The software product from evolutionQ is called BasejumpQDN and is designed to help users overcome the limitations of QKD networks. Chief among these is the distance limitation inherent in fiber optic cables due to signal loss. While classical optical communications networks can solve this by installing classical repeaters every few hundred kilometers, the No Cloning theorem for quantum qubits prevents one from copying qubits so creating these types of repeaters is more difficult. BasejumpQDN solves this problem by allowing a user to create a Trusted Node between quantum links that will allow a network to expand beyond the distance limitations. BasejumpQDN [...]

French multi-national information technology company Atos and Brazilian non-profit institution SENAI CIMATEC are teaming together to form the Latin America Quantum Computing Center (LAQCC), a center of excellence for quantum computing dedicated to the business sector. The center will promote adoption of quantum technologies, provide training for workforce development and encourage scientific research. The center will include a unit of the Atos Quantum Learning Machine which is a special purpose simulation system that can simulate algorithms of up to 35 qubits. Additional details about this announcement can be found in the news release located on the Atos website here. May 7, [...]

The interaction of nuclear matter at the atomic and subatomic level can be very complex and difficult to model using classical computers. To help further understanding of what happens with nuclear matter at these levels, particularly under unique conditions like the Big Bang, the U.S. Department of Energy (DOE) is soliciting proposals to research to use Quantum Information Science (QIS) to help scientists better understand these interactions. They have budgeted up to $10 Million for a three year period for support various projects to perform research in this area. The potential scope of the program is quite broad and includes funding [...]

French multinational Thales and Australian company Senetas have announced a post quantum cryptography solution for enterprises and governments around the world. Although most experts believe it will still be somewhere between 10 an 30 years before a powerful enough quantum computer is created that can factor a large semi-prime number and hence break the RSA encryption code used for key exchange, there is a concern about an attack that we call "Harvest Now, Decrypt Later". The "Harvest Now, Decrypt Later" attack could be utilized to collect data that has the characteristics of both high value as well as high shelf life. [...]

Australian company Archer has announced it has signed an agreement to continue its relationship with IBM as a member of the IBM Quantum Network and the associated IBM Quantum Startup program. The participation in these programs is a little unusual because Archer is working on quantum computing hardware while most of the other companies in the startup program are software companies. (ColdQuanta and equal1 are the other exceptions.) Archer had previously joined the IBM Q Network exactly one year ago with an eye on gaining access to IBM's quantum computing expertise and resources and to use IBM’s open source software framework, [...]

Cambridge Quantum Computing's (CQC) has announced that it is partnering with the German Aerospace Center (Deutsches Zentrum für Luftund Raumfahrt or DLR) to use CQC's software to solve partial differential equations that can render a 1D simulation of a lithium ion battery cell. Improved batteries are considered vital as the world moves to more sustainable energy sources. Better modelling will not only help improve parameters of the battery itself, such as capacity, size, weight, charging time, etc., but can also reduce the amounts of lithium and possible other rare materials needed which can have other problems created during the mining process. [...]

Montreal based infinityQ has announced it has developed a quantum analog computer that takes a different approach to leverage quantum effects to achieve high performance for solving complex optimization problems, linear system and FFT calculations. Not much is known about this machine except that it runs at room temperature, is available now via the cloud on an invitation only basis and will make an industry debut at the Inside Quantum Technology New York online conference being held on May 17-21, 2021. Some additional information is available in a news release on the infinityQ website available here. May 1, 2021

QC Ware has a different strategy than most quantum software startups. Rather than create a generalized programming platform and offering it to all end users that allows the users to develop their own programs, QC Ware is focused on algorithm development with a specific focus on creating performance speed-ups in near-term hardware. Their team includes several algorithm experts who focus on creating noise resistant algorithms that utilize fewer resources and gate depth so they can utilize NISQ machines as soon as possible. Since one of the biggest deficiencies in today's machines is the limited gate fidelities, algorithms that have lower gate [...]

By Dr. Chris Mansell Shown below are summaries of a few interesting research papers related to quantum computing that have been published over the past month. Hardware Title: Spin Readout of a CMOS Quantum Dot by Gate Reflectometry and Spin-Dependent Tunneling Organizations: UCL, Quantum Motion Technologies, CEA Leti Institute, Hitachi Cambridge Laboratory and Université Grenoble Alpes For decades, CMOS (complementary metal oxide semiconductor) manufacturing has been the dominant way of fabricating integrated circuits. This group of researchers have demonstrated that the same highly scalable processes can be used to make qubits that are long-lived and have a small footprint. You can view the [...]
