Deconstructing Schrödinger’s Cat – Solving the Paradox

Posted by in categories: information science, particle physics, quantum physics

The French theoretical physicist Franck Laloë presents a modification of Schrödinger’s famous equation that ensures that all measured states are unique, helping to solve the problem that is neatly encompassed in the Schördinger’s cat paradox.

The paradox of Schrödinger’s cat – the feline that is, famously, both alive and dead until its box is opened – is the most widely known example of a recurrent problem in quantum mechanics: its dynamics seems to predict that macroscopic objects (like cats) can, sometimes, exist simultaneously in more than one completely distinct state. Many physicists have tried to solve this paradox over the years, but no approach has been universally accepted. Now, however, theoretical physicist Franck Laloë from Laboratoire Kastler Brossel (ENS-Université PSL) in Paris has proposed a new interpretation that could explain many features of the paradox. He sets out a model of this possible theory in a new paper in EPJ D.

One approach to solving this problem involves adding a small, random extra term to the Schrödinger equation, which allows the quantum state vector to ‘collapse’, ensuring that – as is observed in the macroscopic universe – the outcome of each measurement is unique. Laloë’s theory combines this interpretation with another from de Broglie and Bohm and relates the origins of the quantum collapse to the universal gravitational field. This approach can be applied equally to all objects, quantum and macroscopic: that is, to cats as much as to atoms.

The realization of a single-quantum-dot heat valve

Posted by in categories: computing, nanotechnology, quantum physics

While many research teams worldwide are trying to develop highly performing quantum computers, some are working on tools to control the flow of heat inside of them. Just like conventional computers, in fact, quantum computers can heat up significantly as they are operating, which can ultimately damage both the devices and their surroundings.

A team of researchers at University Grenoble Alpes in France and Centre of Excellence—Quantum Technology in Finland has recently developed a single-quantum-dot heat valve, a that can help to control the flow of heat in single-quantum-dot junctions. This heat valve, presented in a paper published in Physical Review Letters, could help to prevent quantum computers from overheating.

“With the miniaturization of electronic components handling of excess heat at nanoscales has become an increasingly important issue to be addressed,” Nicola Lo Gullo, one of the researchers who carried out the study, told Phys.org. “This is especially true when one wants to preserve the quantum nature of a device; the increase in temperature does typically result in the degradation of the quantum properties. The recent realization of a photonic heat-valve by another research group ultimately inspired us to create a heat valve based on a solid-state quantum dot.”

The new ‘gold rush’ for green lithium

Posted by in categories: climatology, computing, mobile phones, solar power, sustainability

All the clean technologies that we need to combat climate change – whether that’s wind turbines, solar panels or batteries, they’re all really, really mineral intensive.


Cornwall, 1864. A hot spring is discovered nearly 450m (1485ft) below ground in the Wheal Clifford, a copper mine just outside the mining town of Redruth. Glass bottles are immersed to their necks in its bubbling waters, carefully sealed and sent off for testing. The result is the discovery of so great a quantity of lithium – eight or 10 times as much per gallon as had been found in any hot spring previously analysed – that scientists suspect “it may prove of great commercial value”.

But 19th-Century England had little need for the element, and this 50C (122F) lithium-rich water continued steaming away in the dark for more than 150 years.

Verizon, UPS, and Skyward announce connected drone delivery at CES 2021

Posted by in categories: business, drones, internet

PORTLAND, Ore. — Skyward, A Verizon company, and UPS Flight Forward today announced collaborative efforts to deliver retail products with drones connected to Verizon 4G LTE, as well as 5G testing and integration for delivery. The companies aim to deliver retail products via connected drones at The Villages in Florida.

“We will need the ability to manage and support multiple drones, flying simultaneously, dispatched from a centralized location, operating in a secure and safe environment. To do this at scale, alongside Verizon and Skyward, we’ll need the power of 5G,” said Carol B. Tomé, CEO of UPS.

“We’re just beginning to see how the power of 5G Ultra Wideband will transform the way businesses operate,” said Rima Qureshi, Chief Strategy Officer at Verizon. “By partnering with UPS and other innovative companies, we can learn from each other’s expertise and collaborate to create solutions that help move the world forward.”
