Quantum Mechanical Phenomena
Rigetti, D-Wave, IBM, Intel, and Google, have achieved milestones toward a quantum computer which performs computations incapable of being performed by classical systems.
Intel ~10 Years; Microsoft ~5 Years; IBM ~5 Years
Intel is one of the forerunners in the race to quantum supremacy. Alongside Microsoft, IBM, and Google, Intel hopes to press on to success with its silicon-based quantum processors.
Packets of Energy; Subtractable, Indivisible
Teams at the University of Southern Denmark, Arhaus University, and the University of Maryland’s Joint Quantum Institute have demonstrated the ability to subtract a photon of light from a laser beam. A unique property of light is its non-interaction with other photons as they pass through one-another. This property benefits quantum communication with high-success rates of transmission over long distances with encoded data.
Simply Put, a Primer
Superposition. Entanglement. Qubit. Absolute-zero. Decoherence. For the layperson, these terms may be remotely familiar or not-at-all. In any case, take a look at this quantum primer with its embedded clips. A good primer or just a fresh reminder of this relatively new technology and its language.
Einstein’s Spooky Action at a Distance… Wrong?
Is Einstein’s concept of spooky action at a distance in jeopardy of being proven false?
Tangle Lake, Alaska
What does Tangle Lake, Alaska, have in common with quantum computing? Intel named its 49-qubit processor “Tangle Lake”. Frigid conditions, an ‘entangled appearance’ from above; the similarities end there. Recently, Intel published an infographic explaining the components of this qubit processor. Visually interesting and a concise description of this 3×3 inch chip.
Quantum Information Storage
Scientists at Rice University have built on their experience with binding photons and excitons as evidenced in a 2016 report on their accomplishments. This has translated into more recent research in which the weak and strong link between these two has been found to be tunable. In this report, details are presented which allude to the ability to create quantum-based data storage.
Quantum Key Distribution Takes a Sizeable Step
Twin-field quantum key distribution (TF-QKD) has been publicly announced by a team of scientists from Toshiba Research in the U.K. Seeking to extend the range of QKDs with an improvement in bandwidth. Simply, a quantum repeater is placed between two communicating parties. Both parties send their code to the repeater which then relays measurements of the entangled signals.
Quantum Random Number Generation Excels
Quantum Random Number Generation Excels U.S. Government’s NIST organization will be adding to publicly available quantum-system generated products in the near future. The organization’s random number generator is deemed “fail safe”. How? The two entangled photons used to create the randomness are created then measured faster than light can travel. The timing of the measurement […]
IBM selects the Aussies…
IBM selects the Aussies… University of Sydney’s leadership in quantum computing, exemplified by recent advances in quieting a quantum system’s hardware, has learnt the helping in IBM choosing the Q-CTRL group to join Big Blue’s Q-Network. Amongst other startups such as Strangeworks, Q-CTRL hopes to gain access to the world’s most advanced quantum computing systems […]
