Breakthrough Quantum Hardware to be Made in USA

Maybell’s Icebox Dilution Refrigerator condenses a room-sized cryogenic setup into a system slightly larger than a kitchen fridge, cooling quantum devices to just a few thousandths of a degree above absolute zero.Maybell Quantum unveiled the Icebox, a cryogenic platform to power the next generation of quantum computers. Maybell's condenses a room-sized cryogenic setup into a system slightly larger than a kitchen fridge, cooling quantum devices to just a few thousandths of a degree above absolute zero. Maybell's Icebox solves several pressing challenges for scaling quantum. Quantum computing is a reinvention of computing. It will perform calculations in seconds that would require billions of years for today's most powerful supercomputers, with profound implications for everything from logistics and agriculture to medicine and climate change. But achieving reliable quantum computation requires qubits – quantum computers' fundamental building block – to be in a state where they can be finely manipulated and communicated with through minute signals. Maybell's approach to these challenges has attracted contracts from DARPA, NSIC/DIU and leading research universities, and is now available to the quantum computing industry.

JILA Atomic Clocks Measure Einstein’s General Relativity at Millimeter Scale

JILA researchers measured time dilation, or how an atomic clock's ticking rate varied by elevation, within this tiny cloud of strontium atoms. Credit: R. Jacobson/NISTPhysicists from JILA (formerly known as the Joint Institute for Laboratory Astrophysics, a physical science research institute at the University of Colorado Boulder campus and jointly operated by the National Institute of Standards and Technology [NIST] and the University of Colorado Boulder) have measured Albert Einstein’s theory of general relativity (or more specifically, the effect called time dilation) at the smallest scale ever, showing that two tiny atomic clocks separated by just a millimeter, or the width of a sharp pencil tip, tick at different rates.

Ardent Concepts, Inc. Releases High-Density Ganged Coaxial Attenuators to Support Scale-up of Cryogenic and Quantum Computing Applications

ArdentAmphenol Ardent Concepts, a leading supplier of ganged coaxial connectors for use in cryogenic environments, has released high-density ganged coaxial attenuators for in-line use with the TR Multicoax™ series to support the many unique challenges of scaling up quantum computing applications for practical use. Density, substantial environmental changes, and an increasing need for more high-speed lanes are causing quantum computer designers to rethink traditional routing methods. By utilizing industry-leading materials like oxygen-free high thermal conductivity, copper and NiCr on thermally conductive crystalline quartz dielectric, engineers will be able to drastically decrease real estate required by individual attenuators with minimal change in attenuation to temperature delta down to 3 milliKelvin.

Misconceptions in Cryogenic Heat Management

Liquid nitrogen cold shock of a flight tank simulator. Image: James FesmireMisconceptions abound in the world, and some are more important to address than others. In the area of cryogenic heat management there are misconceptions that usually have no ill effect but sometimes can become big stumbling blocks. These center around the confusion of temperature and heat (with the word “thermal” thrown in here and there). Temperature is an indicator of what the heat is doing, but it is not heat.

DESI Creates Largest 3D Map of the Cosmos

DESI’s three-dimensional “CT scan” of the Universe. The earth is in the lower left, looking out over 5 billion light years in the direction of the constellation Virgo. As the video progresses, the perspective sweeps toward the constellation Bootes. Each colored point represents a galaxy, which in turn is composed of hundreds of billions of stars. Gravity has pulled the galaxies into a “cosmic web” of dense clusters, filaments and voids. Image: D. Schlegel/Berkeley Lab using data from DESIThe Dark Energy Spectroscopic Instrument (DESI) has capped off the first seven months of its survey run by smashing through all previous records for three-dimensional galaxy surveys, creating the largest and most detailed map of the universe ever. Yet it’s only about 10% of the way through its five-year mission. Once completed, that phenomenally detailed 3D map will yield a better understanding of dark energy, and thereby give physicists and astronomers a better understanding of the past – and future – of the universe. Meanwhile, the impressive technical performance and literally cosmic achievements of the survey thus far are helping scientists reveal the secrets of the most powerful sources of light in the universe. DESI is an international science collaboration managed by the Department of Energy’s (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) with primary funding for construction and operations from DOE’s Office of Science.

Credit: NASACooling things down in space is trickier than it might sound, but that is exactly the process the James Webb telescope is going through right now. Getting down to cryogenic temperature is imperative for its infrared imaging systems to work correctly. While the telescope has already started, it will be another few weeks before the process is complete and it's ready to capture its first groundbreaking infrared images of the universe. That might seem like an exceptionally long time to cool something down; however, it's par for the course in space.

Custom Manufacturing of MLI Blankets: Top Three Outsourcing Considerations

When OEMs and contract manufacturing organizations (CMOs) partner on custom MLI blankets, the OEM typically supplies a 3D model of the product requiring insulation. The CMO uses this model to develop a 3D blanket design, then transforms that 3D design into a 2D pattern, cuts insulation material layers into pattern pieces, and sews the pieces into a 3D blanket to fit over the product. Image courtesy of Web Industries. Image: Web Industries, Inc.Multilayer insulation (MLI) blankets must conform to exacting specifications to insulate high value products, from MRI machine components in the medical sector to satellites and other spacecraft.  Partnering with an MLI blanket contract manufacturer relieves the OEM of many processing steps and can expedite production cycle time for these highly customized products. In this article, we will discuss three of the most important considerations to keep in mind when deciding whether to outsource custom MLI blanket manufacturing and what capabilities to seek in a contract manufacturing organization (CMO).

Scientists Produce First In-Vitro Lion Embryos

Freshly isolated African lion oocytes. Credit: Jennifer Zahmel/Leibniz-IZWA team of scientists have succeeded in producing the very first African lion in-vitro embryos after the vitrification of immature oocytes. For this specific method of cryopreservation, the scientists, who hail from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) in Germany, Givskud Zoo–Zootopia in Denmark, and the University of Milan, collected oocytes directly after an animal was castrated or deceased and immediately froze them at -196°C in liquid nitrogen. This technique allows the storage of oocytes of valuable animals for an unlimited time so they can be used to produce offspring with the help of assisted reproduction techniques. The aim is to further improve and apply these methods to save highly endangered species, such as the Asiatic lion, from extinction. The current research on African lions as a model species is an important step in this direction. The results are reported in the scientific journal, Cryobiology.

#BlackInQuantum

Illustration by Sandbox Studio, Chicago with Ana KovaBlack scientists have played important roles in the history of quantum physics. In this growing area of specialization, there’s an opportunity to continue that legacy. The sixth person to earn a doctoral degree in physics from an American institution was African American scientist Edward Alexander Bouchet; it was 1876, just 11 years after the US had adopted a constitutional amendment that outlawed slavery. Never again have African Americans made up such a large percentage of US physicists. In fact, it would take another 42 years before a second African American man earned a physics PhD in the United States.
