Universität Berlin, University of Maryland and NIST, Google AI, and Abu Dhabi set out to robustly estimate the free Hamiltonian parameters of bosonic excitations in a superconducting quantum simulator. The protocols they developed, outlined in a paper pre-published on arXiv, could contribute to the realization of highly precise quantum simulations that reach beyond the limits of classical computers.

Bridging The Gap: Consciousness, Mind Upload, and Quantum Theology

Posted by in categories: neuroscience, quantum physics

Before I begin, I would like to state that the topics discussed here in reference to Quantum Mechanics represent my own understanding of the science. These ideas may or may not fall in with those who have achieved accreditation for their own understanding of the subject matter. The observations of the author are derived from extensive study of the science from a variety of materials, including audio and visual lectures. It is my hope that the understanding presented here will offer a medium of sorts for those concerned with preservation of personality.

Innovative magnetic levitation: New material offers potential for unlocking gravity-free technology

Posted by in categories: materials, quantum physics

Researchers at the Quantum Machines Unit at the Okinawa Institute of Science and Technology (OIST) are studying levitating materials – substances that can remain suspended in a stable position without any physical contact or mechanical support. The most common type of levitation occurs through magnetic fields. Objects such as superconductors or diamagnetic materials (materials repelled by a magnetic field) can be made to float above magnets to develop advanced sensors for various scientific and everyday uses.

Prof. Jason Twamley, head of the unit, and his team of OIST researchers and international collaborators, have designed a floating platform within a vacuum using graphite and magnets. Remarkably, this levitating platform operates without relying on external power sources and can assist in the development of ultra-sensitive sensors for highly precise and efficient measurements. Their results have been published in the journal Applied Physics Letters.

When an external magnetic field is applied to diamagnetic materials, these materials generate a magnetic field in the opposite direction, resulting in a repulsive force – they push away from the field. Therefore, objects made of diamagnetic materials can float above strong magnetic fields. For instance, in maglev trains, powerful superconducting magnets create a strong magnetic field with diamagnetic materials to achieve levitation, seemingly defying gravity.

Scientists use light to visualize magnetic domains in quantum materials

Posted by in categories: materials, quantum physics

When something draws us in like a magnet, we take a closer look. When magnets draw in physicists, they take a quantum look. Scientists from Osaka Metropolitan University and the University of Tokyo have successfully used light to visualize tiny magnetic regions, known as magnetic domains, in a specialized quantum material. Their study was published in Physical Review Letters.
