Enterprise Fellowships to kick-start the quantum technology industry
Posted by Karen Hurst in categories: business, cybercrime/malcode, energy, engineering, finance, health, internet, quantum physics, robotics/AI
Luv this.
The University of Bristol’s Quantum Technology Enterprise Centre (QTEC) is looking to recruit its first cohort of Enterprise Fellows that will be the next generation of quantum technology entrepreneurs.
Merging training in systems thinking, quantum engineering and entrepreneurship, QTEC will provide the necessary skills for budding innovators to develop their own business ideas and for them to branch out into the emerging field of quantum technologies.
The Centre, which is the first of its kind in the world, was funded as part of the UK’s £270 million investment into quantum technologies. These technologies exploit the laws of quantum mechanics to create practical and useful technologies that will outperform their classical rivals and that have the potential to transform artificial intelligence, healthcare, energy, finance, cyber security and the internet.

Unconventional quasiparticles predicted in conventional crystals
Posted by Karen Hurst in categories: particle physics, quantum physics
Another reason why we must look at all avenues of progress in Quantum. This particular discovery enriches many areas of material enrichment, QC (communications and information processing), etc. Limiting QC to only alerts from Google or maybe 1 other vendor is truly a mistake.
An international team of researchers has predicted the existence of several previously unknown types of quantum particles in materials. The particles — which belong to the class of particles known as fermions — can be distinguished by several intrinsic properties, such as their responses to applied magnetic and electric fields. In several cases, fermions in the interior of the material show their presence on the surface via the appearance of electron states called Fermi arcs, which link the different types of fermion states in the material’s bulk.
The research, published online this week in the journal Science, was conducted by a team at Princeton University in collaboration with researchers at the Donostia International Physics Center (DIPC) in Spain and the Max Planck Institute for Chemical Physics of Solids in Germany. The investigators propose that many of the materials hosting the new types of fermions are “protected metals,” which are metals that do not allow, in most circumstances, an insulating state to develop. This research represents the newest avenue in the physics of “topological materials,” an area of science that has already fundamentally changed the way researchers see and interpret states of matter.
The team at Princeton included Barry Bradlyn and Jennifer Cano, both associate research scholars at the Princeton Center for Theoretical Science; Zhijun Wang, a postdoctoral research associate in the Department of Physics, Robert Cava, the Russell Wellman Moore Professor of Chemistry; and B. Andrei Bernevig, associate professor of physics. The research team also included Maia Vergniory, a postdoctoral research fellow at DIPC, and Claudia Felser, a professor of physics and chemistry and director of the Max Planck Institute for Chemical Physics of Solids.

Researchers make leap in measuring quantum states
Posted by Karen Hurst in categories: computing, quantum physics
Another major leap forward in controlling system noise in QC.
A breakthrough into the full characterisation of quantum states has been published today as a Editors’ Suggestion in the journal Physical Review Letters.
The full characterisation (tomography) of quantum states is a necessity for future quantum computing. However, standard techniques are inadequate for the large quantum bit-strings necessary in full scale quantum computers.

World’s most powerful quantum computer now online at USC
Posted by Karen Hurst in categories: computing, information science, quantum physics, robotics/AI
Good for USC.
Following a recent upgrade, the USC-Lockheed Martin Quantum Computing Center (QCC) based at the USC Information Sciences Institute (ISI) is now the leader in quantum processing capacity.
With the upgrade — to 1,098 qubits from 512 — the D-Wave 2X™ processor is enabling QCC researchers to continue their efforts to close the gap between academic research in quantum computation and real-world critical problems.

Carbon Nanospheres Overcome Electron Spin Decoherence
Posted by Karen Hurst in categories: computing, quantum physics
Another spin on spin in QC.
Monitoring electron spins for a prolonged time period poses to be a major barrier in quantum computing. Scientists from EPFL have discovered the possibility of carbon nanospheres to overcome such barriers, even at room temperature.

One of the First Real-World Quantum Computer Applications Was Just Realized
Posted by Karen Hurst in categories: computing, engineering, quantum physics
Luv it; and this is only the beginning too.
In the continued effort to make a viable quantum computer, scientists assert that they have made the first scalable quantum simulation of a molecule.

Here’s How Google Is Racing to Protect You From Quantum Hackers
Posted by Karen Hurst in categories: computing, encryption, quantum physics
This is a true question especially since China launches their new Quantum Satellite communications in the next few weeks. I do believe some will be protected; however, the broader majority will be a stretch.
The encryption of today will be broken by the computers of tomorrow, even retroactively.

New device lengthens the life of quantum information
Posted by Karen Hurst in category: quantum physics
Yale University scientists have reached a milestone in their efforts to extend the durability and dependability of quantum information.
For the first time, researchers at Yale have crossed the “break even” point in preserving a bit of quantum information for longer than the lifetime of its constituent parts. They have created a novel system to encode, spot errors, decode, and correct errors in a quantum bit, also known as a “qubit.” The development of such a robust method of Quantum Error Correction (QEC) has been one of the biggest remaining hurdles in quantum computation.
The findings were published online July 20 in the journal Nature.
