Quantum errors made more tolerable

Posted by in categories: computing, quantum physics

ETH physicists have modified one of the major schemes for quantum error correction and put it into practice, demonstrating that they can substantially prolong the lifetime of quantum states—a crucial ingredient for future large-scale quantum computers.

In modern computing devices, literally billions of transistors work restlessly in almost perfect harmony. The keys to producing near-perfect computation from devices made from imperfect components are the use of digitisation and error correction, with the latter encompassing procedures to detect and rectify inaccuracies as they occur. The challenge of preventing errors from accumulating is one that future quantum computers have to face as well—in fact it forms the main barrier to realizing useful computations. Alas, the tools that have been perfected for classical computers cannot be applied directly to quantum computers, which play by another set of rules, those of quantum mechanics. Ingenious solutions for quantum error correction have been proposed over the past couple of decades, and recently there has been encouraging progress towards implementing such methods in state-of-the-art quantum computers. Writing in Nature Physics, the group of Prof.

First gene therapy for Tay-Sachs disease successfully given to two children

Posted by in categories: biotech/medical, neuroscience

About 1 in 300 people in the general population carry the Tay-Sachs disease gene. Ray Kachatorian/Stone via Getty ImagesTwo babies have received the first-ever gene therapy for Tay-Sachs disease after over 14 years of development. Tay-Sachs is a severe neurological disease caused by a deficiency in an enzyme called HexA. This enzyme breaks down a fatlike substance that normally exists in very small, harmless amounts in the brain. Without HexA, however, this fatlike substance can accumulate to toxic levels that damage and kill neurons.

VR’s Biggest Ad Yet Pushed ‘Meta Quest’ to a National Audience During the Super Bowl

It’s hard to find a single event with a bigger audience than the Super Bowl, which has made it one of the hottest pieces of advertising real estate anywhere. Meta went big this year with a 60 second ad spot that served to both promote VR to a national audience and solidify its rebranding from Oculus Quest 2 to Meta Quest 2.

If you were watching the Rams and Bengals duke it out during Super Bowl 56 on Sunday, you will also have been introduced to ‘Questy’s’ in an ad during the first quarter. The 60 second spot, which centered around a personified animatronic band that once played at a restaurant called Questy’s, was likely the single most expensive VR-related ad ever shown on TV to date.

Monitoring the high seas at high altitude

Posted by in categories: government, space

Previously, aircraft ✈️ had to fly at 1,500 to 5,000 feet for airborne radars to detect illegal activity in our seas 🌊. With SeaVue Multi-Role, pilots can fly as… See more.


In some parts of the world, the sea is lawless, fraught with piracy, smuggling and illegal fishing.

To help navies and coastal authorities combat illegal activity, Raytheon Intelligence & Space has developed the SeaVue family of airborne radars, which detect small maritime targets such as illegal fishing vessels, go-fast boats and stateless ships—ships not registered to a country or government, on the high seas. RI&S engineers have added a new, upgraded radar to the family called SeaVue Multi-Role.

Scientists discover new electrolyte for solid-state lithium-ion batteries

Posted by in category: energy

In the quest for the perfect battery, scientists have two primary goals: create a device that can store a great deal of energy and do it safely. Many batteries contain liquid electrolytes, which are potentially flammable.

As a result, solid-state lithium-ion batteries, which consist of entirely solid components, have become increasingly attractive to scientists because they offer an enticing combination of higher safety and increased energy density—which is how much energy the battery can store for a given volume.

Researchers from the University of Waterloo, Canada, who are members of the Joint Center for Energy Storage Research (JCESR), headquartered at the U.S. Department of Energy’s (DOE) Argonne National Laboratory, have discovered a new solid electrolyte that offers several important advantages.

Shape-shifting material morphs robot from driving to flying

Posted by in categories: drones, robotics/AI

A new shape-shifting material out of Virginia Tech can be used to give robots the power to transform smoothly between different shapes — like going from a drivable robot to a flying drone.

The challenge: Most of today’s robots are really good at one function — drones are designed to fly, but they can’t swim, and wheeled bots can drive, but they can’t fly.

The few exceptions typically use complex systems of motors, gears, and hinges to reconfigure themselves into different shapes suited for different tasks, but every extra part is a new potential point of failure.
