Efforts to invent more practical superconductors and better batteries could be the first areas of business to get a quantum speed boost.

Scientists found out that the ‘light barrier’ may be broken. This leads us closer to creating light-based computers and achieve computer speeds a million times faster than its speed today.

Using extremely short pulses of teraHertz (THz) radiation instead of electrical currents could lead to future computers that run ten to 100,000 times faster than today’s state-of-the-art electronics, according to an international team of researchers, writing in the journal Nature Photonics.

In a conventional computer, electrons moving through a semiconductor occasionally run into other electrons, releasing energy in the form of heat and slowing them down. With the proposed “lightwave electronics” approach, electrons could be guided by ultrafast THz pulses (the part of the electromagnetic spectrum between microwaves and infrared light). That means the travel time can be so short that the electrons would be statistically unlikely to hit anything, according to senior author Rupert Huber, a professor of physics at the University of Regensburg who led the experiment.

Tech big shots are charging into neuroscience, but do they even have a clue?

Launching small satellites with big storage capacities using the highest levels of security. Sensitive information is securely stored off-planet.

Researchers at ETH Zurich and IBM Research Zurich have built a tiny redox flow battery. This means that future computer chip stacks — in which individual chips are stacked like pancakes to save space and energy — could be supplied with electrical power and cooled at the same time by such integrated flow batteries (Energy & Environmental Science, “3D-printed fluidic networks for high-power-density heat-managing miniaturized redox flow batteries”).

In a flow battery, an electrochemical reaction is used to produce electricity out of two liquid electrolytes, which are pumped to the battery cell from outside via a closed electrolyte loop.

You can’t save data on a quantum computer. So a commercial one will need to use vintage tech—ultra dense hard drives, maybe made of DNA or single atoms.

Yorktown Heights, N.Y. — 06 Mar 2017: IBM (NYSE: IBM) announced today an industry-first initiative to build commercially available universal quantum computing systems. “IBM Q” quantum systems and services will be delivered via the IBM Cloud platform. While technologies that currently run on classical computers, such as Watson, can help find patterns and insights buried in vast amounts of existing data, quantum computers will deliver solutions to important problems where patterns cannot be seen because the data doesn’t exist and the possibilities that you need to explore to get to the answer are too enormous to ever be processed by classical computers.

Watson Research Center in Yorktown, NY. On Monday, March 6, IBM announced that it will build commercially available universal quantum computing systems. IBM Q quantum systems and services will be delivered via the IBM Cloud platform and will be designed to tackle problems that are too complex and exponential in nature for classical computing systems to handle. One of the first and most promising applications for quantum computing will be in the area of chemistry and could lead to the discovery of new medicines and materials. IBM aims at constructing commercial IBM Q systems with ~50 qubits in the next few years to demonstrate capabilities beyond today’s classical systems, and plans to collaborate with key industry partners to develop applications that exploit the quantum speedup of the systems.

Scientists now know how to code information into DNA as though it were a hard drive — the problem is, it’s really expensive to do.
