Difficulty in maintaining the quantum state of subatomic particles is a major challenge in developing quantum computers. Princeton researchers have managed to maintain quantum data through use of diamonds infused with two carbon atoms per every silicon atom. These ‘flawed’ diamonds ‘could serve as quantum repeaters for networks based on qubits’ just as current networking systems have repeaters to keep signals strong between sender and receiver.
Renowned researcher, Pan Jianwei, lead a team of physicists from the University of Science and Technology of China with others from Alibaba’s Quantum Computing Laboratory. The research demonstrated entanglement of 6 photons, creating 18 qubits. The entanglements exploited three degrees of freedom encompassing their polarization, orbital angular momentum, and path. This nearly doubles the previous record of 10 entangled qubits.
The University of Adelaide is reporting the ability to fire one billion electrons per second using quantum mechanics; repeatedly. This is a major step to “reliable, continuous, and consistent” electron flow using quantum mechanics, a ‘must have’ for quantum computing. Clicking image takes you to schematic’s abstract.
Dubai Electricity and Water Authority is the first non-U.S. organization to take Microsoft up on its quantum program. The two aim to accelerate the water authority’s goals. Specifically, the organization’s ability to optimize energy use.
What do you call an object that is not quite quantum-sized and not quite ordinary-sized? Try a “Schrodinger’s kitten”. How does the world of quantum transform into the classical world? What does this look like? Here’s some deep thoughts…
University of Queensland researchers concluded an experiment bringing the path to quantum supremacy that much closer. And “The real message of this experiment is to not fear…researchers will have a more complete picture of boson sampling with loss, allowing them to forge new paths to a demonstration of quantum supremacy.”
Tokyo Institute of Technology researchers have matched theory to observation and thus have achieved a “comprehensive understanding of the coherent control of coherent optical phonons.” The usefulness of which is geared toward quantum computing memory systems as well as materials science and superconductivity.
The Australian research team at the U. of Melbourne has simulated a 60-qubit quantum computer. Estimations for the algorithm given it to process would require
A Russian research group at the Moscow Institute of Physics and Technology has demonstrated a superconductor feature known as Abrikosov vortices exists in non-superconducting metal when in contact with a superconductor. The nexus for quantum computers and this finding lays in the key property of superconductors: Quantum coherence. This “macroscopic quantum coherence of superconductors” may be harnessed to enable qubits.
