ABS Signs Teleport Deal with Telemedia

Posted by in categories: biotech/medical, computing, engineering, quantum physics

ABS is partnering with Telemedia, a broadcasting and teleport service provider in South Africa, to improve its service offerings to customers in the Middle East and Africa region (MEA). ABS announced Monday that the company will gain access to a full suite of telecom services provided by Telemedia at its Johannesburg teleport. Telemedia will provide teleport fiber connectivity, data center hosting, and satellite uplink capabilities.

Telemedia said the partnership enables the company to further expand its broadcast and satellite connectivity services in the MEA.

“Our collaboration with Telemedia reinforces and strengthens our presence in the MEA and provides an extension to our global connectivity network,” Ron Busch, ABS’ EVP Engineering and Operations said. “[Telemedia’s] infrastructure offering with a solid track record, excellent customer support and can-do attitude during the COVID-19 pandemic shows its commitment to excellent customer service.”

A Powerful Ion Microscope Developed to Study Quantum Gases

Posted by in categories: particle physics, quantum physics

University of Stuttgart researchers developed a particle-based imaging approach that enables the spatially and temporally resolved investigation of vastly different systems such as ground-state samples, Rydberg ensembles, or cold ions immersed in quantum gases.

The microscope features an excellent time resolution allowing for both the study of dynamic processes and 3D imaging. In contrast to most quantum gas microscopes, this imaging scheme offers an enormous depth of field and is, therefore, not restricted to two-dimensional systems.

The researchers plan to use their new and powerful tool to extend our studies of cold ion-atom hybrid systems and intend to push the collision energies in these systems to the ultracold regime. Using Rydberg molecules to initialize ion-atom collisions, they envision the imaging of individual scattering events taking place in the quantum regime.

Hyperchaos Phenomenon Used to Model Complex Quantum Systems at a Fraction of the Computing Power

Posted by in categories: quantum physics, supercomputing

Physicists have discovered a potentially game-changing feature of quantum bit behavior that would allow scientists to simulate complex quantum systems without the need for enormous computing power.

For some time, the development of the next generation of quantum computers has limited by the processing speed of conventional CPUs.

Even the world’s fastest supercomputers have not been powerful enough, and existing quantum computers are still too small, to be able to model moderate-sized quantum structures, such as quantum processors.

Full stack ahead: Pioneering quantum hardware allows for controlling up to thousands of qubits at cryogenic temperatures

Posted by in categories: chemistry, computing, encryption, quantum physics, space

Quantum computing offers the promise of solutions to previously unsolvable problems, but in order to deliver on this promise, it will be necessary to preserve and manipulate information that is contained in the most delicate of resources: highly entangled quantum states. One thing that makes this so challenging is that quantum devices must be ensconced in an extreme environment in order to preserve quantum information, but signals must be sent to each qubit in order to manipulate this information—requiring, in essence, an information superhighway into this extreme environment. Both of these problems must, moreover, be solved at a scale far beyond that of present-day quantum device technology.

Microsoft’s David Reilly, leading a team of Microsoft and University of Sydney researchers, has developed a novel approach to the latter problem. Rather than employing a rack of room-temperature electronics to generate voltage pulses to control qubits in a special-purpose refrigerator whose base temperature is 20 times colder than interstellar space, they invented a control chip, dubbed Gooseberry, that sits next to the quantum device and operates in the extreme conditions prevalent at the base of the fridge. They’ve also developed a general-purpose cryo-compute core that operates at the slightly warmer temperatures comparable to that of interstellar space, which can be achieved by immersion in liquid Helium. This core performs the classical computations needed to determine the instructions that are sent to Gooseberry which, in turn, feeds voltage pulses to the qubits. These novel classical computing technologies solve the I/O nightmares associated with controlling thousands of qubits.

Quantum computing could impact chemistry, cryptography, and many more fields in game-changing ways. The building blocks of quantum computers are not just zeroes and ones but superpositions of zeroes and ones. These foundational units of quantum computation are known as qubits (short for quantum bits). Combining qubits into complex devices and manipulating them can open the door to solutions that would take lifetimes for even the most powerful classical computers.

Consciousness: Evolution of the Mind, Documentary (2021), Official Trailer Released

Posted by in categories: biotech/medical, chemistry, education, evolution, neuroscience, quantum physics

If we are to reason for the non-dual picture of the world then quantum physics is directly linked to consciousness. The human brain is a physical organ that transmits and interprets electrochemical signals. Its biochemistry is certainly governed by quantum physical laws, and consciousness — which is clearly related to the functioning of the brain — must therefore be related to the quantum physical processes going on within the brain and in the cosmos at large. Research has shown that consciousness is non-local, a scientific way of alluding to a connection within a higher dimensional order. Matter has also been shown to be non-local, which hints that matter might be an expression of consciousness. Quantum physics tells us the energy of every speck of mass, or a packet of information, is a relative peak in an ocean of energy, which is oftentimes referred to as the ‘Unified Field’ — the quantum layer of pure potentiality — the code layer beneath all dimensions where time and space are information.
