NTT develops quantum light source operating over optical fiber

NTT, in collaboration with the University of Tokyo, and RIKEN, unveiled an optical fiber-coupled quantum light source (squeezed light source) with the potential to serve as a building block for fault-tolerant, rack-sized, universal optical quantum computers.

Squeezed light is described as a non-classical light that has an even number of photons and squeezed quantum noise. It is used to generate quantum entanglement. NTT said squeezed light also plays an extremely important role in quantum error correction, since quantum error correction is made possible by utilizing the parity of the number of photons. 

In this project, the researchers sought a fiber-coupled squeezed light source with highly squeezed quantum noise and photon number parity that is maintained even in high-photon-number components (a squeezing level of over 65% is required to generate time-domain multiple quantum entanglement (two-dimensional clustered states) that can be used for large-scale quantum computation.) 

The researchers developed a new optical fiber-coupled quantum light source that operates at optical communication wavelengths. By combining it with optical fiber components, the researchers ached continuous-wave squeezed light with more than 75% squeezed quantum noise with more than 6 THz sideband frequency even in an optical fiber closed system for the first time. This means that the key device in optical quantum computers has been realized in a form that is compatible with optical fibers while maintaining the broadband nature of light. This will enable the development of an optical quantum computer in a stable and maintenance-free system using optical fibers and optical communication devices. 

NTT claims that by using a low-loss optical fiber as a propagation medium for flying optical qubits, large-scale quantum entangled states will be able to be generated freely and stably in combination with optical communication devices. Specifically, with only four squeezed light sources, two optical fibers of different lengths (optical delay lines), and five beam splitters, large-scale two-dimensional clustered states can be generated that are necessary for universal quantum computations.

NEC contributes packet core to DOCOMO's 5G SA services launch

NEC provided its packet core (5GC) and base stations (5G RUs, CU/DU) for the 5G standalone (SA)-based services that NTT DOCOMO launched commercially on December 13, 2021.

NEC's 5G Core for SA enables flexible operation for a variety of services thanks to its cloud-native architecture, featuring container and separation of Control and User Plane (CUPS). In addition, drawing on network slicing technology, NEC's 5GC for SA helps create customized networks on demand according to the different requirements for 5G services that include eMBB(enhanced Mobile Broadband), mMTC (massive Machine Type Communication), and URLLC (Ultra-Reliable and Low Latency Communications).

NEC confirmed that its 5G CU/DU, which was previously operating as non-standalone (NSA) on DOCOMO's commercial network, has been seamlessly migrated to 5G SA, simply by a software upgrade in conjunction with the aforementioned 5GC.

"5G SA enables the provision of networking solutions that can flexibly accommodate a wide variety of use cases," said Hiroshi Kobayashi, Senior Vice President NTT DOCOMO. "Through its 5G SA, NTT DOCOMO will contribute to the creation of new value and the resolution of social issues, and promote the further advancement of its 5G network to make the lives of its customers more convenient and prosperous."

"I am honored to have been able to contribute to the commercial launch of NTT DOCOMO's 5G SA services," said Atsuo Kawamura, Executive Vice President, NEC. "By providing high-quality and reliable 5GC and base station equipment, we will strongly support the expansion of DOCOMO's 5G services, as well as contribute to the further development of next-generation mobile infrastructure throughout global markets."

Google Cloud acquires Siemplify for security orchestration

Google Cloud has acquired Siemplify, a leading independent provider of security orchestration, automation and response (SOAR), in a deal reportedly valued at approximately US$500 million.  Siemplify was started in 2015 an is based in New York and Tel Aviv, Israel. Neither company confirmed the price.

The cloud-native Siemplify platform enables enterprise and Service Provider security teams to manage their operations from end to end, including responding to cyber threats with speed and precision. In 2020, the platform ingested hundreds of millions of alerts for customers and decreased caseload by as much as 80%.

The company says that part of its “secret sauce” is that the platform models data arriving from an organization’s collection of security tools into a graphical form, which expresses the meaningful components of each alert – for example, the source IP address in a phishing email. Machine learning can then easily “crawl” these graphs to isolate relationships and cluster together similar alerts into rich, aggregated cases.

We’re excited to join Google Cloud and build on the success we’ve had in the market helping companies address growing security threats,” said Amos Stern, CEO at Siemplify. “Together with Chronicle’s rich security analytics and threat intelligence, we can truly help security professionals transform the security operations center to defend against today’s threats."

AT&T added 270,000 fiber subscribers in Q4

AT&T added approximately 270,000 fiber subscribers in Q4 2021. Full-year 2021, fiber net adds totaled about 1.0 million, the fourth consecutive year in which the company has added 1 million or more fiber subscribers. AT&T ended the year with an additional 2.6 million fiber customer locations , compared to its prior expectation of about 2.5 million.   

At this week's Citi’s AppsEconomy Conference, AT&T provided the following additional data points for Q4:

  • For the fourth quarter of 2021, AT&T delivered total postpaid net adds of 1.3 million, including approximately 880,000 postpaid phones.
  • For the full-year 2021, postpaid phone net adds were 3.2 million, AT&T’s highest annual postpaid phone net adds in more than a decade as the company continues to benefit from strong network performance and its disciplined and consistent go-to-market strategy. 
  • AT&T ended the year with approximately 73.8 million total global HBO Max and HBO subscribers, ahead of management’s prior guidance that end-of-year subscribers would be at the high end of its 70 million to 73 million subscriber target.

STACK plans a new 216MW flagship Ashburn campus

In direct response to hyperscale client demands, STACK Infrastructure unveiled plans for a new 216MW campus in Ashburn, Virginia. 

STACK said the new 80-acre Loudoun site will offer massive scalability with three buildings, totaling 216MW of capacity and nearly 1 million square feet. The campus will be powered by 100% renewable energy and served by Dominion. 

The first phase is expected to be ready by Q3 of 2023.

The announcement comes in the wake of STACK’s recent expansions at its campus in Prince William County, including the groundbreaking of a 72MW total second phase announced just two months ago and already under construction for 2022 delivery.

“STACK’s forward development in the most challenging markets is our differentiator. Our clients seek speed, scale, quality, and partnership. This new flagship campus exemplifies that,” said Brian Cox, Chief Executive Officer of STACK. “I am proud that our development team was able to deploy its expertise while building strong relationships to deliver the on-demand capacity, in key locations, that top technology innovators need.”

STACK’s latest Ashburn campus news follows recent international expansions including entering the Asia Pacific market via the opening of its Singapore regional headquarters, the initial phase of construction of a 56MW campus in Toronto, Ontario, and a soon-to-be-completed new 24MW facility in Hillsboro, Oregon, which will bring STACK’s Portland-area total capacity to over 50MW.

“STACK’s development team continues to leverage its relationships with utilities, local authorities, and developer partners to establish a strong, scalable presence in critical markets like Northern Virginia, despite land and power scarcity,” added Tim Hughes, Vice President of Strategy and Development at STACK. “Dedication to our clients has driven STACK to secure campus-scale sites and electrical interconnections to allow hyperscalers and enterprises continuous expansion in key markets.”
