As superconducting qubit circuits become more complex, addressing a large array of qubits becomes a challenging engineering problem. Dense arrays of qubits benefit from, and may require, access via the third dimension to alleviate interconnect crowding. Through-silicon vias (TSVs) represent a promising approach to three-dimensional (3D) integration in superconducting qubit arrays—provided they are compact enough to support densely-packed qubit systems without compromising qubit performance or low-loss signal and control routing. In this work, we demonstrate the integration of superconducting, high-aspect ratio TSVs—10 μm wide by 20 μm long by 200 μm deep—with superconducting qubits. We utilize TSVs for baseband control and high-fidelity microwave readout of qubits using a two-chip, bump-bonded architecture. We also validate the fabrication of qubits directly upon the surface of a TSV-integrated chip. These key 3D-integration milestones pave the way for the control and readout of high-density superconducting qubit arrays using superconducting TSVs.

They can be made up of just two surfaces, bouncing the wave between them, but the more surfaces that are added, the more resonance is achieved. The ultimate is therefore to create a perfect sphere, creating surfaces in every direction within a three-dimensional object. At that point, the creation of a resonator moves from being a physics question to one of engineering, since even a stem holding the sphere can create distortion that reduces the impact of the resonator.

According to the Technion, the world’s first micro-resonator was demonstrated in the 1970s by Arthur Ashkin, winner of the 2018 Nobel Prize in Physics, who presented a floating resonator. Yet, despite the success of his innovation, the research direction was soon abandoned.

Now graduate student Jacob Kher-Alden, under the supervision of Prof. Tal Carmon, has built upon Ashkin’s work, creating a floating resonator which can exhibit resonant enhancement by ten million circulations of light, compared to about 300 circulations in Ashkin’s resonator.

BT and Toshiba have deployed an ‘unhackable’ quantum network that uses streams of photons to encrypt sensitive communications.

A trial of the network, which is the first of its kind in the UK, will see data transmitted between two engineering facilities in Bristol using encryption keys streamed as ‘encoded’ particles of light.

Technion researchers have developed accurate radiation sources that are expected to lead to breakthroughs in medical imaging and other areas. They have developed precise radiation sources that may replace the expensive and cumbersome facilities currently used for such tasks. The suggested apparatus produces controlled radiation with a narrow spectrum that can be tuned with high resolution, at a relatively low energy investment. The findings are likely to lead to breakthroughs in a variety of fields, including the analysis of chemicals and biological materials, medical imaging, X-ray equipment for security screening, and other uses of accurate X-ray sources.

Published in the journal Nature Photonics, the study was led by Professor Ido Kaminer and his master’s student Michael Shentcis as part of a collaboration with several research institutes at the Technion: the Andrew and Erna Viterbi Faculty of Electrical Engineering, the Solid State Institute, the Russell Berrie Nanotechnology Institute (RBNI), and the Helen Diller Center for Quantum Science, Matter and Engineering.

The researchers’ paper shows an experimental observation that provides the first proof-of-concept for theoretical models developed over the last decade in a series of constitutive articles. The first article on the subject also appeared in Nature Photonics. Written by Prof. Kaminer during his postdoc at MIT, under the supervision of Prof. Marin Soljacic and Prof. John Joannopoulos, that paper presented theoretically how two-dimensional materials can create X-rays. According to Prof. Kaminer, “that article marked the beginning of a journey towards sources based on the unique physics of two-dimensional materials and their various combinations—heterostructures. We have built on the theoretical breakthrough from that article to develop a series of follow-up articles, and now, we are excited to announce the first experimental observation on the creation of X-ray radiation from such materials, while precisely controlling the radiation parameters.”

Based on focused -induced processing (FEBID) techniques, the work could allow production of 2-D/3D complex nanostructures and functional nanodevices useful in quantum communications, sensing, and other applications. For oxygen-containing materials such as graphene oxide, etching can be done without introducing outside materials, using oxygen from the substrate.

“By timing and tuning the energy of the electron , we can activate interaction of the beam with oxygen in the graphene oxide to do etching, or interaction with hydrocarbons on the surface to create carbon deposition,” said Andrei Fedorov, professor and Rae S. and Frank H. Neely Chair in the George W. Woodruff School of Mechanical Engineering at the Georgia Institute of Technology. “With atomic-scale control, we can produce complicated patterns using direct write-remove processes. Quantum systems require precise control on an atomic scale, and this could enable a host of potential applications.”

Gryphon provides digital engineering, analytics, cyber and cloud solutions to U.S. security organizations. It was awarded a $14million DARPA task order to support the development and demonstration of an uranium-based Nuclear Thermal Propulsion (NTP) System.

The system is a part of the Demonstration Rocket for Agile Cislunar Operations (DRACO) program and will enable the U.S. military to operate spacecraft in cislunar space, Gryphon said. The cislunar space is the region outside the Earth’s atmosphere and just beyond the Moon’s orbit.

“A successfully demonstrated NTP system will provide a leap-ahead in space propulsion capability, allowing agile and rapid transit over vast distances as compared to present propulsion approaches,” said Gryphon’s Chief Engineer Dr. Tabitha Dodson.

“Gryphon is committed to providing high-end technical solutions to our nation’s most critical national security challenges,” said P.J. Braden, CEO of Gryphon. “We are proud to support DRACO and the development and demonstration of NTP, a significant technological advancement in efforts to achieve cislunar space awareness.”

Berlin, 30 September 2020. — The U.S. Defense Advanced Research Projects Agency (DARPA) tasked DC-based Gryphon Technologies to develop a nuclear thermal propulsion system, the firm announced yesterday.

Axiom Space Inc. is a Houston, Texas start-up, founded by Michael Suffredini who served as NASA’s International Space Station (ISS) Program Manager from 2005 to 2015. He was responsible for overseeing ISS transition from assembly to the initiation of commercial operations. Axiom is mostly staffed by NASA ex-employees, including former NASA Administrator Charles Bolden. – “The leadership team also includes world-class, specialized expertise in commercial utilization of microgravity, on-orbit operations, astronaut training, space financing, engineering, space system architecture/design/development, space medicine, marketing, and law,” the company states. Together, they are all working towards the commercialization of space.

Axiom aims to build a space station in low Earth orbit to continue operations once NASA retires the ISS program and moves beyond the orbiting laboratory to focus operations on the lunar surface. The company also offers spaceflights for regular civilians to experience microgravity and amazing views of Earth from ISS. “While making access to Low Earth Orbit global during the remainder of ISS’ lifetime, Axiom is constructing the future platform that will serve as humanity’s permanently growing home, scientific and industrial complex in Low Earth Orbit (LEO) – the cornerstone of human activity in space,” company states on its website.
