Quantum Teleportation Achieved Over Internet For First Time

A quantum state of light has been successfully teleported through more than 30 kilometers (around 18 miles) of fiber optic cable amid a torrent of internet traffic – a feat of engineering once considered impossible.

The impressive demonstration by researchers in the US may not help you beam to work to beat the morning traffic, or download your favourite cat videos faster.

However, the ability to teleport quantum states through existing infrastructure represents a monumental step towards achieving a quantum-connected computing network, enhanced encryption, or powerful new methods of sensing.

Magic Particles: The Large Hadron Collider’s Quantum Computing Breakthrough

Physicists uncovered a fascinating link between the Large Hadron Collider and quantum computing. They found that top quarks produced at the LHC exhibit a property called “magic,” essential for quantum computation.

This discovery could revolutionize our understanding of quantum mechanics and its applications, bridging the gap between quantum theory and particle physics.

Texas Instruments gets $1.6B from feds

Texas Instruments has announced a tranche of federal CHIPS Act funding worth up to $1.6 billion, a show of support for a semiconductor manufacturing industry that’s becoming more entrenched in North Texas.

Texas Instruments also expects to receive somewhere between $6 billion and $8 billion in U.S. Treasury tax credits for manufacturing investments, and up to $10 million to boost workforce development.

All told, the money will assist in funding three new Texas Instruments plants: two based in Sherman and one in Lehi, Utah, creating 2,000 new jobs. Separately, Samsung will receive as much as $4.75 billion in CHIPS Act money, a figure Bloomberg notes was below what was originally envisaged.

Singapore’s AQSolotl Introduces CHRONOS-Q: A Quantum Controller for Use in Integrating Classical and Quantum Computers

In a pioneering move for quantum technology, Nanyang Technological University (NTU) and the National University of Singapore (NUS) have launched AQSolotl, a deep-tech startup presenting CHRONOS-Q —a state-of-the-art quantum controller designed to integrate classical computing systems with quantum computers. This innovation positions Singapore at the forefront of the global quantum ecosystem, with wide-ranging applications across industries.

CHRONOS-Q tackles the complexity of controlling quantum computers by acting as a translator between classical and quantum systems. It enables efficient control via standard computing devices, features an intuitive interface, and significantly reduces operational barriers, paving the way for broader adoption. Its modular, compact design ensures scalability and suitability for diverse environments, from research labs to mobile quantum setups.

With groundbreaking speed—determining qubit states in under 14 nanoseconds—and customizable firmware, CHRONOS-Q promises cost-effective, future-proof solutions for academia and industry. The startup’s founders, including Professor Rainer Dumke from NTU and CEO Patrick Bore, emphasize the transformative potential of accessible quantum computing for solving global challenges.

This Cryptographer Helps Quantum-Proof the Internet

Users of Google’s Chrome browser can rest easy knowing that their surfing is secure, thanks in part to cryptographer Joppe Bos. He’s coauthor of a quantum-secure encryption algorithm that was adopted as a standard by the U.S. National Institute of Standards and Technology (NIST) in August and is already being implemented in a wide range of technology products, including Chrome.

Rapid advances in quantum computing have stoked fears that future devices may be able to break the encryption used by most modern technology. These approaches to encryption typically rely on mathematical puzzles that are too complex for classical computers to crack. But quantum computers can exploit quantum phenomena like superposition and entanglement to compute these problems much faster, and a powerful enough machine should be able to break current encryption.

Spintronics memory innovation: A new perpendicular magnetized film

Long gone are the days where all our data could fit on a two-megabyte floppy disk. In today’s information-based society, the increasing volume of information being handled demands that we switch to memory options with the lowest power consumption and highest capacity possible.

Magnetoresistive Random Access Memory (MRAM) is part of the next generation of storage devices expected to meet these needs. Researchers at the Advanced Institute for Materials Research (WPI-AIMR) investigated a cobalt-manganese-iron alloy thin film that demonstrates a high perpendicular magnetic anisotropy (PMA)—key aspects for fabricating MRAM devices using spintronics.

The findings were published in Science and Technology of Advanced Materials on November 13, 2024.

Advancing unidirectional heat flow: The next era of quantum thermal diodes

Heat management at the nanoscale has long been a cornerstone of advanced technological applications, ranging from high-performance electronics to quantum computing. Addressing this critical challenge, we have been deeply intrigued by the emerging field of thermotronics, which focuses on manipulating heat flux in ways analogous to how electronics control electric energy. Among its most promising advancements are quantum thermal diodes, which enable directional heat control, and quantum thermal transistors, which regulate heat flow with precision.

Thermal diodes, much like their electrical counterparts, provide unidirectional heat transfer, allowing heat to flow in one direction while blocking it in the reverse. We find this capability revolutionary for heat management, as it has the potential to transform numerous fields.

For instance, thermal diodes can significantly improve the cooling of high-performance electronics, where is a major bottleneck. They could also enable more efficient energy harvesting by converting into usable energy, contributing to sustainability efforts.
