Unlike classical encryption, which relies on mathematical algorithms, quantum encryption assures security based on physical principles. Detection of espionage or interference is guaranteed by unavoidable alteration of the quantum states involved.
Quantum computing is one of those “just around the corner” technologies that have the scientific community split. Tech outfits such as Google and IBM have gone full throttle with both research and development and marketing as if they’re already here, while many independent researchers have claimed quantum computers will never work.
Most people working in the field, however, believe that quantum computers will be able to solve problems that classical computers can’t solve within the next 10 years.
This is according to a recent survey of 927 people with associations to the field of quantum computing (researchers, executives, press, enthusiasts, etc.) conducted by QuEra. Of those surveyed, 74.9% “expect quantum to be a superior alternative to classical computing for certain workloads” within the next 10 years.
This LHP (loop heat pipe) is unprecedented in transporting such a large amount of heat without electricity.
In a groundbreaking development, scientists at Nagoya University in Japan have created the world’s most powerful loop heat pipe (LHP), capable of transporting an astounding 10 kilowatts of heat without using any electricity. This innovation promises to revolutionize energy efficiency across multiple industries, from electric vehicles to data centers.
Understanding Loop Heat Pipes
Before delving into the significance of this breakthrough, let’s explore what loop heat pipes are and how they work. LHPs are passive heat transfer devices that use the principles of phase change and capillary action to move heat from one place to another. They consist of an evaporator, a condenser, and connecting pipes filled with a working fluid.

Data centers are facilities that house the computing hardware used to process and store data. While some businesses maintain their own data centers on site, many others rely on ones owned and operated by someone else.
As our digital world continues to grow, demand for data centers — and clean electricity to operate them — is also increasing. To find out how we’ll be able to keep up, let’s look at the history of data centers, the challenges facing them, and ideas for overcoming those issues — on land, at sea, and in space.
Researchers at the University of Chicago Pritzker School of Molecular Engineering (PME) have made unexpected progress toward developing a new optical memory that can quickly and energy-efficiently store and access computational data. While studying a complex material composed of manganese, bismuth and tellurium (MnBi2Te4), the researchers realized that the material’s magnetic properties changed quickly and easily in response to light. This means that a laser could be used to encode information within the magnetic states of MnBi2Te4.
Light is an excellent carrier of information used not only for classical communication technologies but also increasingly for quantum applications such as quantum networking and computing. However, processing light signals is far more complex, compared to working with common electronic signals.
PEARC24 launched its first Workshop on Broadly Accessible Quantum Computing (QC) as the full conference began, July 22, in Providence, RI. Led by NCSA’s Bruno Abreu and QuEra’s Tomasso Macri, 30+ participants included quantum chemists, system administrators, software developers, research computing facilitators, students and others looking to better understand the current status and the prospects of QC and its applications.
