Researchers make leap in measuring quantum states

Posted by 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 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 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.

Error fix for long-lived qubits brings quantum computers nearer

Posted by in categories: computing, quantum physics

For the first time, researchers are able to extend the lifetime of a quantum bit, or qubit, using error correction – an essential step to useful quantum computers.
