Ions trapped nanoscale optical cavities could be used to distribute entangled quantum particles over large distances. That is the conclusion of Jonathan Kindem and colleagues at Caltech in the US, who showed that a trapped ion of ytterbium can remain entangled with a photon for long periods of time. Furthermore, the team showed that the ion’s quantum state can be read out when manipulated by laser and microwave pulses. Their achievement could lay the foundations for a future quantum internet.

Quantum computers are becoming a reality as research labs and companies roll out nascent devices. An important next step in this quantum revolution is creating a “quantum internet” across which quantum information can be shared. The delicate nature of quantum information, however, means that it is very difficult to connect quantum computers over long distances.

Most quantum computers encode quantum bits (qubits) of information into the quantum states of matter – trapped atoms or superconducting circuits, for example. However, the best way to transmit quantum information over long distances is to encode it into a photon of light. An important challenge is how to transfer quantum information from stationary matter-based qubits to photon-based “flying” qubits and then back again.

Health hysteria has plagued the communications industry for decades despite the lack of evidence. 5G is no different.

Around a year ago…

Pretty cool.

A team of University of Florida engineers developed a cheap and easily sourced ventilator made with PVC, sprinkler valves, and Arduino. The design can be made for around $125 and could help with the demand for ventilators in the COVID-19 pandemic.

A ventilator envisioned by a University of Florida engineer and built with do-it-yourself parts gained first-step FDA authorization this week, offering hope that it could be in use within weeks at hospitals around the world where COVID-19 patients have overwhelmed supplies of traditional medical equipment.

The ventilator, composed of parts readily available for less than $250, can be assembled in less than an hour. UF has made plans and software available free over the internet.

Researchers at the University of North Carolina at Chapel Hill made a one-way street for electrons that may unlock the ability for devices to process ultra-high-speed wireless data and simultaneously harvest energy for power. The researchers did this by shaping silicon on a microscopic scale to create a funnel, or “ratchet,” for electrons.

This method overcomes the speed limitations of prior technologies by removing interfaces that tend to slow down devices.” This work is exciting because it could enable a future where things like low-power smartwatches are wirelessly charged from the data they already receive without ever needing to a leave a person’s wrist,” said James Custer Jr., a doctoral student in UNC-Chapel Hill’s College of Arts & Sciences.

The findings were published April 10 in the journal Science. Custer is lead author. He worked with collaborators at Duke and Vanderbilt universities.

Google Chrome has dominated the internet browser market for the last decade with a staggering near-60% market share and users stretching into the billions.

Rivals to Google Chrome, including Apple’s Safari, Microsoft’s Edge (formerly known as Internet Explorer), and Mozilla’s Firefox have largely failed to convince users to switch—but browser choices are becoming more complex.

Users’ desire for greater security, better privacy, and an ill-defined need to “take back control” from the likes of Google and Microsoft has opened the door for alternatives—including blockchain-based privacy browser Brave, whose chief executive thinks Google “is going to be taken apart over coming years.”

A conspiracy theory linking 5G wireless networks to the Covid-19 pandemic is spreading. The theory is false — and psychologists explain why it is still so popular.

China has officially begun the research and development of 6G technology.

The news came less than a week after the country rolled out its superfast 5G network.

The country’s Technology Bureau has formally set up a team of experts to work on the next-generation mobile internet connection, state media said today.
