Carbon Nanospheres Overcome Electron Spin Decoherence

Posted by 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 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 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 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 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.

Precisely controlled levitation of nanodiamonds could bring advances in sensors, quantum information processing

Posted by in categories: nanotechnology, quantum physics

Researchers have demonstrated how to control the “electron spin” of a nanodiamond while it is levitated with lasers in a vacuum, an advance that could find applications in quantum information processing, sensors and studies into the fundamental physics of quantum mechanics.

Electrons can be thought of as having two distinct spin states, “up” or “down.” The researchers were able to detect and control the electron spin resonance, or its change from one state to the other.

Electron spin control: Levitated nanodiamond is research gem

Posted by in categories: nanotechnology, quantum physics

I’m telling folks there is much to be learn in the usage of natural and synthetic resources especially around diamonds — Nanodiamonds Magic.


WEST LAFAYETTE, Ind. — Researchers have demonstrated how to control the “electron spin” of a nanodiamond while it is levitated with lasers in a vacuum, an advance that could find applications in quantum information processing, sensors and studies into the fundamental physics of quantum mechanics.

Electrons can be thought of as having two distinct spin states, “up” or “down.” The researchers were able to detect and control the electron spin resonance, or its change from one state to the other.

Quantum computers show potential to revolutionize chemistry

Posted by in categories: chemistry, neuroscience, quantum physics, robotics/AI, solar power, supercomputing, sustainability

Like this feature on QC.


If you have trouble wrapping your mind around quantum physics, don’t worry — it’s even hard for supercomputers. The solution, according to researchers from Google, Harvard, Lawrence Berkeley National Laboratories and others? Why, use a quantum computer, of course. The team accurately predicted chemical reaction rates using a supercooled quantum circuit, a result that could lead to improved solar cells, batteries, flexible electronics and much more.

Chemical reactions are inherently quantum themselves — the team actually used a quote from Richard Feynman saying “nature isn’t classical, dammit.” The problem is that “molecular systems form highly entangled quantum superposition states, which require many classical computing resources in order to represent sufficiently high precision,” according to the Google Research blog. Computing the lowest energy state for propane, a relatively simple molecule, takes around ten days, for instance. That figure is required in order to get the reaction rate.
