Flip-flop qubits: Radical new quantum computing design invented Engineers at Australia’s University of New South Wales have invented a radical new architecture for quantum computing, based on novel ‘flip-flop qubits’, that promises to make the large-scale manufacture of quantum chips dramatically cheaper – and easier – than thought possible.

Test is a key challenge for 5G | EDN The most recent 3GPP (Third Generation Partnership Project) Plenary meeting in West Palm Beach, Florida confirmed that the industry continues to make excellent progress for meeting the goal of having the 5G New Radio (5G NR) physical layer defined by December 2017. But there is still a long road ahead.

Playing with kernel TLS in Linux 4.13 and Go Linux 4.13 introduces support for nothing less than… TLS! The 1600 LoC patch allows userspace to pass the kernel the encryption keys for an established connection, making encryption happen transparently inside the kernel. The only ciphersuite supported is AES-128-GCM as per RFC 5288. The kernel only handles the record layer, that is, it only takes care

Gigabit wireless begins to take hold | EDN At the beginning of last week, Ericsson and Qualcomm achieved a transmission rate just a bit faster than 1 Gbps on Verizon’s commercial 4G LTE network. Ericsson, Qualcomm, and Verizon claim to be the first to have achieved 1 Gbps using commercial silicon and commercial infrastructure. 

New posting category for 5G communications

I have created a new category for 5G telecommunications technology topics. New postings related to 5G technologies will be posted under this category. I have also tried to tag older postings related to 5G to this 5G category. 5th generation mobile networks or 5th generation wireless systems, abbreviated 5G, are the proposed next telecommunications standards

What is edge computing? | Edge computing is poised to boost the next generation of IoT technology into the mainstream. Here’s how it works with the cloud to benefit business operations in all industries There is much speculation about edge replacing cloud, and in some cases, it may do so. However, in many situations, the two have a symbiotic

Antenna measurements with RF noise source

Using the wide band characteristics of SDR radios, it is possible replicate some of the functionality of much more expensive equipment such as a vector network analyzer.  Actually what SDR can do it scalar network analyzer functionality. A scalar network analyzer can measure amplitude, but a vector network analyzer can measure amplitude and phase and
