Quobly Demonstrates Key Quantum Operations on 300 mm Silicon Chip

Quobly, a French quantum computing company developing industrially scalable quantum computers based on silicon spin qubits, today announces new results showing qubit readout, single-qubit gates and two-qubit gates on a single quantum chip fabricated on its proprietary QSOI® technology. The results were obtained on QSOI® devices fabricated in STMicroelectronics’ commercial...

NASA Selects Far-Infrared Telescope as First in New Mission Class

NASA recently announced a mission to explore the history and evolution of the universe, PRIMA (PRobe far-Infrared Mission for Astrophysics), is advancing to the next phase of development. This space telescope is the first in a new class of NASA astrophysics missions, called Probe Explorers, within the agency’s longstanding Explorers...

Emergence Quantum and AirTrunk Partner on Cryogenic Data Centers

Emergence Quantum recently announced a partnership with hyperscale data center specialist AirTrunk to bring cryogenic cooling and quantum computing to next-generation data centers. Cryo-cooling can significantly improve the speed and energy-efficiency of today’s silicon computer chips, enabling faster computation with less power. The same cryo-technology is also foundational to many...

Researchers Turned “Empty Space” Into a Tool for Superconductivity

Empty space is not truly empty. Even a vacuum contains restless quantum fluctuations, and researchers have now shown for the first time that these normally subtle effects can be engineered to strengthen superconductivity. The work, led by Changgan Zeng and Guanghui Cheng of the University of Science and Technology of...

India Develops Indigenous Helium Cryocooler for Quantum and Space Research

India has achieved another milestone in deep-tech research by joining the highly exclusive group of nations possessing closed-loop cryogenic refrigeration technology. The Raja Ramanna Centre for Advanced Technology has successfully developed a Gifford-McMahon cryocooler capable of reaching minus 243 degrees Celsius, equivalent to 30 Kelvin, along with an indigenous helium...

Intel CEO Sees Quantum Computing Working Alongside CPUs and GPUs

Intel Chief Executive Lip-Bu Tan said quantum computers are likely to work alongside conventional processors rather than replace them, as the industry searches for commercially useful applications. “In my view, GPUs, CPUs and quantum computing are all forms of computing, so they will run together in certain application areas, and...

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

Scottish Researchers Develop 100kW Superconducting Motor for Aircraft

Scottish researchers have demonstrated a 100kW superconducting motor that could pave the way for future electric aircraft. The prototype, created in the Applied Superconductivity Laboratory (ASL) of the University of Strathclyde in Glasgow, is one of the first attempts in the world to develop a fully superconducting axial-flux motor for...

You are encouraged to read Cryo Central’s History...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
