The Real Reasons Quantum Entanglement Doesn’t Allow Faster-Than-Light Communication
Posted by Karen Hurst in category: quantum physics
Orzell’s response to Siegel’s blog about breaking quantum entanglement and slowing down quantum communications — Orzell highlights some of the problems with Siegel’s statement about how quantum entanglement can be broken via two opposing states. The problem with Siegel’s statement is not with the breaking of entanglement slows down quantum communications; Orzell’s concern is with the details that Siegel describes in how it happens is the problem according to Orzell. Orzell highlights that the 2 state’s that Siegel shares as details to why and how the breakage occurs are not close enough by definition to make the argument valid because one is only a measurement while the other is the actual changing of state followed by a measurement.
Quantum entanglement is one of the weirdest and coolest phenomena in physics, but it’s absolutely not a method for sending messages faster than light, for subtle and complicated reasons.

IBM’s Quantum Experience brings quantum computing to the masses via the cloud
Posted by Karen Hurst in categories: computing, information science, quantum physics
Hmmm; my verdict is out for now because I haven’t seen anything showing me that IBM is a real player in this space.
IBM is bringing quantum computing to a device near you by delivering its IBM Quantum Experience through the IBM Cloud. The platform is part of IBM’s Research Frontiers Institute and could be a data scientist’s newest tool and a data junkie’s dream come true.
The platform is available on any desktop or mobile device. The tech allows users to “run algorithms and experiments on IBM’s quantum processor, work with the individual quantum bits (qubits), and explore tutorials and simulations around what might be possible with quantum computing,” the press release noted.

IBM Quantum Computing To Accelerate Cloud Innovation
Posted by Karen Hurst in categories: quantum physics, supercomputing
Hmmm; my verdict is out for now.
IBM Quantum Computing Scientist Jay Gambetta uses a tablet to interact with the IBM Quantum Experience, the world’s first quantum computing platform delivered via the IBM Cloud at IBM’s T. J. Watson Research Center in Yorktown, NY.
On Wednesday, May 4, for the first time ever, IBM is making quantum computing available via the cloud to anyone interested in hands-on access to an IBM quantum processor, making it easier for researchers and the scientific community to accelerate innovations, and help discover new applications for this technology. This is the beginning of the quantum age of computing and the latest advance from IBM towards building a universal quantum computer. A universal quantum computer, once built, will represent one of the greatest milestones in the history of information technology and has the potential to solve certain problems we couldn’t solve, and will never be able to solve, with today’s classical computers.

Quantum logical operations realized with single photons
Posted by Karen Hurst in categories: computing, particle physics, quantum physics
More insights around the logical quantum gate for photons discovered by Max Planck Institute of Quantum Optics (MPQ). Being able to leverage this gate enables Qubits in transmission and processing can be more controlled and manipulated through this discovery, and places us closer to a stable Quantum Computing environment.
MPQ scientists take an important step towards a logical quantum gate for photons.
Scientists from all over the world are working on concepts for future quantum computers and their experimental realization. Commonly, a typical quantum computer is considered to be based on a network of quantum particles that serve for storing, encoding and processing quantum information. In analogy to the case of a classical computer a quantum logic gate that assigns output signals to input signals in a deterministic way would be an essential building block. A team around Dr. Stephan Dürr from the Quantum Dynamics Division of Prof. Gerhard Rempe at the Max Planck Institute of Quantum Optics has now demonstrated in an experiment how an important gate operation — the exchange of the binary bit values 0 and 1 — can be realized with single photons. A first light pulse containing one photon only is stored as an excitation in an ultracold cloud of about 100,000 rubidium atoms.

US intelligence awards multimillion dollar grant to Sydney University quantum science lab
Posted by Karen Hurst in categories: neuroscience, quantum physics, science, security
All I can say is WOW!!!! US Security Intelligence awards contract to University of Sydney who is also partnering with China. Also, this should send a huge message to the university in the US that Sydney is kicking it.
The US office of the director of national intelligence has awarded a mutlimillion dollar research grant to an international consortium that includes a quantum science laboratory at the University of Sydney.

Australia opens quantum computing lab in Sydney
Posted by Karen Hurst in categories: quantum physics, supercomputing
I am totally jealous right now!
Australia opened a new quantum computing lab at the University of New South Wales (UNSW).
This follows the government’s $26-million investment in the Centre of Excellence for Quantum Computation & Communication Technology (CQC2T) as part of the National Innovation and Science Agenda. The government’s investment is supported by $10 million each from Telstra and the Commonwealth Bank of Australia (CBA).

An experiment seeks to make quantum physics visible to the naked eye
Posted by Shailesh Prasad in categories: particle physics, quantum physics
Predictions from quantum physics have been confirmed by countless experiments, but no one has yet detected the quantum physical effect of entanglement directly with the naked eye. This should now be possible thanks to an experiment proposed by a team around a theoretical physicist at the University of Basel. The experiment might pave the way for new applications in quantum physics.
Quantum physics is more than 100 years old, but even today is still sometimes met with wonderment. This applies, for example, to entanglement, a quantum physical phenomenon that can be observed between atoms or photons (light particles): when two of these particles are entangled, the physical state of the two particles can no longer be described independently, only the total system that both particles form together.
Despite this peculiarity, entangled photons are part of the real world, as has been proven in many experiments. And yet no one has observed entangled photons directly. This is because only single or a handful of entangled photons can be produced with the available technology, and this number is too low for the human eye to perceive these photons as light.
